Microsoft removed about 90,000 apps from the Windows Store after app developers didn't adhere to the software giant's new guidelines. The developers had until last month to make their changes. However, many developers didn't make the requested changes and saw their apps removed.
In order to keep their apps in the Windows Store, the developers had to add an age rating to their apps.
"As part of our continuing efforts to improve the Store experience for customers, we’re bringing enforcement of the Windows Store age rating policy to published apps that are not yet rated by using the new Dev Center age rating questionnaire. We’ve identified one of more of your apps as not having a rating based on the questionnaire," Microsoft mailed to non-compliant app developers last summer.
The Windows Store currently contains 239,000 apps which is 90,000 less than the 329,000 apps the store contained last month. The removal of the apps was discovered by WindowsBlogItalia who mainly analyzed apps in Italy. It's possible the number of available apps is different in other countries because some apps are only/or not available in Italy.
