Editing registry key can be very complicated and highly risky. Please do NOT try this unless you are absolutely positive that you might mess up the system, and as always, it’s highly recommended that you do a backup of the registry (or whole system) before making any modifications.
Since it would take hours to talk about the registry, I am just going through the very basic steps. You can always refer to the Microsoft website or books for full details. Here’s the most common steps you might ever need to know for basic troubleshooting:

Unregister DLL in Windows XP or Vista
Sometimes we need to unregister a dll file to troubleshoot a problem in Windows XP or Vista. Here’s how to do it:
- From Start –> Run, type “cmd” then click on Open. (Where is RUN in Windows Vista?)
- Type “regsvr32 /u filename.dll” where “filename” is the name of the file that you like to unregister.
Please keep in mind that this involves system modification and can be highly risky. It’s always recommended to keep a system backup handy, in case things go wrong.
Why would you need to kill a process in Windows XP or Vista? We sometimes need to stop a process to diagnose a system problem, such as removing Spyware or computer viruses. One of the easiest yet most efficient way to accomplish this is to use the built-in Task Manager in Windows XP or Vista. Here’s how you do it:
- Press “Alt+Ctrl+Delete“, then click on “Task Manager“. You can also launch the Task Manager instantly if you press Ctrl + Shift + ESC simultaneously. This is much easier than accessing it from Ctrl + Alt + Delete or the taskbar. It works for both Windows XP or Windows Vista.
- Select the process that you want to stop, then click on “End Process“.
It’s advised not to stop a system process. Stopping a system process can cause the computer to hang or freeze up.
How do upgrade from Windows XP to Vista without buying a full version?
There’re a few articles circulating the web on how to upgrade to a full version of Windows Vista from scratch, and only paying the cost of an upgrade from ealier versions of Windows. This is first reported by Marc Liron on his website.
Here’s how it works:
- Install the upgrade version of Vista without entering the product key.
- Wait until the Vista files have been copied across, start the installation again instead of activating it.
- Completed.
That’s it.
