I have tried this method along with having MS support remoting to my computer and running these a batch file with these commands:
DISM.exe /Online /Cleanup-image /Scanhealth
pause
DISM.exe /Online /Cleanup-image /Restorehealth
This did not work either.
About a week later, another support tech remoted into my Windows 8 Pro and ran VIPRERescue15034 in safe-mode networking. This process ran for about 2-3 hours. The next day the OS8 ran even slower.
Almost every app, or online will stop..(Not Responding) ....then continue.
I also turned TimeBroker back on because there were no positive results from being disabled.
Suggestions?
