I ran sfc /scannow to fix abunch of corrupted files prior to the last trace. Superfetch is in regedit but not in services. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters EnableBootTrace 0 EnablePrefetcher 3 EnableSuperfetch 3 Weird that I can't find superfetch in services. I'll run another sfc /scannow Also tried to install sp1 but a 0x80070057 error came out of it. Still no luck there. UPDATE: Ran another sfc /scannow. it said it found errors and it was going to fix upon reboot. After reboot, superfetch was still not found. Also disabled startup files and services for a clean boot. Superfetch still not found.
