Creating a restore point fails. The following application error is logged:
Volume Shadow Copy Service error: Unexpected error CreateFileW(\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\,0x80000000,0x00000003,...). hr = 0x80070001, Incorrect function.
.
Operation:
Processing PreFinalCommitSnapshots

Execution Context: System Provider
Before creating the restore point the vss writers are all in a stable state:
vssadmin list writers
There are no corrupt shadow copies:
vssadmin list shadows
vssadmin delete shadows /all
No items found that satisfy the query.
I also removed all hidden storage shadow copies in the device manager.
