ReadyBoost: Use Flash Drive as a RAM to speed up your computer

ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards. When you plug a ReadyBoost-compatible storage device into your computer, the AutoPlay dialog box offers you the option to speed up your computer using ReadyBoost. If you select this option, you can choose how much memory on the device to use for this purpose.

When you set up a device to work with ReadyBoost, Windows shows you how much space it recommends you allow it to use for optimal performance. For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your device doesn’t have enough available space for ReadyBoost, you’ll see a message telling you to free some space on the device if you want to use it to speed up your system.

You can enable or disable ReadyBoost for a specific flash drive or other removable storage device. For more information, see Turn ReadyBoost on or off for a storage device.

The ReadyBoost tab lets you decide how much storage space on a removable device to use for boosting your system speed.
Notes

Notes

  • If your computer has a hard disk that uses solid-state drive (SSD) technology, you might not see an option to speed up your computer with ReadyBoost when you plug in a USB flash drive or flash memory card. You may instead receive the message, “Readyboost is not enabled on this computer because the system disk is fast enough that ReadyBoost is unlikely to provide any additional benefit.” This is because some SSD drives are so fast they’re unlikely to benefit from ReadyBoost.
  • In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.

So, you’ve locked yourself out of your PC and, because you are smart and used a good password, and the NTFS filesystem, you now cannot access your personal files. Don’t despair, this guide will show you how to reset the administrator password.

Note: The intention of this guide is to help you reset your OWN password. I am not responsible for any misuse of this tool.

Download the Password Recovery Disk

The first step is to download and burn the password recovery disc.

Download the disc here.

If you are unsure how to burn an ISO image to a disc, follow this guide: Burn an ISO to a CD/DVD.

Boot from the Password Recovery Disc

To boot from the password recovery disc:

1. Insert your bootable recovery disc and shut down your PC.

2. Power on your PC.

3. When your BIOS is loading (if you have a brand-name PC, this is usually when you can see the brand’s logo), press the key that loads the boot options menu (this is usually displayed as an option on the screen and is typically the ESC key.)

4. Arrow down to the CD-ROM Drive option (may also be called Optical driveDVD-ROM Drive,Optical Media etc) and press Enter.

How to Install Android on PC / Laptop

Mobile phones under the android platform always deserve a best place in market. So if you got messed with android OS and want to try it in your netbook or laptop here is the procedure to experiment it. You can install in your memory cards or flash drives to test android OS on your system.
Download android from Android-x86 and copy it in your flash drive or memory card. Scroll down and download it from the stable release section of the site. This will download an ISO file from the website. Also Make sure your memory device having memory more than 256MB and make your memory drive clean before copying android into it.


You also need UNetbootin (Universal Netboot Installer) to run android on your system. So download it from UNetbootin site. It is available for all the leading operating systems. So choose your OS to download UNetbootin from the site.

Now I have downloaded UNetbootin for my windows platform. All you need to do is insert your drive which you going to install your android OS. UNetbootin extracts the ISO file of android OS which you downloaded and install it in the target disk. The first step of your installation is shown in the screen shot below.

After selecting the target disk, android will start extracting from ISO file and installed in your disk. Now your flash drive will get installed with android OS. This may take few minutes depending on the speed of your flash drive.
 Once you get done with the process you will asked to reboot your system. If you wish you can reboot system immediately or else you just exit and run android when you want. Now your system is ready to run android OS. All you need to do is reboot your system with the flash drive. Change the boot setup to boot from removable disk.

In default it will be available to boot from your hard drive. So press F2 on reboot of your system. Go to Boot menu in the BIOS setup and change the boot setup to boot from removable disc. Then press F10 to save your changes and exit from BIOS setup. Now your system will restart and boot from your removable disc. This will bring a menu infront of you with the following options.

Select Live CD- Run Android-x86 without installation. Then your android OS will start booting and you need to wait for few minutes until it gets loaded. After a couple of minutes you will straightly get into your personal desktop. The default applications will be available on the home screen and for more applications go to menu and select the applications you need.
How to Use Android as PC

By default android give access to webcam and Wi-Fi. So that after entering into the menu you can install the apps you need. You can carry your memory card or flash drive to anywhere and use your own android OS. But your apps installed will be gone when you reboot your system or when you put your removable device in another system. This provides a better interface for the persons who are all using the public systems.

Follow these steps, try installing android in your system. share your comments and doubts in the comment box below.

Just download LiveAndroid

How to downgrade from Internet Explorer 9 to Internet Explorer 8 in Windows 7

Downgrading Internet Explorer from 9 to 8 is a feature “hidden” from view in Windows 7. Since there isn’t a download available for Internet Explorer 8 in Windows 7, the only way to revert back is through the “View Installed Updates” menu inside Control Panel -> Programs.

I had to revert back to IE8 since we still have a number of users with Windows XP (which only runs in IE8)

You can remove IE9 and install IE8 using the following steps.

1. Close all programs.

2. Click Start, and then click Control Panel.

3. Click Uninstall a Program under the Programs category

4. In the Tasks pane, click View installed updates.

5. In the list of installed updates, double-click Windows Internet Explorer 9.

Once Internet Explorer 9 has been uninstalled from your system, the computer will require a reboot. After rebooting, your computer should now revert back to Internet Explorer 8.

To disable IE8 or IE9 in Windows 7, go to Control Panel -> Programs. Click on the “Turn on Windows Features on or off” link. Uncheck Internet Explorer 9 (or Internet Explorer 8). The system will then act as if Internet Explorer is no longer installed. You can re-enable it via a simple checkbox.

How to Control Skype in a Corporate Setting.

As usual these instructions and notes are written mainly for me as a cook book to use at various clients.
There is no warranty or guarantee express or implied in these notes so be careful.

If you are a professional network administrator you know that you need to check and often control the software that in your environment.  Skype, while common for personal use is seldom used in the corporate world and for good reason.  There are several important things you need to know about Skype:

  1. Skype is a “distributed application” and so even when you are NOT in a call, Skype is using your CPU and more importantly your bandwidth to route OTHER peoples calls.  On a single computer, this is not often a problem but on a corporate network the resulting bandwidth drain can cause serious problems.
    .
  2. Skype has file and screen sharing which will breach nearly every corporations security policies.
    .
  3. Skype “for home” has no call tracking, monitoring or control mechanisms which will breach some security policies.
    .
  4. Skype “for home” will have corporate users expensing $1.12 calls which will make everyone nuts.
    .
  5. Skype has removed their “Guide For Network Administrators” as of version 3 in about 2007 and stopped making their management templates available.  Fortunately, I have confirmed that the template I provide below functions on the 2010 version of Skype (v4.2) and I certainly hope it continues to function under v5 due out in the fall.
    .

The solutions to these problems is to:

  1. Register with Skype Business and then use Skype Manager.
    • Watch this Skype Manager Video to get the core ideas.
    • Skype Manager will let you create and control accounts in a consistent way
    • Skype Manager will let you print a report of each users calls
    • Skype Manager will let you add core profile information for each user
      .
  2. Download the Administration Templates, add them to your Windows domain, and set your policies.  Note that I used an old “v1.7” Skype admin template from 2006 and enhanced it with a DISABLE SCREEN SHARING option so you will not find “my” “v1.8” template anywhere else on the web but here.
    • If you have a Windows 2008 domain or newer, use THIS .ADMX template
      • Copy these files to your \\<domain>\sysvol\<domain>\Policies\PolicyDefinitions
        • If you do not have a PolicyDefinitions folder, just create one
        • If this freaks you out, read THIS about how to create a central store.
          .
    •  If you have a Windows 2003 domain or older, use THIS .ADM template
      • Use your Group Policy Management Console to IMPORT this template.
        .
    • Skype Group Policy in .ADMX and .ADM Server 2008 and Server 2003 Screen ShotAfter the template is added you should use your Group Policy Management Console to set your policies under COMPUTER CONFIGURATION, POLCIES, ADMINISTRATIVE TEMPLATES, SKYPE
      .

      • I shut down the following Skype Features:
        •  FILE SHARING
          •  Skype offers no antivirus scanning on transfer and I will not intentionally leave malware detection to the desktop AV scanner alone.  It should go through other several scans and it does not so I killed it
          • I don’t want files to easily leave the company.  Data protection is king.
        • SCREEN SHARING
          • I don’t want information leaving the company or accidentally accessed via sharing
          • Users can view others people screens but not share theirs
        • PREVENT SUPERNODE
          • this stops the Skype client from using network bandwidth for OTHER people
        • DISABLE LISTENING TO TCP
          • this stops the Skype client from receiving uninvited connections
        • DISABLE SKYPE PUBLIC API
          • this stops third party plugin / extras from working
        • DISABLE NEW VERSION CHECKING
          • I will update clients when I think they should be.
          • I don’t want users pestered with upgrade notices
            .
    • Apply that new Group Policy to the OU’s you are concerned with and either wait a few hours for them to be automatically applied or just run gpupdate /force manually on the machine in question.
      .
    • If you don’t like the to use Group Policy you can simply create your own registry entries underHKEY_LOCAL_MACHINE\SOFTWARE\POLICIES\SKYPE\PHONE.  You can also download my reg file to get started.
      .
    • Some of you may find this Skype forum thread (particularly the end) to be useful.
    • A thorough analysis of Skype and its security implications for organizations can be found on this  University of Texas page.  Specifically, you may find there detail Group Policy / Registry detail to be quite useful:

    DisableFileTransferPolicy—Disables file transfer to prevent the user from sending and receiving files using Skype.

    DisableContactImportPolicy—Disables import contacts.

    DisablePersonalisePolicy—Disables personalization to prevent the user from changing sounds.

    DisableLanguageEditPolicy—Disables language edit to prevent the user from editing language strings.

    WebStatusPolicy—When enabled, always publishes the user’s status on the Web as Skype buttons. When disabled, prevents the user from publishing status on the Web.

    DisableApiPolicy—Disables the Skype Public API to prevent third-party applications from accessing Skype functionality.

    DisableVersionCheckPolicy—Disables new version checking by preventing Skype from detecting new versions and updates.

    MemoryOnlyPolicy—Runs in memory-only mode so Skype does not store any data on the local disk.

    ListePortPolicy—Sets the listening port where Skype listens for incoming connections.

    ListenPort—Listening port number.

    ListenHTTPPortsPolicy—When enabled, listens on HTTP (port 80) and HTTPS (port 443) ports. When disabled, does not listen on HTTP/HTTPS ports. When not configured, lets the user decide.

    DisableTCPListenPolicy—Disables listening for TCP connections to prevent the Skype client from receiving incoming TCP connections.

    DisableUDPPolicy—Disables UDP communications to prevent the Skype client from using UDP to communicate with the network.

    DisableSupernodePolicy—Prevents the Skype client from becoming a super node or relay host.

    ProxyPolicy—Establishes the proxy policy.

    ProxyType—Establishes the proxy type.

    ProxyUnset—Unset

    ProxyAutomatic—Automatic

    ProxyDisabled—Disabled

    ProxyUnset—Unset

    ProxyHTTPS—HTTPS

    ProxySOCKS5—SOCKS5

    ProxyAddress—Proxy address (host:port)

    ProxyUsername—Username

    ProxyPassword—Password

    The following is a list of configurable registry entries that apply to the Windows Skype Client as taken from the Skype Guide for Network Administrators (HKLM is short for HKEY_LOCAL_MACHINE) (Skype, 2008):

    HKLM\Software\Policies\Skype\Phone, DisableApi, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisableFileTransfer, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, MemoryOnly, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisableContactImport, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisableVersionCheck, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisablePersonalise, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisableLanguageEdit, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, ListenPort, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, ListenHTTPPorts, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisableTCPListen, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisableUDP, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, DisableSupernode, REG_DWORD = {0,1}

    HKLM\Software\Policies\Skype\Phone, ProxySettings, REG_SZ = {string}

    HKLM\Software\Policies\Skype\Phone, ProxyAddress, REG_SZ = {string}

    HKLM\Software\Policies\Skype\Phone, ProxyUsername, REG_SZ = {string}

    HKLM\Software\Policies\Skype\Phone, ProxyPassword, REG_SZ = {string}

    HKLM\Software\Policies\Skype\Phone, WebStatus, REG_DWORD = {0,1}

    These same registry settings are available for the current user at HKEY_CURRENT_USER\Software\Policies\Skype\Phone but the HKEY_LOCAL_MACHINE entries take precedence.

Critical Windows bug could make worm meat of millions of high-value machines

Critical Windows bug could make worm meat of millions of high-value machines

Microsoft has plugged a critical hole in all supported versions of Windows that allows attackers to hit high-value computers with self-replicating attacks that install malicious code with no user interaction required. The vulnerability in the Remote Desktop Protocol is of particular concern to system administrators in government and corporate settings because they often use the feature to remotely trouble-shoot e-mail servers, point-of-sale terminals and other machines when they experience problems. RDP is also the default way to manage Windows machines that connect to Amazon’s EC2 and other cloud services.

That means potentially millions of endpoints are at risk of being hit by a powerful computer worm that spreads exponentially, similarly to the way exploits known as Nimda and Code Red did in 2001. “This type of vulnerability is where no user intervention or user action is required and an attacker can just send some specially crafted packets or requests, and because of which he or she can take complete control of the target machine,” Amol Sarwate, director of Qualys’ vulnerability research lab, said in an interview. While RPD is not enabled by default, he said the number of machines that have it turned on is a “big concern” because it is so widely used in large organizations and business settings.

The bug affects Windows XP and all versions of Windows released since, including the developer preview of Windows 8. It was privately reported by Luigi Auriemma, an Italian security researcher who frequently focuses on vulnerabilities in industrial control systems and SCADA, or supervisory control and data acquisition, systems used to control dams, gasoline refineries, and power plants. Microsoft said there’s no indication the vulnerability is being used in the public to attack Windows users at the moment, but the company predicts that could change. “Due to the attractiveness of this vulnerability to attackers, we anticipate that an exploit for code execution will be developed in the next 30 days,” Suha Can and Jonathan Ness, of Microsoft Security Response Center Engineering, wrote in an advisory published Tuesday.

They urged users to “promptly apply” an accompanying security update. Those who can’t update right away and are running Vista or a later version of Windows should enable Network Level Authentication, a feature that requires users logging in to RDP boxes to have security credentials before gaining access. The RDP fix is one of six security patches Microsoft shipped as part of its most recent Patch Tuesday. In all, they fix at least seven vulnerabilities. Only the RDP bug is rated critical. Four bulletins were classified as important and one was rated as moderate.

How to create a bootable Windows 7 USB flash drive

The USB flash drive has replaced the floppy disk drive as the best storage medium for transferring files, but it also has its uses as a replacement for CDs and DVDs. USB drives tend to be higher in capacity than disc media, but since they are more expensive, they cannot (yet) really be used as a replacement. There are reasons why you would, however, choose a USB device over a DVD disc, and bootable software is definitely one of them. Not only is it faster to copy data such as setup files from a USB drive, but during usage the access times are also significantly faster. Therefore, installing something like Windows 7 will work that much faster from a USB drive than from a DVD (and of course, is particularly useful for the PCs without an optical drive; this isn’t something we should just leave for the pirates to enjoy).

This guide will show you two different ways to create a USB flash drive that works just like a Windows 7 DVD. In order to follow this guide, you’ll need a USB flash drive with at least 4GB of free space and a copy of the Windows 7 installation disc.

Windows 7 USB DVD Download Tool

You are normally given this tool when you purchase from the online Microsoft Store.windows_7_usb_1.png

The easiest way to turn a USB flash drive into a bootable Windows 7 installer is by using the tool Microsoft offers, cunningly named the Windows 7 USB/DVD Download Tool. To get started, download the installer [exe] from Microsoft.com and follow the basic steps to put it onto your computer; you can put it on the computer you plan to install Windows 7 on or another one, it doesn’t matter.

windows_7_usb_2.png

Once it is installed, it should create an icon on your desktop, so double-click that to open. If you can’t find it, use the search function in the Start Menu with a keyword like “USB.” Launching it should give you the above screen, and step one is to find the Windows 7 .ISO file. The tool only accepts .ISO images, so we recommend that you convert yours if it’s in a different DVD image format.

windows_7_usb_3.png

Step two is straightforward: simply choose USB device.

windows_7_usb_4.png

In step three, all you have to do is make sure that you are choosing the correct USB device. If you have other data on the device, move it to your hard drive, another USB device, or somewhere else before proceeding.

windows_7_usb_5.png

The tool will prompt you if it detects data on the device. Once your data is backed up elsewhere, click Erase USB Device.

windows_7_usb_6.png

You will get another prompt warning you that all the data will be wiped. Click Yes to continue.

windows_7_usb_7.png

The format will be very quick, while the copying of the files will take a little bit more time (about 10 to 15 minutes).

windows_7_usb_8.png

Once the process is complete, you should get the above confirmation message. At this point you can close the tool and use the USB drive to install Windows 7. Remember that you’ll have to choose to boot off the USB drive. Before doing so, you may want to open up the USB drive and double click on setup.exe to see if everything looks okay. If you want to be able to do this manually, see my other post on this.
