Only 1Gb left on C after Win 10 installed- was 24Gb

dalchina · 31 Jul 2015

Hi, I started with 38.5 Gb of 62Gb used for win 8.1 Pro. After my failed/incomplete Win 10 attempt I had 1Gb spare.
At what point should the installation clean up? Thanks!

Background:
So my Win 10 Win 8.1 Pro upgrade attempt failed with a black screen/mouse + a rolling white/black screen at erratic intervals, and thanks to this forum I see it's a common problem, and note the Aeroglass/Win P/ Nvidia driver version issue.

Ok, so I only got (with difficulty) to the password prompt (as observed here) - and safe mode didn't get to a desktop display.

Regards, David

You need to run cleanmgr.exe. Search for it in the search bar and it'l be the first entry. Run it for drive c:. When the window appears, click on clean up system files button. It'l restart and give you options to remove. There should be an entry for cleaning previous versions of OS files and those are quite large so tick that and then run it.

You should also consider installing ccleaner which has a wider choice of what to clean up. Make sure you go through the entries and untick things you want to keep.

Hi, thanks swarfega - I'm aware of those two. Question is, is that what people are finding- that they have to clean up manually? 1Gb free on the system partition is small these days, so it's not a good state for a system to be left in. Many programs, left to themselves, write data to the system partition, which is where most people also have their user files and folders.

Guessing, is the system disk/partition filled up like this so you can revert (in the first month I think?)? If so, cleaning up after Windows 10 would remove that option. It follows, does Win 10 clean up after the month is up?

If so, I'd say this is a weakness which might lead to an unusable system.

I always clean up after an install as a matter of course. I don't think this problem is particular to Windows 10.

Many programs, left to themselves, write data to the system partition, which is where most people also have their user files and folders.

Yes, and again I run ccleaner once a week which removes unnecessary files.
