A couple of years ago, Microsoft introduced Windows 10 S in an “effort to provide a Windows experience that delivers predictable performance and quality through Microsoft-verified apps via the Microsoft Store”.
Many laptops now come pre-installed with Windows 10 S mode, including the Samsung Galaxy Book2 and Microsoft Surface Go, for example.
To clarify, S mode locks installation of apps only from the Microsoft Store, so users cannot download or install .exe apps.
It should be easy to disable, but some unlucky users have found themselves unable to escape the confines of the Store mode.
Microsoft has already established that there’s an issue, and assure us that they are working on a solution, though there’s no definitive time frame for its release:
This is not expected behavior and the issue is not with your PC. Microsoft is aware that some users are unable to upgrade to Pro Edition or switch out of S mode as a result of this blank page. We are investigating the cause and when a resolution is available the Store will update without any user action necessary.
There is no current estimate on when this condition will be resolved.
Update: Those stuck in Windows 10 S purgatory will be happy to know Microsoft has now fixed the issue, saying:
Thank you for your feedback. We have completed our investigation and have published an updated version of the Microsoft Store app which includes a fix for this issue. To install this update: From the taskbar, open Microsoft Store. Select More … > Downloads and updates > Get updates
According to Neowin, the fixed version of the store app is version 11906.1001.24.0 or later.
