UpdateStar Kahuna is a suite of tools that are designed to help customise, optimise, secure, clean and repair your PC.
The Optimisation section provides easy access to some useful tweaks aimed at speeding up your RAM, file system, hard drive and more. A memory optimiser aims to improve system performance and stability, while a Startup Manager provides some control over the programs that boot when Windows launches.
The Speed Up section includes a hard drive and Registry defragger. Click on Cleaner and you're able to wipe away junk and duplicate files, as well as protect your privacy by deleting your Windows and internet tracks. And the Security section can encrypt, hide, and securely delete programs, as well as blocking specified programs to make sure that they can never run on your system.
Bonus tools in the Maintain section will split and join files, uninstall unwanted programs, or batch rename all the files in a folder with a single click.
And the final section, "Power Tools", includes a tool to customise Windows visual settings (the Start menu, task bar, desktop, folders and more), as well as a system information module, process manager, and a S.M.A.R.T.-aware hard drive monitor.
There's plenty to explore, then, but if that all seems too much like hard work then you can always turn to the Single Click Care feature. This will scan your PC for junk files, dubious settings, unwanted startup programs and so on, then you can remove them all with just one click.
