It took two WEEKS and multiple complete windows reinstalls to get this one figured out.  Unbelievably, it's happening again just 5 weeks later. :(...

Doggone it, Microsoft!  Right back to where we started from.

AND YET!  Seems there's a solution??!  Take a look:
After a month or more of trying all the standard fixes I was finally able...

In the Registry Editor (click the Start Menu icon and type regedit), go to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WIMMount

FIrst thing to do is make a backup of this entry in case anything goes wrong. Right click on WIMMount and select Export and save the backup somewhere.

Now click on the top level WIMMount entry (if you expand it you will see Instances and WIMMount sub-directories but we will not be using those) and in the right side panel you should see 11 or so entries.

Find the entry with the name "ImagePath" and make sure the Data column shows this: system32\drivers\wimmount.sys

If it does not say this, click on "ImagePath" and change the Value data field to system32\drivers\wimmount.sys
In my WIndows 10 registry, this entry showed something different so I changed it. I confirmed this entry on my two other Windows 10 PC's.

Finally, check to make sure the wimmount.sys file is in this location: C:\Windows\System32\drivers\wimmount.sys

My question:
Assuming editing the value IS the key to the conundrum, the poster mentions that what I need to have in Image path is:


Does that seem right to you?  I mean, without the


And then, why lowercase "s" in system??

What should I fill in here, and using what syntax?  Is


without the C:\Windows\ and WITH a lowercase "s" valid?

Finally, what do you think about the values shown in DisplayNAme - @%SystemRoot%\system32\drivers\wimmount.sys,-101

These seem somewhat malformed?

Fingers crossed.
