System Restore Points Have Disappered

[PhilC]

Assistance would be appreciated. Went to do a System Restore tonight, and
all previous Restore Points appear to have been deleted. Appears to be now
working OK, and I have created one as a test, which appears to work. After
finding problem, I checked the Event Viewer and found the following error
there.

<The System Restore filter encountered the unexpected error '0xC00000A1'
while processing the file 'shell32.dll' on the volume 'HarddiskVolume1'. It
has stopped monitoring the volume.>

Can anyone please explain what this means ? and is there anything I can do
to ensure it doesn't occur again ?

Kind Regards,

PhilC

This could have be done ny a virus. Delete the restore point you've created, performs a scan for viruses and when all is clean, create a new restore point.

Something caused SR to crash and it stopped making points as a safety
measure. The old ones are not likely to be useful, If it has got into
trouble, it is probably sensible to clear it out and let it start clean
too. System Restore. Check 'Disable System Restore', and OK, reboot.
Now have Folder Options - View set to show Hidden files, and *not* Hide
Protected mode ones and delete everything in the System Volume
Information folder on each drive

Start SR up again, and I suggest reviewing the settings for each drive.
There is not much point having it enabled on data drives, and on ones
with System or Programs I would reduce the space allotted if more than
say 1GB - I use 500MB, the minimum is 200 which will only handle maybe a
week of points. But the default of 12% of a drive seems too much for
its own good on modern large drives
