There are various free PC optimizers that promise to deliver noticeably faster performance, but not all live up to the hype. That is why we’ve tested all the most popular choices and rounded up those that we think will give your PC a noticeable speed increase, without hidden extras or intrusive ads.
It is worth noting that you can do a lot of these free PC optimizers do yourself using Windows’ built-in system maintenance tools, but that is time-consuming; what is really being sold here is convenience.
If you want more features, a number of these free PC optimizers also have premium counterparts that could perform more complex tasks and give additional tools like secure file deletion and scheduled scans.
Iolo System Mechanic
Iolo System Mechanic removes junk files and unwanted programs, blocks bloatware and undesirable auto-run settings, clears out RAM, and wipes various logs, browser histories, and caches.
Not only does this free up key system resources, in addition, it eliminates traces of your surfing activity to safeguard your privacy.
Its PC optimization toolkit does make a difference; whenever we have tested System Mechanic we have discovered a significant speed improvement, particularly at startup. The free edition is excellent, but both top versions — System Mechanic and System Mechanic Pro — are well worth considering if you end up using it frequently — and Iolo is offering a 70% reduction using the voucher code TECHRADAR.
The actual operation boost we saw after conducting System Mechanic made it our favorite PC optimizer. Continue reading for four more of the top apps around for speeding up your Windows PC.
IObit Advanced SystemCare Free
IObit Advanced SystemCare comes in 2 forms: a free version that covers basic house cleaning, and a Pro version that provides internet speed-boosting, real-time optimization, privacy protection, deep registry cleaning, and 24/7 technical support. That is US$20 (about #15, AU$25) for a year, and the permit covers three PCs.
Whichever edition you choose, IObit Advanced SystemCare’s interface is well designed, simple to use, and unlikely to frighten even the most recent PC user. We would deduct points for a professional that wants to add extra programs – that is hardly in keeping with the philosophy of keeping unwanted stuff off your computer – but they are easy to prevent if you pick a custom installation.
Like the majority of the PC optimizers here, it cleans up folders and files you do not desire, neatens up the Windows registry, and corrects errors on your hard disk — all via a simple, slick dashboard.
Piriform CCleaner has existed for quite a long time, and part of the reason for its continuing popularity is that it cleans the elements of your PC that other free system optimization tools don’t.
There is a paid-for version of the optimization toolkit that provides real-time protection and cleanup scheduling, but the free edition of CCleaner covers the important things such as removing temporary files, eliminating browser caches, eliminating unwanted cookies while retaining the useful ones and so forth.
If your PC just feels lethargic then this is the free PC optimizer to test. It does not have all of the advanced features of programs like System Mechanic, but the stuff it does clear is famous for slowing down PCs.
Ashampoo WinOptimizer 2019
Ashampoo WinOptimizer 2019’s biggest selling point is its versatility — you can scan for junk files, broken registry entries and browser cookies with one click, and erase all of them all with one more.
As an alternative, you can dive deeper by choosing the details’ button to review the results of your scan one by one. Unlike some PC optimizers, Ashampoo WinOptimizer offers you a complete description of every issue it is identified, describing just what it is, and why you need to consider removing it. You may then make an educated choice about whether to erase or maintain it.
WinOptimizer also contains a package of’modules’ for regular maintenance jobs such as defragging hard drives and refining startup processes. These are all tasks that could be achieved within Windows itself, but having them all in 1 location is far more convenient than trawling through menus.
(In case you’re wondering, Ashampoo takes its title from this optimization software, which cleans your PC’like a shampoo’.)
