Known issue: Windows or Office sign-in issues after Windows update – Tobii Help Center

Some Windows PCs may show Microsoft or Office sign-in problems after installing Tobii Software together with the Windows update KB5060842.

Repeated sign-in prompts or sign-in failures in Microsoft Office apps, including Outlook
Microsoft Store apps that fail to open or update
Windows features that rely on a Microsoft account not working as expected
In some cases, parts of the Windows interface (such as the Start menu) not responding

Windows update KB5060842 introduces system changes that can conflict with the current Tobii Software installer under certain conditions.

We are working on an updated installer that prevents this issue in future installations.

🛠️ How to fix the issue

If the device is already affected, normal behavior can usually be restored by resetting the relevant system settings.

A PowerShell fix script is available for this purpose.

Download the script HERE.
The file is usually saved to the Downloads folder.
Open the Start menu, search for PowerShell, and select Run as administrator.
Script execution may be restricted by system or IT policies.
If PowerShell blocks the script, to unblock the downloaded file, run:
```
Unblock-File -Path "$env:USERPROFILE\Downloads\WinAppPermissionsRemediate.ps1"
```
If it is still blocked, temporarily allow script execution:
```
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
```
Run the script.
Restart the computer.
Restarting is recommended to ensure all Windows components reload correctly.
