REMOVAL FAILURE: C:\WINDOWS\Temp\Perflib_Perfdata_26c.dat

Hi

Those are the performance library logs and are legitimate, so likely not part of your issue, these tend to accumulate due to inproper shutdowns or various application crashes.

Try deleting it in safe mode or using one of these


1. Pocket Killbox
2. MoveOnBoot this one, once you dragNdrop the file or browse for its location, deletes the file on reboot, so any applications that have locked the file are not running so cannot lock it before deletion.. my fav!
3. Unlocker

also use them in Safe mode if normal mode doesnt work.
