system and registry settings
System Restore uses a feature called System Protection to regularly create and save restore points on your computer. These restore points contain information about registry settings and other system information that Windows uses. You can also create restore points manually.
C:\WINDOWS\system32\Restore
The folder "System Volume Information" is a hidden system folder located in the root of the drive and is used by windows to hold system restore points. C:\System Volume Information\_ Restore folder

Yes, you can have multiple restore points in Windows. Very often, users wipe all but the last one to save space, but you can keep them on there. It is all determined by the amount of space you reserve for restore points.
The System Volume Information folder is where system restore information is held. I first came across it in Windows ME, it is found in all flavours of Windows XP and Windows Vista. It is a very underated/inderused Windows tool, I have found it to be a life saver many times, I create restore points before and after installing new drivers or software. I manually configure System Restore depending on the number and size of the hard drives on the system. Normally I will turn off System restore for non System Drives, Reserving 12% of a 250 Gig Data Drive is a lot of wasted space.

Yes you can ask it to restore its configuration to an earlier 'saved' restore point. Restore points are saved before Microsoft security upgrades.
A computer makes system restore points quite often. It ranges from when you install/uninstall programs, to just logging onto Windows.
The answer is very hard to answer
You can't. If they are still on the computer, you can open system restore and click "Choose a different restore point". Then click next, and in the bottom left hand corner of the windows, click "Show more restore points". If that doesn't work, they are gone. The OS will automatically delete old restore points.
try RollBack rx - they have a 30 days trial and I think it has what you're looking for.
