Updating to windows vista
So don't be hesitant to do reintall when you find any problem in Windows. If Vista Required a reinstall every 3-6 months there is no way I would ever reccomend it to anyone.
Reinstalling windows is a pain and not only will you have to sit through the operating system reinstalling, but you'll also have to redownload drivers and reinstall programs.
In my case it was the display drivers which needed to be rolled back to earlier version and that enabled the updates once again.
The preferred method is to use the Windows Update or Microsoft Update from the Start Menu.
This method will offer all the critical patches, all the optional patches and all the hardware and driver patches.
Depending on the devices and program you have, that can take a whole day of work.
If you keep an up to date antivirus then there is no reason you should have to reinstall so often.
