After the scan I tried to investigate the causes, ChatGPT replied that :
Why Does the Error 0x800f081f Persist?
Your system is running Windows 11 build 26100.3476, which belongs to the Insider Preview (Canary Channel). DISM fails because:
You are not enrolled in the Insider Program → Windows Update does not recognize your build as "official."
You are using a standard ISO or Windows Update → these do not include files for Insider builds.
Although you claim that you do not have an active Insider version, your Windows build (26100.3476) belongs to the Canary Channel Insider Preview – which is an experimental beta version.
Now here comes the strange part of the whole story, I was NEVER an insider and I never switched to that channel, is ChatGPT right, how did it happen and how to fix it .
Any help is welcome.
