Hi! I hope someone can guide me to a situation I have. I've got a 1TB SSD drive where the C Drive has my OS (W10 Pro) - D Drive has my Apps and the E Drive, my work files. I can't keep uninstalling and re-intalling W10 and Office 2016 because this will cause me issues on the license activation, even though I own genuine MS Office licenses and DVDs. What I am thinking of doing is to back up the E Drive > then delete it > merge it into the D Drive. I can re-create the E Drive afterwards. This link shows my drive from Disk Management. My question is this: if I carried out this process, would I be able to extend the C Drive partition from the free space in the D Drive, without having to re-install W10 and all my other apps?
