Anniversary Upgrade W10 dual-boot license change
I've read different threads/posts about Anniversary Upgrade license/activation changes/issues/questions.
My situation is different than what I've read, so i created this thread as an fyi for anyone interested in multi-boot.
Here's what happened for me with a multi-boot PC with 2 Win 10 OS's:
The Anniversary Update changed my Insider Preview W10 OS from a license with an expiration date to a permanently activated license.
This OS is not a free Upgrade license, it is the OS I installed before the official release of the free upgrade offer.
It always has been an Insider Preview OS with an expiration date until now.
This PC also has a W10 RTM (not an insider) OS that was the free upgrade from W7 to W10.
The W10 RTM OS has always been a permanently activated retail pro license.
I use the same MS Outlook.com address on both of these OS's, and i also have a Local Admin account on each OS.
To me, it seems the Anniversary Update "applied" my permanent RTM OS upgrade license to my Insider OS that should have an expiration date.
The Anniversary Update also changed my Local Admin account to a Local Standard account on the Insider OS.
Each OS is on a different drive, and all other drives were disconnected when installing the Anniversary update except the drive/OS being updated.
From what i see, i now have 2 permanent W10 OS's.
I should only have 1 permanent, and 1 with an expiration date.
