Backdate a system without restore point

[Shehdeep]

I want to take my computer to a backdate but i don't have a restore point on my system as I was able to login to some websites previously on which i am working but now i am not able to do so.

If you didn't set a restore point, im afraid you will have to do a clean re-install.

Even if you DID, you still could not roll back your computer to a previous date. System Restore is not an image backup, instead, it should be called Operating System Restore -- as what it really does, is when a restore point is created, it saves off system files and settings -- but not data files. So, it's not the same as a "time machine" app.
