Basic restore feature isn't suppose to damage the OS, other than to bring it back to a prior date. HOWEVER, if you have a real problem either s/w or h/w its not necessarily going to fix it. Maybe, a s/w one but certainly not a h/w one. I don't know why you needed to even do a system restore which maybe the crux of your problem. Any restore point is just previous stored data on given data, which sits until used. That of itself shouldn't be a problem but if it so happens to become corrupted by some process just sitting there then that relates outside of system restore. If the access of system restore point becomes corrupted *during* the process that suggest yet another problem. For now, you didn't state why you wanted to do a system restore. I *ASSUME* you're using the OS system restore point as well not one provided by some 3rd party s/w. However, again some 3rd party s/w may start a system restore point using the OS based one. For now, you haven't provided why you wanted to do a system restore and I refer to the beginning on my post for possible source of error.
In my experience OS system restore does work, provided no "hard error" or such is present. Often enough some wayward install or user induced task caused a problem. The whole purpose of the restore feature is to return prior to such errors. This isn't a super magic trick but it is one that can be relied excluding what I explained above. Again, I don't why you needed to do a restore in the 1st place. I didn't gleam any info on why from Yahoo answer post.
Hi please look at my last post in yahoo answers
Thanks please can you now tell me is it possible I wrecked my pc, like my harddrive or my OS or my files by undoing the restore , Fred says I did, Brandon tells me I did'nt , I'm confused. Is fred right have I damaged the pc?
Trouble is when I undid the restore I then proceeded to do the restore to the same point I had been trying before , if that did'nt work like said in the yahooanswers link above, then I would undo the change which would'nt work either I did this a few times.
I appreciate your support.
