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

    Hi Math,

    That was not 1 of the ISO's updated.

    Also what does it show if you open

    this option:

    User's image

    If you are seeing these options then

    you are in the Insider Program.

    Hi Math,

    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.

    Hi Math,

    I don't understand why you are being

    offered a lower build.

    Did you relink your Microsoft account?

    At this point I would pause updates

    and then wait until builds are released this week.
