WinSxS is merely 9 GBs, SysWOW64 and System32 around 10 GBs when put together, but I have no idea where the other space went. We are talking 63 GBs for Windows folder, which is about 53% of my drive. No, buying a larger drive is not an option I'm considering for this machine. Checked the Temp folder, SoftwareDistribution, Assembly (1GB each), hibernation settings (off), malware (none), SFC clean... Ideas?
