If CLEANMGR is run without /sageset or /sagerun, it will start by calculating how much disk space could be saved. This makes the process slower to startup.
Although many of these files are often described as "junk" you should carefully evaluate what they do before deleting them. By default only the Downloaded Program Files and Temporary Internet Files will be selected.
Having a hard drive that is over 75% - 80% full will affect performance because file fragmentation (and automatic defragmentation) will increase. Also assuming you have the default 'system managed size' for the page file, that will automatically shrink to fit in the available space. For a drive that has more than 25% free space, deleting files will not make any difference to performance.
Some cleanup options require elevation, when run without elevation the GUI will include an option [Clean up System Files] which will relaunch CLEANMGR in Elevated mode. When necessary CLEANMGR can take ownership of the files before deleting them.
To enable Cleanmgr on older servers of Windows Server, open Server Manager and choose Add feature, then select "Desktop Experience"
After running cleanmgr on a server you may want to disable "Desktop Experience" again.

The Recycle Bin and Catalog Files for the Content Indexer may appear for more than one drive.
The user's 'Application Data' folder is not available for cleanup in the above list. Many files in Application Data hold system data that should not be deleted. However if you have an application that leaves a significant number of temporary/junk files in App Data, these can be selectively removed from a roaming profile with a VBScript like this.
The 'User Profile/Recent Items' folder can contain many more shortcuts than are useful. A very large number of these can affect logon/logoff times. To clear out the shortcuts:
Echo y| del *.*
Save the following batch script:
Taskkill /f /im Explorer.exe
Then to restart Windows Explorer, just run the batch file.
