Windows 7 keeps deleting restore points

Hi, a new user of windows 7. I've used system restore before and know that windows will delete older restore points once the space allocated for restore points fill up... however, Windows seems to be deleting 2-3 restore points every 10 days or so without me having added newer points (so there was space for the restore points, windows 7 deletes one, two, three or sometimes all and leaves me one that it created itself named "automatic restore point")...

I read that the default period of time for restore points to 'die' is 90 days, so that's not it either. What's happening?

This is interesting. there should be a task in task scheduler to create a new restore point once a week.

Is this task set up correctly?
How much disk space do you have allocated for restores?
you have only one restore point currently? (named "Automatic restore point")

There is a good tutorial you can use for navigation here: System Restore

Nope, no tasks for system restore in task scheduler.
Right now, 10 gb is reserved for system restore. Atm only 1.56 is used.
Yes. This is the first time that this happened like this. Before I just saw a few restore points disappear, but didn't think much of it... until I decided to dig deeper into how system restore works and found out it's unnatural to do this, especially since no new system restore points are taking up the space from older ones.

Yeahs een that, but as far as I know, mine do not disappear right after a reboot. They just vanish for no reason after a couple of days...

Maybe there is another task scheduled for system cleanup that is deleting the not-most-recent restore points.

or a 3rd party program like CCleaner that is set up like that...

I don't have ccleaner... thing is, this is a brand new computer which I've just set up (laptop sony vaio f, comes with all the bloatware and stuff but nobody else on the sony vaio f owner's forum seem to have this problem!)... very annoying.

Do you modify a lot of files a lot? Previous Versions could be what is cause it.

What do you mean? Because this is a new system I did use system restore back and forth quite a few times and programs have rolled back to previous versions during that time.

Well...? Don't leave me hanging like that.
