Regarding the deletion of your Windows.old and the administrator rights, I request you to consult a Microsoft technician before proceeding further. Also I would like to let you know that the locked files cannot be scanned when it is password protected. Please reach us back after reaching the Microsoft support to assist you further.
A whole computer scan identified 789 notifications involving locked files that can't be scanned in multiple categories, 2 drives. Problems below came up in stages but notifications only appeared after I signed into Microsoft account post Windows 10 upgrade.
Most but not all start with C.[BACKSSLASH]`Windows.old (should this directory or file still exist?)
Some are Office15 files
Keyboard is not funtioning can't type 'back slash', key strokes delayed, logged?
Admin rights gone, can enable/save changes for password with screen lock
Log files disabled
AVG funtionality turned off in Firewall supporting locked files not being scanned
AVG PC Tune Up indentifies hundreds of problems each clean up several times daily
First whole computer scan quarentined 2 generic trojans then nothing. I have multiple screen shots - tired of being told that this is not happening. Basically I don't have control of PC and yes I have scanned for Root Kits.
Any suggestions/feedback appreciated, especially from those with similar issues
