Don't just blow something off if you've not tried it.
With MY shortcut, you don't have to type anything.
All you have to do is click the Extended Cleanup icon on your desktop.
Running 'cleanmgr' will get you almost nowhere into cleaning up all the junk on your HD. You'll get a little short menu of things to remove. It's hardly worth your time.
Using the Extended Cleanup, you will have the options to remove MUCH MORE of the junk that windows stores up on the HD.
I'm NOT just a home PC user.....I do this stuff for a living as I've done for the past 19 years. And PC efficiency and security is my speciality.
So try it, before you try to nix it. OK?
