Uniblue Powersuite Lite 2015 is a comprehensive set of maintenance tools for cleaning up, repairing and optimising your PC.

It includes Uniblue DriverScanner , which checks the device drivers installed on your PC, highlights any that are out of date, then locates, downloads and installs the updates in a couple of clicks. There's also MaxiDisk which is drive optimization software which will analyze your drive and defragment if necessary. MaxiDisk will also cleanse your drive from unwanted temporary, junk and other files clogging up vital space.

And Uniblue SpeedUpMyPC aims to improve your PCs performance through a range of different techniques: disabling unnecessary services, cleaning up junk files, optimising your Internet settings and applying a host of useful Registry tweaks. You get three bonus "Speed tools", too: a CPU manager stops runaway processes from grabbing all your CPU time; the proactive thumbnail generator accelerates Explorer navigation by generating thumbnail images in advance; and Software quick-starter claims it can help applications launch more quickly from the Start menu.

There's plenty of functionality on offer, then, but well-designed and clear interfaces mean it's all very easy to access, even if you're a PC novice. And the emphasis is constantly on your safety, so for instance most of the programs will save your original settings before they make any changes. If there are any problems then you can usually restore those previous settings at a click, quickly returning your PC to normal.

While you are using the free Lite version of the program you only have access to the tools in the speed section - CPU manager, program launch acceleration and proactive thumbnail generator. By upgrading to the PRO version you gain access to many more tools such as registry defragging, system tweaking, junk file removal and much, much more.

We're labelled this as "freeware" as it will install as the basic Lite edition by default.

The 2018 edition brings these changes (see changelog for more):

- 2018 Version
