I have a problem with System Restore only keeping restore points 5 days back at the most. So for example, the oldest restore point I have currently is from September 6, 2007. I've had this Vista x64 install for around a month now. I should have restore points dating back to about August 1st or so.

I've got plenty of HD space too......around 500GB free I believe so that's not an issue. I don't have any viruses. I bet this is an easy fix, it's just that I don't know what that is. Vista is supposed to automatically make restore points every day doesn't it? According to this post at this site, Vista is supposed to save restore points for around 136 years. Vista's System Restore Points are set to delete after 136 years ! - Windows Vista

While I don't need it that long, I'd like it save them for around 6 months to a year or even whatever the default is supposed to be. I had a problem with a Windows update about a month ago. I think it was a security update or something. Anyway, I don't know which one or why, but it borked my system and I couldn't even boot, not even in Safe Mode. So I put the Vista x64 DVD in and went to use System Restore and I didn't have any restore points. I had no other choice than to reinstall Windows. I just want to know why it's doing this and how I can stop it before I have to use System Restore again and I have to reinstall again.

Thanks in advance!
