Computers, especially those running on Windows, can easily become corrupt and slow over time. Resulting in unpredictable behavior, sluggishness, incorrect files and software, etc., it gets simply annoying at some point. PC optimization software is there to help carry out usual tasks again and to clean up.
Although Windows 10 brought more advanced system maintenance tools, it is still uninsured against clutter, and may users are still enjoying Windows 7 and other older versions. Optimization tools and repair software typically detect and delete old junk files, boost RAM and boot up time, check registry issues. We took top ten tune-up utilities as suggested by Google search and put them to test.

Top PC optimization software 2018
First, let’s summarize main findings about each utility, with pros and cons, and then you will find performance tests table at the end. 9 out of 10 PC optimization apps have a free version or a trial period along with paid annual license to use, while one app is totally free. Whichever way, they’ll help you optimize your slow PCs for faster response, quick task handling and better overall performance.
PC optimization utilities perform deep scans, find and fix problematic areas. Repair functions may include hard drive defragmentation, registry repairs, RAM and disk space freeing, junk file removal, etc. Some are basic, others are more advanced, while all of them have ‘repair all/fix all’ option. We tested every utility in the same repetitive manner on a 8GB RAM PC on Windows 7 Professional.

We ran each utility on the same PC, in the same environment, repetitively. We didn’t count performance boost in percentage, because it would be inaccurate due to testing 10 apps in a row. In terms of performance, 2 utilities – Advanced SystemCare and Wise Care 365 – found the biggest number of issues, though its relative in a way too. Razer Cortex gave the most considerable RAM boost. But judge for yourself.
