How can I get a "Disc Image Tools" menu in Explorer?

Yesterday I was on my client's Windows 10 PC.
In Explorer, I selected a .VHD file, call it MyVirtualDisk.VHD.
And ... a "Disc Image Tools" thingpopped up at the top. I then right-clicked and saw Mount.
I was thrilled. I click Mount and it worked as desired.

Then I came home.

At home, on MY Windows 10 machine, I did the same: I selected a .VHD file and nothinghappened.
Interestingly though: When I select a .EXE file, "Application Tools" appears.
So .... what do I do to get the "Disc Image Tools" behavior that I saw on my client's Win-10 PC?

Hello Donald, and welcome to windowssh blog.

Yes, you should have a Mountitem in the context menu of VHD files. The tutorial below should be able to restore it for you.

Mount Context Menu - Add or Remove in Windows 10

Thanks.
BTW - and for other members:
This is a brand new installation of Windows 10. I never messed with these Context Menus.
This suggests to me that the default is NO MOUNT.
However, my client's machine would, I expect, also have defaults - so that's a little mysterious to me.
No big deal.
I now have a way to control it.
Thanks

You're most welcome.

If you changed the default program to open VHD files with, then it would have removed Mount.

You're most welcome.

Well. I marked this thread "Closed" just assuming it would work.
And it didn't work. So I must have done sumthin dumb.
The behavior after updating the registry is identical to the behavior before. Nothing when I highlight a .VHD file on my Win10 PC.
I will review my steps to see where I could have gone wrong -but it didn't work for me.
Thanks

In that case, see if downloading and merging the .reg file for the list VHDitem in the table of OPTOIN TWO below may help. It'll restore the default association and registry entries for VHD files.

Default File Type Associations - Restore in Windows 10

You're most welcome.

If you changed the default program to open VHD files with, then it would have removed Mount.

In Default programs -> Set Associations, the current default for VHD (Virtual Hard Disk) programs is "Unknown application".
Could that be the problem? What approach can I take to fix it?

You could merge the .reg file for VHD posted above to reset it back to default. If it helps, then you or something has changed the association or its registry entries.

I've given up on this for now.
Doesn't seem to work.
I will see what I can learn by visiting the site where it does work.
