Strange problem, need fix fast !

Another path.... try rebuilding the Icon Cache:

If its a reg problem, i might have actually found a solution to your problem:
(At this point, assume you have considered a rollback already or have none, if you have a backup, try that first!)


Windows does regular registry backups even if ShadowCopy is turned off; if you have a way to boot your PC externally follow these instructions to see if any lost or broken keys can be restored:

!!!!!!!!! Backup the following folder FIRST, in case anything goes wrong: C:\windows\system32\config !!!!!!!!!

Boot your computer externally, anything you have to do so works.

(Your Windows OS can't run while you do it since the RegFiles are going to be in use, and therefor locked.)

Boot from the Windows Installation DVD/CD/USB or whatever you have.

---------
Option ONE (Windows CD):

Choose Recovery Options

Choose Command Prompt

Enter the following commands. Press enter after each one:
(Use correct Drive letters! It might change to D or something else since you are booting externally)

cd "C:\windows\system32\config\regback"

xcopy "C:\windows\system32\config\regback" "C:\windows\system32\config"

Reboot normaly
--------
Option TWO (Anything else):

Manually copy all files from "C:\windows\system32\config\regback" to C:\windows\system32\config

Click yes if asked to overwrite existing files, cause thats the point of this procedure

Reboot normally
--------
If anything happens boot your computer externally again and replace the folder C:\windows\system32\config with the backup you were suppsed to make.





I hope this helps
