How to upload Microsoft Store screenshots for every language from Screen Studio Kit

A Microsoft Store listing keeps a separate screenshot set for each language. Eight screenshots in five languages is forty files placed by hand in Partner Center, and a file in the wrong language is easy to miss.

I make Screen Studio Kit, and version 1.5.1 adds Microsoft Store publishing to Store Sync, next to App Store Connect and Google Play. To set it up once per app you need:

• the app's Store ID and package type (MSIX, or MSI/EXE)

• a Partner Center credential file for a Microsoft Entra app with the Manager role (MSI/EXE also needs the seller ID)

• an existing listing for every language you publish

Then open More → Store Sync → Microsoft Store, pick languages and sizes, and click Run dry preview. It renders every screenshot, checks the limits (up to 10 desktop screenshots per language, one super hero image), matches languages and makes sure no other submission is in progress. Nothing is uploaded until you confirm Publish screenshots.

Publishing is part of Pro and works in the Mac and Windows versions. Your projects are rendered on your computer, with no AI involved.
