I have Windows 10 running on a 250Gb hard drive. But the latest update hasn't got space to install.
I have removed all of the potentially wasteful Apps, but with no success.
When I look in Defrag and Optimise, there are 2 drives; C:\ and WinRE. WinRE is labelled as "never run" and refuses to defrag.
I assume it is a copy of a Windows install, but would be grateful if anyone knows better.
What is it, and how do I get rid of it?
