if you've done a restore point then you've backed up your registry...but if you want to be absolutely sure do thisBacking Up Your Registry
- Go Here and download ERUNT
(ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.)
- Install ERUNT by following the prompts
(use the default install settings but say no to the portion that asks you to add ERUNT to the start-up folder, if you like you can enable this option later)
- Start ERUNT
(either by double clicking on the desktop icon or choosing to start the program at the end of the setup)
- Choose a location for the backup
(the default location is C:\WINDOWS\ERDNT which is acceptable).
- Make sure that at least the first two check boxes are ticked
- Press OK
- Press YES to create the folder.
other than that step six is self explanatory...jut calm down and follow their steps
and once you do those steps go here
and download the Windows Installer Cleanup Utility package and run it according to the MS instructions...
if neither of those things help we can take it from there....but the most important thing is you need to stay calm and not freak out...if you wig out you're going to get impatient and you're going to make a mistake that we might not be able to fix
also you don't mention anything that would make me concerned about you turning the laptop off while it's not being used...and there's absolutely no reason to leave it connected to the internet unless you need to download something like the tools we suggest that you use
