My Windows 10 machine recently started taking a long time to sign in. Boot, post and getting to the login screen are all fast, but after signing in it takes up to two minutes to reach the desktop. With all the Windows machines I've built and used over the years that's a long time.
I read that temporary files can affect this. I started by running Disk Cleanup. Initially it showed 55.4 GB of Temporary Files.
After running it now shows 55.2 GB.
Why would it only remove 0.2 GB?
Using File Explorer I found that %localappdata\temp% has 57GB of files. Would I be better off just deleting its contents manually? I'm concerned about the unintended consequences, whatever they could be.
Is there a different utility I should use that will actually delete all the temporary files it finds?
