I have put Windows 10 on my Surface (I5/128/4) and am liking it but doing so has raised a few issues/questions; 1) When I partitioned my drive I didn't really give enough space for Windows 10. I have shrunk the Windows 8.1 partition a bit more and now have 2.5Gb of unallocateed space, but under Windows 10 I can't seem to extend its partition to use that unallocated space (option is greyed out in Disk Management). 2) In doing that I have noticed the 5Gb given to a recovery partition. Given that I have made a USB recovery drive that I have tested - do I need to keep giving such a lot of space to this ? If not, how do I add that space into my Windows 10 partition ?
