Hey Diplocaulus
I bet you did not think when creating this post, that you would get over 500 replies of support from the community. And sadly only a handful of generic - "rebuild your machine" - type replies from MS moderators.
Fair play to you!
Though I am fearful, if we see you post another bug in the future, you just know its going to be another epic one again, I wouldn't expect anything less now ;-)
Thank you all for your time and effort on this issue.
Personally, this bug and this forum, helped my company prevent the roll out of Windows 11 to 10,000 machines.
Now this is fixed, and we hope this fix stays in place for the foreseeable future, we may now revisit the idea to start using Windows 11 at our place. But the "lack" of support and speed on this fix has really dented our faith to use Windows 11 in a Corporate Environment.
