Download Dial-a-Fix by djlizard, save it to the desktop then extract it to it's own folder.

    * Open the folder and run Dial-a-fix.exe
    * 2 windows will open. Close the one in the background labeled Restrictive POLICIES
    * Check the box in section 1, Empty temp folders.
    * Check the box in section 2, Fix Windows Installer.
    * Check the box in section 3, Fix Windows Update.
    * Check the box in section 4, labeled SSL/HTTPS/Cryptography. The 4 boxes under it should be pre-checked
    * Check all boxes in section 5, labeled Registration CENTER.
    * Click Go
    * OK any error messages if received, but write them down and post them here.
    * Restart the computer when done.

Have Windows CD/DVD handy.
If System File Checker (sfc) will find any errors, it may ask you for the CD/DVD.
If sfc won't find any errors in Windows XP, it'll simply quit, without any message.
