One of the reasons I was most motivated to write this article for MakeUseOf was because I found that my computer startup time was crawling, and I would always end up with two or three windows opening that I didn’t recognize. Annoyed with my inability to see everything going on with my computer, I decided to strike out in search for a killer application that would give me that power back.

I am pleased to report that the free utility called System Explorer will return power over your own computer back to you.

The reason that my own computer usually gets so muddied up with junk is not because I don’t know how to track down the running processes, identify the culprits and eradicate the files.

How is this view enhanced? Well, it not only lists every single process running on your machine, as well as all of the details about each process – but if you see one that’s questionable, you don’t have to try and guess what it is.  If you click on the “Check” link, you’ll go to an online database of file type explanations and reviews from experts regarding whether or not the file is considered safe or unsafe.
