I turned off Avira before rebooting in Safe Mode because I want to rename “Avipbb.sys which is located in Windows\System32\Drivers\.Reboot or not, with or without Avira, my attempts still fail and I get the dialog “Access denied”.
Because of that, ShadowProtect Desktop is unavailable. I can’t even upgrade my 4.01 version to the latest 4.05. Below is the error from the upgrading process.
I wish someone can tell me it’s still possible to undo my actions and restore to the correct settings.

hello Ave, upon reading your question my answer is definitely yes! you can restore unwanted changes in to your system by using the Built In System Restore in your Operating System.
heres the guide:
1.Start
2. run command
3. type this to your run command = %systemroot%\system32\restore\rstrui.exe
and then choose the earlier time that your changes has not yet been made.
hope this solution solve your problem, have a nice day!
