My PC is running Windows 10 in S mode which run only apps frome the Microsoft Store. I tried to find out if Arcgis and Arcmap are available. Only a basic Arcgis app is there, but not the desktop version. I am wondering if ESRI can develop the full Arcgis Solutions including Arcmap and launch them in the Microsoft Store.
With ArcMap already in its last available version, no further development is expected.
With ArcGIS Pro also, I don't see any such update in its RoadMap.
The only way I can see ArcGIS Desktop work, is to switch out of S Mode. Check with your IT team, if that is possible, since you won't be able to turn it back on.
Alternatively, You may choose to use a different machine (Standard Windows 10), if available.
