My opinions about curated app stores has not really changed. Do not give up platforms, such as Win32, that allow you to publish without the approval of one or more organized bodies. Even if the company doesn’t use it to suppress content that they don’t like now, they might in the future and governments might even force them to.
I’m not exactly sure when this happened, but NVIDIA has a version of their Control Panel software on the Windows Store. The screenshots show that they are running the 397.64 Game Ready drivers on a pair of 1080 Tis, which would suggest sometime after May 9th. It is the typical control panel that we’ve known and used for probably around fifteen-plus years now. The app does not include GeForce Experience or anything like that. Beyond helping devices that cannot run Win32 software, needing to rely upon Windows Store and Windows Update, it demonstrates two things. First, it is another example of a Win32 app that was packaged into a Windows Store app. Second, it shows that apps can still have access to drivers and other low-level things.
One last funny note: the system requirements do not specify that your GPU needs to be from NVIDIA.
