This tutorial shows you how to gain access (unlock) a registry key that is locked by Windows ,and make your computer have sufficient access to the locked key you are trying to access.This error usually happens when you uninstall, install, or reinstall software on Windows Vista or other Windows version. The simpest way to fix this problem in Windows is to use Regedit to modify the permission settings and ownership settings in Windows Regedit.
The locked registry key error I have encountered when trying to install, update, or uninstall Microsoft Office 2007, Visual Studio 2005, MS SQL 2005, iTunes Quicktime, Opera Web Browser, Open Office and a few other applications in Windows Vista and 7. Locked registry keys sometimes also prevent Windows Update from updating your Windows and Microsoft based Software.
Sample Error message I got when I tried to uninstall Visual Basic 2008. All you have to do is change the registry key permission in Windows registry editor(regedit) to fix this problem.
