Glary Utilities Pro was developed by Glarysoft Ltd. to be a comprehensive PC system utility program, with all kinds of computer maintenance tools for cleaning registries, freeing up disk space, managing drivers, tightening up privacy and maintaining security protocols.
It also includes over 20 other tools meant for improving and optimizing your computer. In each round of our tests, Glary Utilities Pro had a high diagnostic consistency score, and it performed the best overall in our comparison.
The average improvement to our test PC after three rounds of testing was 12.62 percent which, although it was the best result in our comparison, wasn’t enough to make a noticeable difference. In fact, the computer’s performance ranked in the bottom 12 percent of computers in the PCMark10 benchmarking tests both before and after running the optimization tools. In other words, even though Glary produced the best performance improvement, it wasn’t enough to turn a slow computer into a fast one, and you shouldn’t expect anything different.
