So I've screwed up my file permissions by taking random web advice to click on my C:\Users folder and do replace all child object permissions in advanced security settings, in order to properly see my user folder on my wifi network. Now the start bar doesn't work, and a bunch of programs won't function correctly if they need to write/save to folders. Whats my best bet to fix this mess? I'm thinking trying the Windows Repair program, if I was to use that, what things do I need to do (checkboxes etc). Or do I need to reinstall Windows completely? Note while I'm semi competent, I'm certainly no IT person, so newb jargon would be most helpful.
I have the Windows Repair program and all I've done so far is the pre-scan which brought up 42 missing default reparse points which are mostly things in the C:\Users folder. Haven't done repairs yet, as I'm hesitant to do anything to further screw up my PC.
