Once the apps are needed, they're instantly enabled before being disabled again when no longer in use, which means no trawling through background activities or task manager processes.Īltering the Windows registry can be a daunting prospect, too, but over time it can become clogged with missing or broken items when installing and uninstalling software or updates.ĬCleaner's registry tool seeks out the likes of missing shared DLLs and unused file extensions, giving users the option to delete them and reduce the number of system crashes. The feature scans a PC for all inactive programs that might be draining resources and puts them to sleep when not in use, much like what Android does with apps that aren't activated often. With 70% of BSODs the result of problematic drivers, this comes extra handy.Īnother more recent addition to CCleaner Professional is the Performance Optimizer. The feature has a library of over 25 million drivers and 'Portal Matching' tech that can search and find items even when the original manufacturers have abandoned them. You also get a driver updater that scans for out-of-date drivers and can automatically update them all with the click of a button. Taking advantage of the $1 Pro offer will also get you CCleaner's software updater, which can improve security by ensuring apps (over 200 are supported) are running their latest versions.

In the Health Check option, for example, Pro users are able to see and disable startup apps slowing down boot times. The standard cleaning features are available in the free version of CCleaner, but those who upgrade to the full version receive a slew of extras that can improve a PC's performance even further.

Manually removing all this redundant data to speed up a machine can be an arduous task, but CCleaner has been automating the process since 2004.įor the next 4 weeks, you can grab a year's subscription to the Professional version of the app and all its extra features for just $1, saving yourself $29. Much like a home, not giving your PC the occasional virtual cleaning can lead to a build-up of junk: temporary files, duplicates, software leftovers, etc.
