after some useful tips from you guys i had managed to run 'system restore' on my pc (which hitherto has managed to avoid being fully restored)with just one teeny weeny problem ... the only roll back date was the date i managed to do it tuts loudly and angrily>
... frustrating at times. I've lost automatic restore points for no apparent reason, causing me to make manual restore points for a few days. Then, normal auto points are made without any help from me. At the moment, I'm getting them each day now.
huggyg71's advice is correct - make sure you are allocating enough space for the restore points, though by default the slider is usually way over on maximum. I have 680Mb allocated, which is fine for my needs.
Not being funny here, but you did check back on the < tab for any October entries? I know of someone who'd forgotten to do that. :o) TC.
