Perform a clean install with Windows 7 Upgrade

Paul Thurott and friend have worked out how to do a clean Windows 7 installation whilst only using the Windows 7 upgrade disc.

The instructions are as follows:

  • Perform a clean installation using the Upgrade disc.
  • Install all pending Windows Updates.
  • Open regedit.exe from the Start Menu.
  • Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/
  • Change MediaBootInstall from ‘1’ to ‘0’.
  • Open the Start Menu again and type ‘cmd’ — use ctrl+shift+enter to run it as an elevated-permissions user.
  • Finally, type slmgr /rearm — and press enter.

You can now reboot and activate Windows 7 by running the Activate Windows utility, type in your product key and it should now work.

Restore the Quick Launch toolbar in Windows 7

One of the first things I noticed when I installed Windows 7 was the missing Quick Launch toolbar, this is mainly because the functionality has now been integrated into the main taskbar but if you desperately need it back you can follow the steps below:

    • Right-click the taskbar and select Toolbars > New Toolbar
    • In the folder selection dialog, enter the following string and click Select Folder:
      %userprofile%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch

The quick launch toolbar has now been setup, to make it look like the old version you can remove the title and text associated with the icons by first unlocking the taskbar and then right-clicking the quick launch toolbar and deselecting ‘Show text’ and ‘Show title’. Whilst the taskbar is unlocked you can also rearrange to put it in your preferred place on the taskbar.

How to disable real-time protection in Microsoft Security Essentials

Microsoft has just released their new free anti-virus product called Microsoft Security Essentials, it has been in public beta for a while now but just been released to the masses, I’ve only just installed it on the whole it seems as good as an anti-virus program from the makers of your operating system would be. One feature that I couldn’t easily find was how to disable the real-time protection on the fly which would be handy for when I want to play games without any interference from the real-time scanning. Currently the only way to do this is listed below:

  1. Open the main program window by either double clicking on the taskbar icon or running the Microsoft Security Essentials shortcut on your desktop.

    Microsoft Security Essentials - Home

  2. Click on the Settings tab and then click Real-time protection in the box on the left, to disable the real-time protection untick the tick box in the panel on the right and then click the Save changes button. It has now been disabled.

  3. Just in case you weren’t sure this was a bad thing the Home tab has now been changed to warn you that you are at risk, to turn real-time protection back on it is as simple as clicking the giant red Turn on button once you are ready.
