I was prompted to install an update for Windows 11 (24H2?) the other morning. The download (4.3GB) completed successfully but the file install couldn't be completed, for some reason.

I gave it another crack this morning and it seems to have re-downloaded the file from the other day, and now my C: drive is running out of space and the install can't proceed:

Is it possible to somehow move 25-30GB of free space on D: and allocate it to C: ? I don't mind moving everything off D: and then blowing it away and moving stuff back to it afterwards.

I'm probably not using the right search terms on Google - plenty on "how to delete a partition" but that's not what I'm trying to do.

Alternatively, is there a way to delete this update file (I suspect I have two copies of it) and then try and download it/install it again?

Run "Disk Cleanup", and when it loads hit the "Clean Up System Files" button. That will free up space. Other than that, work out what is taking up the space with something like "Treesize Free", run in Admin mode.

I have a 120GB partition on my SSD for Windows and it works fine, I don't run out of space. I keep it small so I can take OS images that are a reasonable size, all data goes onto other disks. I don't have any games on the computer though.

Actually I think I might just move everything off D:, delete the partition and extend C: and do it that way.

Yes, eventually I will get a newer, larger hard drive but given we've just had Christmas money is a bit tight at the moment so I'll have to hold off for the moment.
