The VSS service no longer seems to work on Windows 10 and 11
Recycling Computers  is my hobby so if you have any old PCs or Macs..

Tried removing all other VS providers such as EaseUS but still no difference - now seeing this:

 backup-failed.png You have insufficient rights to see the content.

A volume shadow copy service operation failed. Please check the VSS and SPP application event logs for more information. (0x807800A1)

Additional Information:
The writer experienced a non-transient error. If the backup process is retried the error is likely to reoccur. (0x800423F4).

So it is just backup that is experiencing the problem - can I re-register the writer somehow?
