The message “The system is not in the compact state because Windows has determined that, it is not beneficial for this system” indicates that Windows 10 is not compressed using compact OS feature. The tool is showing “not beneficial for this system” likely because Windows 10 was installed on large drive.

And if compact state is enabled, you will get “The system is in the compact state. It will remain in this state unless an administrator changes it” message.

Step 3: Now to compress the Windows OS, type the following command and press enter.
