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 PC optimizers 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 has been around for a long time, and part of the reason for its ongoing popularity is that it cleans the parts of your PC that many other free system optimization tools don't. There's a paid-for version of the optimization 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, removing unwanted cookies while keeping the useful ones and so on.
If your PC just feels sluggish then this is the free PC optimizer to try first. It doesn't have all the advanced features of apps like System Mechanic, but the stuff it does clear is famous for slowing down PCs. Ashampoo WinOptimizer's biggest selling point is its flexibility — you can scan for junk files, broken registry entries and browser cookies with a single click, and erase them all with one more. Alternatively, you can dive deeper by selecting the 'Details' button to review the results of your scan one by one.
Unlike some PC optimizers, 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 optimizing startup processes. These are all tasks that could be accomplished within Windows itself, but having them all in one location is much more convenient than trawling through menus.
In case you're wondering, Ashampoo takes its name from this optimization software, which cleans your PC 'like a shampoo'. If your system struggles when you're trying to get your game on, Razer Cortex could well be the answer. This free PC optimizer suspends unnecessary system processes, clears out memory and defrags your system to get the very best game performance possible.
Razer Cortex is available for Windows 7, 8 and 10, and while the differences won't make you jump up and down in astonishment - for most people the results will mean slightly smoother visuals rather than astonishing performance improvements - it does automate the fiddly process of turning off unnecessary software and services when it's time to play.
