System requirements

CCleaner will run on any PC running Microsoft Windows 7 or above. If you're running one of the following operating systems, you're fine to run CCleaner:

• Windows 10 (all editions, including 64-bit)
• Windows 8 (all editions, including 64-bit)
• Windows 7 (all editions, including 64-bit)
• Windows 2003, 2008 and 2012 Server (all editions)

Since CCleaner is a small, quick program there are no minimum memory or hard drive requirements.

Note 1: For Windows NT4, ME and 98, we recommend CCleaner Version 2.  For 2000 we recommend Version 3.

Note 2: CCleaner does not currently support Linux.
