There are a bunch of command-line switches to customize the output and what you are looking through, but we’d recommend using the Process Explorer version most of the time, because it’s simple.


This command line utility opens up the Registry Editor and navigates down to the key that you specify as an argument on the command line. No more manually clicking through the tree… assuming you use it. The syntax:

regjump <registrykey>


This converts numbers from hex to decimal and the other way on the command line.


This utility very quickly enables automatic login for your account. Just enter your password, click Enable, and you’re done. You can also use this to disable automatic login if it is enabled and you don’t feel like figuring out how to switch it back.

It’s worth noting that enabling automatic login in Windows is really easy in the first place.


This simple utility reports the effective permissions for files and folders… and registry keys, and processes, and a lot of other stuff. Basically, permissions can be really complicated, so this utility shows what an account actually has permission to do with the object.


This utility is really useful, as you can completely audit the permissions and who has access to files, folders, and registry keys on your system. If you have a really complicated security setup, this tool will let you figure out who has access and see if you’ve made a mistake somewhere.


This utility is actually a shell extension that lets you quickly run an application as a different user, which was really useful back in the XP days when there wasn’t a good way to run applications as Administrator if you had a standard user. It’s still quite useful in the enterprise environment (for older computers).

Note: this feature is built into Windows 7 and 8, but hidden behind the Shift + Right Click menu.

Installing is simple, just use this from the command line:

shellrunas /reg

And uninstall is equally simple:

shellrunas /unreg

To use once you’ve installed it, just right-click on any executable file and choose the Run as different user option.

And then enter the username and password for the alternate user.


Finds and deletes registry keys with null characters in the name. Probably not something you want to do.


This utility remaps your CAPS LOCK key to CTRL instead.

BlueScreen Screen Saver

Yep. ┬áThis one is loads of fun — just install it by right-clicking and choosing Install, and then you can enjoy a fun BSOD all the time.

That’s all there is for this lesson of Geek School. Stay tuned next week for even more great tutorials.
