Windows 10 resource usage


One of the good things is the small footprint of Windows 10. In my installation it uses only 8.5GB on the C partition and less than 500MB of RAM.

I am sure that willl grow somewhat with the RTM edition, but it is a good start.


Great spot, I never noticed how slimline this build was.


When I did my upgrade that was one of the first things that caught my eye.
MS did a nice job making the new OS smaller... I hope they can keep this up.

I did an upgrade and my Windows directory is 21.5gb. This is about 8gb more than 8.1 was so it seems old versions are retained. I tried shrinking WinSxS with dsim /ResetBase but it didn't make any difference at all.

Hi there

Did you try removing the Windows.OLD and install files - you do this via the Disk cleanup options -- select system files.

Windows does adjust its memory usage based on how much memory you give it. So it looks like you only gave it 2GB, so it will slim itself down. If you gave it 4GB, it would most likely use more memory since there is more available.

I believe Microsoft may have fixed the bug that counted hard linked files multiple times, which made the WinSxS folder appear larger than it actually was... Or maybe it only applies to new hardlinks that get created (which could be why the folder seems bigger to some).

I have 6GB RAM, pagefile/superfetch disabled and it still takes less then 500MB.

Just came across Brink's Windows.old tutorial: Windows.old Folder - Delete in Windows 10
-edit

My Win10 Windows directory is only about 11 GB
10,968,436,689 bytes

If Jimbo's suggestion does not clean up the space (although I think Windows.old is on C:) then you could compare my listing to a listing on your machine.

I used the following command to generate the attached text file (zipped):
cd
dir windows /s /a /og /o-s /oe > %TEMP%WinList-b.txt

WinList.zip

Comparing the contents of the Windows folder tree is a lot of work

You might consider a clean full install, not an upgrade install.

This will prevent a rollback to Win8 - so think about it first.

That also means you would have to reinstall your applications, so make sure you have the license keys for any purchased programs BEFORE proceeding.

I just checked my 8.1 which runs in exactly the same environment (VMware Player) and the RAM usage is over 900MBs. I do, however, grant that 8.1 is a final system and 10 is a beta. So things may change.

I would take an image or two of the current 8.1 system. Then a rollback is easy and you need not save anything else.
