I'm wanting to uninstall it so I can install the 64 bit version. I tried looking online, and those keep saying to do a clean install, but not how to do a clean install. I searched for how to uninstall what I have, but couldn't find an answer.
- Back up all of your applications and data files to one or more separate devices, or sets of removable media (e.g. DVDs).
- Verify the backups. Lock at least one set in a drawer.
- Make sure you have copies of all application and O/S licenses, and readable copies of all application-install media, so that you can reinstall them.
- Wipe your hard drive... delete all existing partitions. Ideally, zero out the first few megabytes, so that the entire partition table is cleared. You'll need to boot from some location other than the hard drive to do this.
- Boot the 64-bit Windows installer. It should detect the lack of partitions on the hard drive, and offer to partition it and initialize the file systems. Choose a suitable partitioning scheme and let the installer Do Its Thing.
- After Windows is installed, hook it to a network (behind a good firewall!) and let it download whatever service packs and security updates it needs.
- Reinstall your applications.
- Restore your personal files from the backups you made.
If you can afford the expense, you might find it beneficial to buy a second hard drive (or an SSD) before doing this. Make your backups as above, then remove the old hard drive from your PC, install the new hard drive or SSD, boot the Windows installer, install, restore. Keep the old hard drive around indefinitely as a fallback (in case the new version fails) and as a repository for any important files that you find you forgot to back up properly.
If you've been considering installing Linux in a dual-boot configuration, this would be a good time to do it.
