Windows "add or remove programs" list is empty

First of all, just wait for a few minutes. The list may appear after some time.

If still no luck:

• Highlight and copy the entire bolded text below: 
• cmd /c REGEDIT /E "%userprofile%\desktop\uninstall.txt "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ 
• Click on Start > Run and paste in the text you have just copied. Hit Enter. 
• A notepad document should appear on your desktop called uninstall or uninstall.txt 
• Open it to view the contents
• Look for the "UninstallString" values and copy those into the Start > Run box to uninstall programs
