Be aware that this removes the Windows operating system and license from the device. Thus, if you have sensitive data on your personal computer, UITS recommends that you securely wipe the disk drive. This does not guarantee that your personal files would not be recoverable, however.
If your computer has become slow to the point of being unusable, reinstalling Windows may be the best and quickest solution. Slow to the point of being unusable: Over time (especially after a few years), any operating system can become sluggish due to changes that have occurred (such as installing/uninstalling programs).If your IU network access has been blocked by the University Information Security Office (UISO) due to a virus infection, you are required to reinstall. Reinstalling Windows is not the same as the Windows System Restore utility, which does not help in the case of a virus or malware infection.
Virus or malware infection: If your computer has been infected with a virus, malware or other type of malicious infection, the only way to fully clean it is to back up your files and reinstall Windows.Reinstall Windows if you have any of these issues: If you're using Windows 7, UITS strongly recommends that you upgrade to a new operating system. Microsoft ended support for Windows 7 on January 14, 2020.
