I'm using VS2017 Community on Win10 1803.
I'd been putting off updating while fiddling around with another problem (don't add more variables to the issue! :-) ), but finally resolved that, so I downloaded all the updates yesterday. Next thing I know I'm running into unspecified problems, but eventually I realise it's because my Temp folder (which I have on a RAMdisk, for speed) had filled up - 4Gb of stuff hanging around! I suspect a good deal of it from the updates. Had to manually clean-up, as several files were non-deletable (and typical Windows wouldn't just do the others - all or nothing).
Do some updating of my Android emulator, next thing I know the Temp folder is full again! Another 4Gb of files hanging around.
Is there something I can click on or some command I can run which will clean up the temp files after these updates? It's a pain having to do it manually. Oh, BTW, when I tried running the Windows disk clean-up, it didn't work - says it was going to clean up several Gb of files, but when I clicked to continue they were still there.
