6/ CleanMyPC


Why are we stopping active development?

At MacPaw, we have made the strategic decision to focus our system maintenance and cleaning utilities on the Apple ecosystem.

Since honesty and caring for users has always been part of our core values, we have decided to announce that we will no longer be actively developing CleanMyPC. This will allow us to focus on our flagship product, CleanMyMac, and bring more valuable features to our users.

What does this mean for users?

1. You can still use CleanMyPC. It remains secure, stable, fully functional, and supported on all PCs that meet the system requirements:

  • Windows 7, 8, 10 or 11
  • 50.2 MB of disk space to install CleanMyPC
  • 2 GB of RAM

2. Windows 11 is the latest supported operating system. CleanMyPC may work on future versions of Windows, but we cannot guarantee the stability and security of the application and your data.

3. Only critical bugs in CleanMyPC will be fixed in the future. There will be no new features, changes, enhancements, or compatibility updates for the latest versions of Windows.

4. CleanMyPC will switch entirely from subscriptions to licensing.

  • All active subscribers will automatically receive a full license with no expiration date. The transition is free; you will not need to take any action or re-enable CleanMyPC on your computer. Once your new license is active, we'll send you an email about it.
  • To check the type and status of your license, you can use the online license manager or the help dialog of CleanMyPC. The subscription manager will no longer be available for CleanMyPC.
  • If you have an active CleanMyPC license, there won't be any changes for you, so you can continue to use the app as usual.
  • For new users, only one-time purchases (licenses with no expiration date) will be available on the MacPaw Store.
