Windows 10: Open and Use Disk Cleanup in Windows 10
Just note that checking the System Compression box isn't for deleting files, but to only compress them to save the amount of space displayed for it in Disk Cleanup.
Thanks for the info.
Dang it, I will leave it alone then.
MS tech's don't know much more than we do.
I was of the understanding it compresses non essential system files but I could be mistaken.
We will have to wait to see what happens to this in future builds then.

The compression works extremely well - 85% for windows and 90% for program files - my windows 10 install (including 51 programs) is (just) under 3GB if you exclude page file and user data etc which is smaller than the ISO I installed it from - see here Microsoft promises less disk space Win10 - Windows 10 Forums
Tutorial updated to add OPTION TWO for extended Disk Cleanup.
Is the system compression option the same as using the command-line function+option:
So for instance this queries the current state:
And these commands change the state to be on or off.
I seem to remember that compactos is only recommended for solid state drives, and indeed the System Compression option doesn't appear in Disk Cleanup on my old laptop with spinning disk.
I believe so, but I have never used it since it would never be good for performance.

I might give it a try. I've been using CCleaner for quite sometime. Does anyone know how the two compare with each other?

does anyone get the disk cleanup tool pop up on its own once a day around a certain time?
it does for me and i cant work out why
In Windows 10 I can find disk optimize by using the search engine in settings, and typing in: "Disk defrag and optimize". Or by right clicking the drive in question > Properties > Tools tab.
But it doesn't show the folder location.
On my 9860 Enterprise version I can find the disk clean up tool in the start menu. On the 32 and 64 bit pro versions it can be easily missed as it is nowhere to be found in a menu. When you type "Disk Cleanup" in the start menu search the option you...
To Windows updaters (those who've upgraded rather than done a "Clean install").
This is also especially good if you are using smaller capacity SSD's for your installation or even VM's where you don't want to use too much disk space...
