A reinstall of Windows Vista is usually required for bad viruses or if you just want to completely wipe your hard drive. It's important to note this will completely wipe the targeted drive that Vista is put on. I would give yourself at least a good hour to reinstall Vista and be sure to not do this on a day you'll need your computer because after you reinstall you will have to reinstall all your programs too.
Things You Will Need
- Your installation disk, whether CD or DVD.
- Your Windows product key (25 characters). You can find your product key either on your computer or on the installation disk holder inside the Windows package. It should look similar to this:

Step 5On the Type your product key for activation page, type your 25-character product key and click I accept the license terms. You usually don't have to enter the product key right away but it will prevent any problems during activation.
Step 6Follow the instructions on each page until you get to the What type of installation do you want? page and then click Custom.

Tips & Warnings
- Before reinstalling Windows, be sure to save all your files to another source (DVD, CD, Flash Drive, etc.). Reinstalling will delete everything on the drive.
- You may need to disable all anti-virus software before starting. Sometimes this software interferes with the reinstallation.
- Be sure to install new or existing anti-virus software after the installation is complete. If possible, do this before you connect to the internet. Since Windows erases all old files, your computer will be vulnerable to viruses at this point.
