Using Tweaking.com Windows Repair v3.6.1.
Have been trying for two hours .
The Windows Repair did not work for me. It kept disabling "Sounds and Audio Devices". Chkdsk /f would solve it for one boot. Upon each successive reboot, I would have to run Chkdsk /f to regain simple volume and mixing controls. I got tired of that pretty quickly. It also did not help me with my Netflix computer-freezing problem (which is why I ran the program in the first place) either.
I backed up the registry using v.3.6.1 before I installed the initial 'Windows Repair'. That backup is still listed in v3.6.1. Unfortunately, I did not do the same with my System Restore being that I figured "Tw Windows Repair" would take care of it, as it claimed.
I selected my restoration point from the toggle bar under the "Restore Register" tab, made sure the fixed items were checked, and clicked 'Restore Now' at the bottom of the screen. I did it from Normal Desktop mode, I did it from Safe Mode (with Networking). No Restoration of the previous Registry occurred. I've repeated the procedure six times.
Please help me to get my pre-v.3.6.1 Registry back, somebody!
