Glary Utilities is a fairly light utility suite that takes up minimal resources. It offers a slew of features such as registry repair, startup optimization, disk clean up, space viewer, file deletion, memory optimizer, among other tools. Its affordable, cleans fairly fast, and doesn't drag down a system. Review collected by and hosted on G2.com.

One area that the program could expand on is in system tweaking. It doesn't allow working "under the hood" with Windows settings and features. It's not a huge thing and the program is fairly powerful otherwise. Review collected by and hosted on G2.com.
