Hello everyone,
I have the same issue on Windows 10 - "System Restore Error 0x81000203" and chkdsk not running due to all volumes are locked (The shadow copy provider had an unexpected error).
I don't have Kaspersky, but don't think it is something with Bitdefender. I suspect AOMEI Backupper. I was doing system backup but this time the program did not show any progress for 20 min and I restarted the computer. Probably it was waiting for Windows to update. After it I did the image without a problem. Soon after, I found system restore is not working and then tried to run check disk it failed too.
I tried many ways described online but non of them worked. I read this FIX here but not sure if this case is the same.
I checked in the registry and found "UpperFilters REG_MULTI_SZ ambakdrv volsnap".
Will Watts, should I run the script?
Please advise!
