I installed Windows 7 Professional x64 on the partition that had Windows Vista Home Premium x64, and it preserved the following folders (and all their contents) in C:\Windows.old:
- Perf Logs
- Program Files
- Program Files (x86)
- Users
- Windows
My question: is there any reason I would need those folders/files (except Users; I have a lot of anime, documents, homework, and work stored in there)? If not, I need to delete them, lol. They're taking up 62.2 GB
