So windows gives you a recovery 10gb space. i cant really use 10 gbs as a back up and i have a network back up so i dont need it. so i deleted the volume and now i have 10gbs of unallocated space that i cant do anything with. how can i add this 10gbs back to my C drive with out making it into a D drive. i have tried to extend the c drive space but it wont let me and i have defraged my computer so what do i do?
