Hi Tom Klima,
The Smart App Control message is separate from your Windows Insider registration. It means Windows blocked a particular file or app because it could not confirm that the item was trusted or safe. It does not necessarily mean that your Insider registration failed.
To check the status directly, open Settings > Windows Update > Windows Insider Program. If you see a linked account and an Insider channel such as Canary, Dev, Beta, or Release Preview, the device is configured to receive Insider builds. If the page shows Get started instead, the device may not currently be enrolled.
You can also press Windows key + R, enter winver, and check the OS build currently installed. However, the build number alone does not confirm whether your account is registered, so the Windows Insider Program page in Settings is the more useful check.
Regarding the blocked file, could you clarify:
- What file or app were you trying to open?
- Where did you download it from?
- Does the warning appear when opening Windows Settings, or only after downloading or running a separate tool?
- What is the exact filename shown in the Smart App Control notification?
For now, I would not recommend turning off Smart App Control or trying to bypass the warning, especially if the file came from an unofficial source.
You can also refer to Microsoft’s official guidance:
- Join the Windows Insider Program and manage Insider settings
- Smart App Control frequently asked questions
Thank you so much for your understanding.
