Hello,
I'm running Windows 10 Pro 19042.1110.
After some weird behaviors I noticed (an MSI installer that wouldn't ever go further than the first preparation window, plus an extreme event today in which, after plugging in a USB SD card reader, multiple devices got disabled/unrecognized including one of my secondary drives), I checked the Event Viewer and found multiple instances of this error:
Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {b5946137-7b9f-4925-af80-51abd60b20d5}. Routine details IVssSnapshotProvider::IsVolumeSupported() failed with 0x8000ffff [hr = 0x8000ffff, Catastrophic failure].
Operation:
Check If Volume Is Supported by Provider
Add a Volume to a Shadow Copy Set
Context:
Execution Context: Coordinator
Provider ID: {b5946137-7b9f-4925-af80-51abd60b20d5}
Volume Name: \?\Volume{cc00bf99-eb73-4799-81b2-b311f10d500f}\
Execution Context: Coordinator
\?\Volume{cc00bf99-eb73-4799-81b2-b311f10d500f}\ is my C: volume.
Once I started reading about VSS, I tried opening "System Protection" or "Create a restore point" and got this error plus a set of three additional errors, identical to the one above, but there was one for each of my drives/volumes (C:, D:, E:).
One major thing I noticed is that "vssadmin list volumes" returns "No items found that satisfy the query". On another working system, this command returns at least the C: volume.
This system has been working fine since April, when I rebuilt it. No major software installations were done lately (apart from Wireguard updates), nor do I use utilities like CCleaner.
I don't have backup software installed, since they seem to be often related to this error.
I already tried DISM, SFC and various other suggestions I found online (like a missing "UpperFilters" registry key) to no avail.
Running a disk check throws an error and logs the same error in the Event Viewer. Running an offline disk check makes no difference.
I also tried enabling VSS debug tracing via registry, but the trace file never showed up.
Update: it also now decided that it doesn't want to shutdown... It looks like it's doing its thing ("shutting down" screen) but then, after a brief black screen, the desktop pops back in and automatic startup applications are started!
The error in event viewer is: volmgr Event ID 45 "The system could not sucessfully load the crash dump driver."
Any suggestions on how to troubleshoot this issue?
Thanks
