Auslogics Windows Slimmer is a full-service option to clean up useless data uninstall software, including obsolete Windows versions.

The goal here is to slim down non-essential data that takes up precious space to help improve your machine's performance and speed. Over time your PC accumulates items that are no longer needed (or ever needed), including some non-optimal settings, unused system apps, in the background data transmitting options, etc. These take up space that wastes resources and are detrimental to the overall efficiency of your machine. You need to periodically perform a clean-up of these junk items to allow your machine to operate at its best. In addition, things such as old System Restore points, Windows Update files, outdated Windows libraries, or disabled system components can take up a large amount of disk space over time and reduce performance.

Windows Slimmer is designed to enable any user with a simple option to remove unneeded Windows components. It is capable of uninstalling obsolete or unused apps and tweaking your machine's settings to reduce the footprint of your OS on your drive. It also reduces the amount of memory and CPU power needed for privacy protection by blocking unnecessary data transmissions. Next, you choose the type of maintenance you wish to perform; one-time maintenance allows you to target specific files and data like disabled components in the Windows.old folder. The other is regular maintenance, which, as the name implies, is to clean up those areas that need constant attention like memory dump files, the recycle bin, temp and cache folders, etc. Lastly, you have the app list clean-up, where you can uninstall any app from your machine. This option also includes an app rating key providing you with an at-a-glance indicator of the app's trustworthiness, but we are unsure exactly where the rating was compiled. That said, it is another excellent option for cleaning out junk and providing some always needed space.
