Disk Management Not Responding

[Joe Lancer]

So I wanted to shrink my C: drive to install Windows 10 and dual boot. Although whenever I open Disk Management, I right-click and click shrink, then it doesn't respond. Any help?

You're not suppose to do that. The proper procedure is to partition your drive if you want to install a second O/S.
