It may surprise one or two to learn that System Restore in Vista retains all restore points for more than 136 years. A bit of an increase from the 90 days XP held on to them.

If you want to change this to something more sensible, if only to save disc space click here

Sorry that link struggles a bit

Set out below

Open regedit and go to
HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersionSystemRestore\Cfg Double-click the DiskPercent.
The default is f (in hexadecimal) which is 15 in decimal. For making it say 10% type 'a'

Now again, how frequently you'd like to have your SystemRestore points auto-created can also b configured as follows :
Open regedit and go to
HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersion
\SystemRestore

You can change the value RPGlobalInterval from its default setting of 86,400 seconds (24 hours) to, say, 43200 (a8c0) if u want it created every 12 hrs.

As and how your new restore points get created, the older ones get deleted due to the availble space contstraint.

Otherwise by default, in Vista, SystemRestore is set to delete restore points after roughly 4,294,967,295 seconds or 136 years, which was a mere 90 days in XP ! The idea apparantly, is to delete them only when absolutely necessary due to space constraint!!! But err...136 years !!!

But unless u want ur grand-children to see ur restore points you can change this interval too. Change the value of RPLifeInterval in the same key; a setting of 7,776,000 seconds (or 76a700 in hexadecimal) is equivalent to 90 days.

Just to add to Ventanas' post :

Hexadecimal "FFFFFFFF" is the maximum that can be stored in 32 bits. In decimal it represents 4.295 billion (more than 136 years in seconds). So, if you don't move on to a 64 bit computer your PC will encounter the bug in 2037.

I'm sure we'll all be 64 bit by then so, as Nick Thingy says, "Please, don't have nightmares".
