A few simple things to try:
Use the MS account you originally used to join the Insider program in each sign in belo:
Launch the Insider hub app and sign in
Sign in to your MS account Sign in to your Microsoft account
Launch the Store app and sign in
Some people have solved issues simply by starting Windows in Safe mode - and then restarting in Normal mode. There's nothing you have to do while in Safe mode. It seems that some linkage, binding or other relationship only occurs in safe mode on some installs.
It still could take up to 7 days for activation to occur after you try the above.
You could also try kick starting the Insider program by pressing the Stop insider builds button, then joining again. I'd probably save that for last after the other easy things easy + the activation waiting period.
To determine the install status of your machine, execute the following commands in a Command Prompt (Admin window:
slmgr /dlv
slmgr /xpr
req query HKLM\SOFTWARE\Microsoft\WindowsSelfHost /s
You are running a system successfully upgraded to Windows 10 if
slmgr /dlv does NOT have an Evaluation End Date
- and -
there are no keys under WindowsSelfHost
You are running an evaluation of Windows 10, (aka the Insider Program) if:
slmgr /dlv reports an Evaluation End Date
- or -
reg query returns any keys under WindowsSelfhost
It's also possible that you are running the 30-day trial of Windws 10.
That can be determined form the slmgr /dlv report - the wording might be different, but the information should be in the same area as the
Evaluation End Date information. It might have the word expire in the label reference.
Some confusion might have arisen when people 'migrated' from the Insider builds to an upgraded system. If a system was upgraded but you did not leave the Insider program, then the upgraded system is still participating in the Technical Preview and will be offered build updates when MS releases them to the flight rings. If that is what you intended then there is no issue - just be aware that you are running Preview builds, not an upgraded system. You can always do a Clean install to get back to a Current build install (RTM, Retail... whatever name works for you).
Below the fold are reports from two of my machines
- Win7 Home Prem upgraded to Windows 10
Fowwloed by a Clean install on that machine
- Insider Technical Preview
currently on build 10.0.525
slmgr /dlv & slmgr /xpr
