Install on another drive other than C?

So i have the latest windows 10 version, but i cannot seem to install apps to any where except the C drive. And the option to change is disabled. See image attached.

Why is it disabled? How do I get it to work ?

I am on windows 10 pro if that matters.

No one knows?

Will this tutorial help ?

It says i am on build: 10240

So i am on an old build, why isn't it updating? I did windows update, doesn't seem to be updating it though ?

What build/version of 10 are you on? Run WINVER from cmd line or Cortana. I am on 10586.29 and all is fine, not greyed out. In the link davidhk gave you, there is a comment stating MS was withholding that option for a while. I just wonder if you are on an old build/version.

You are right. The Move option is not doing anything.

By the way, I am on 10586.29 and I don't get what you showed in your screenshot.
I clicked on the This PC and not drop down box appeared.

How are you guys on a later version than i am ? I thought it would update on its own? Do i have to force it to update the build?

Oh, wait a minute. I spoke too soon. I do get the option to choose which drive to be used
My apology to f14tomcat

Thanks i'll look into it. Seems a hassle, hope i don't lose my software on my C drive. Is it likely a bug that my OS is not updating it's build?
