Hello,
Im currently on version 26H2 (26300.8935) i was on insider program but i leaved it.
When I boot my windows, it shows me a message telling me to update.
The update tryed is 25H2, a previous version, and it fail every time with the message
The installation failed in the safe_os phase with an error during the operator startup.
I updated all my drivers. Nothing more.
How do I have to proceed ?
Best regards,
Matheo

Being logged in and relinking your
account are 2 different things.
If you don't relink your account to Insiders
it's not going to offer you Insider Updates.
Builds typically come out once a week.

I'm not sure if i'm linked or not.
I guess its the fact that my account is set here, where i hidded my email adress ?Maybe another solution is to leave the insider program ?

2026-08-05T17:47:45.45+00:00 Hi Math,
That was not 1 of the ISO's updated.
Also what does it show if you open
this option:
If you are seeing these options then
you are in the Insider Program.
