Windows Slimmer is designed to enable any user a simple option to remove unneeded Windows components, uninstall obsolete or unused apps and tweak your machine’s settings to reduce the footprint of your OS on your drive smaller, and also reduce the amount of memory and CPU power needed for privacy protection by blocking unnecessary data transmissions.
You have a choice for the type of maintenance you wish to perform; one-time maintenance which allows you to target specific files and data like disabled components, 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 to the trustworthiness of the app, but we are not sure exactly where the rating was compiled. That said, it is another nice option for cleaning out junk and providing some always needed space.
