I'm trying to remove AOMEI Backupper 4.0.2 from my PC. I installed a trial and found it can't do what I need it to do. Now I can't remove it without killing my PC. After removal the PC will bootloop 3 times, the 3rd time it will go into "Automatic Repair" and fail. Luckily I can use advanced options > System Restore to recover the machine.
I've narrowed it down to these 3 drivers: ambakdrv.sys, ammntdrv.sys, amwrtdrv.sys. Even unchecking these drivers in Autoruns will cause the system to fail.
I had Revo Uninstaller monitor the installation of this product and I have all the logs for this install, yet it still fails to uninstall AOMEI without killing the machine. The default un-installer fails because it can't find uninst000.dat.
How do I remove this software from my machine? How do I completely remove: ambakdrv.sys, ammntdrv.sys, amwrtdrv.sys without breaking the current Windows Install?
I've successfully removed it by:
- Created restore point and USB rescue drive.
- Booting into Safe mode.
- Using AutoRuns, unchecked the three drivers.
- Using Revo Uninstaller, did a Custom Uninstall and manually went through every item.
- Refreshed AutoRuns and deleted any entries left behind.
- Using registry-finder, scanned entire registry for anything I thought might be related. I did not find anything in LowerFilters or UpperFilters.
These are the same steps as before, except this time in Safe Mode. I had tried so many things that had failed I figured it was a lost cause and I didn't want to try again until I had some more info. The whole recovery process after failure takes about up to an hour. So after the 5th time, I was done messing with it. Took a while to nail down because I had uninstalled 8 different programs through Revo at once. First time was a surprise (been over a week since last reboot and Windows had installed updates on that shutdown), second to verify uninstalling the programs caused the issue, 3rd to nail down the program, 4th to try something different, 5th after unchecking the drivers in autoruns.
