IoLo System Mechanic Review

IoLo System Mechanic is a brilliant free PC optimisation tool that removes junk files and unwanted apps, blocks bloatware and unwanted auto-run settings, clears out RAM and wipes various logs, browser histories and caches. Not only does this free up key system resources, Iolo System Mechanic also eliminates traces of

your web browsing activity to protect your privacy.

Its PC optimisation toolkit really does make a difference; whenever we’ve tested System Mechanic we’ve found a significant speed improvement, especially at startup. The free edition is excellent, but the two premium versions – System Mechanic and System Mechanic Pro – are well worth considering if you find yourself using it regularly. The genuine performance boost we saw after running System Mechanic makes it our favourite optimisation tool.

IObit Advanced SystemCare Review

IObit Advanced SystemCare comes in two forms: a free edition that covers basic house cleaning, and a Pro version that adds Internet speed-boosting, real-time optimisation, privacy protection, deep Registry cleaning and 24/7 technical support.

Whichever edition you choose, IObit Advanced SystemCare’s

IObit Advanced SystemCare offers a hands-off approach to optimisation.

interface is well designed, easy to use and unlikely to frighten even the newest PC user. We’d deduct points for an installer that wants to add additional programs – that’s hardly in keeping with the philosophy of keeping unwanted stuff off your computer – but they’re easy to avoid if you choose a custom installation.

Like most of the free PC optimisation software here, it cleans up files and folders you don’t need, neatens up the Windows Registry and corrects errors on your hard drive – all via a simple, slick dashboard.

Piriform CCleaner Review

Piriform’s CCleaner has been around for a long time, and it’s one of our favourite go-to tools for cleaning up the detritus that can accumulate on any computer.

Part of the reason for its ongoing popularity is that it cleans the parts of your PC that many other free system optimisation tools don’t, and it’s easy to use too.

CCleaner can help rid your PC of unwanted apps, files and tidy up the Registry.

There’s a paid-for Pro version of the optimisation toolkit that adds real time protection and cleanup scheduling, but the free edition of CCleaner covers the important stuff such as removing temporary files, getting rid of browser caches, and removing unwanted cookies while keeping the useful ones and so on.

If your PC just feels sluggish then this is the app you should try first. It doesn’t have all of the advanced features of tools such as Iolo System Mechanic, but the stuff it does clear is famous for slowing down PCs.

Ashampoo WinOptimizer 2018 Review

Ashampoo WinOptimizer 2018’s biggest selling point is its flexibility-you can scan for junk files, broken Registry entries and browser cookies with a single click, and then erase them all with one more.

Alternatively, you can dive deeper by selecting the Details button to review the results of WinOptimizer 2018 Isa fast, thorough scanner and a suite of well-designed maintenance tools.

your scan one by one. Unlike some PC optimisation tools, Ashampoo WinOptimizer gives you a full description of each issue it’s identified, explaining exactly what it is, and why you should consider removing it. You can then make an informed decision about whether to erase or keep it.

WinOptimizer also includes a suite of ‘modules’ for routine maintenance tasks like defragging hard drives and optimising startup processes. These are tasks that can be accomplished in Windows itself, but having them all in one location is incredibly convenient.
