Re: Why would you do an in-place/repair install on Vista and Windows 7 ?
Windows has many files that can be corrupted by dodgy installs, and things like file extensions can be corrupted and default drivers corrupted. Quite often, after a PC is cleaned after having malware, various system files and extensions have been damaged or lost, so a repair from inside the OS can be used to repair this damage. The computer will boot, but you'll be getting error messages and occasionally BSODs.
