indicated that it can remotely disable or remove apps from end-user systems for security or legal reasons; in the case of paid apps, refunds may be issued when this is done. Microsoft initially banned PEGI "18"-rated content from the store in Europe. However, critics noted that this made the content policies stricter than intended, as some PEGI 18-rated games are rated "Mature" on the U.S. ESRB system, which is the next lowest before its highest rating, "Adults Only". The guidelines were amended in December 2012 to remove the discrepancy. On October 8, 2020, Microsoft announced a commitment to ten "principles" of fairness to developers in the operation of the Microsoft Store. These include transparency over its rules, practices, and Windows' "interoperability interfaces", not preventing competing application storefronts to run on Windows, charging developers "reasonable fees" and not "forc[ing]" them to include in-app purchases, allowing access to the store by any developer as long as their software meets "objective standards and requirements", not blocking apps based on their business model, how it delivers its services, or how it processes payments, not impeding developers from "communicating directly with their users through their apps for legitimate business purposes", not using private data from the store to influence the development of competing for software by Microsoft, and holding its own software to the same standards as others on the store. The announcement came in the wake of a lawsuits against Apple, Inc. and Google LLC by Epic Games over alleged anticompetitive practices conducted by their own application stores. With the release of Windows 11, Microsoft announced that it would not require software (excluding games) distributed via Microsoft Store to use its own payment platforms, and that it will also allow third-party storefronts (such as Amazon Appstore—which will be used for its Android app support, and Epic Games Store) to offer their clients for download via Microsoft Store. Developer tools In addition to the user facing Microsoft Store client, the store also has a developer portal with which developers can interact. The Windows developer portal has the following sections for each app: App Summary - An overview page of a given app, including a downloads chart, quality chart, financial summary, and a sales chart. App Adoption - A page that shows adoption of the app, including conversions, referrers, and downloads. App Ratings - A ratings breakdown, as well as the ability to filter reviews by
