Microsoft has announced it has revised its policies regarding "misleading" apps in Windows Store, resulting in the removal of 1,500 fake apps from the store.

The company modified the Windows Store app certification requirements with three key changes. First, apps need to be named in such a way to "clearly and accurately reflect the functionality of the app."

Furthermore, apps need to be categorized "according to the app function and purpose," and finally, the app icons must not be too similar to those of other apps.

Microsoft claims that "most" developers of the apps already in Windows Store have agreed to comply with the new rules. Some did not, which is why the company removed some 1,500 apps from the store.

Microsoft says it will refund the cost of an app that was downloaded because of a misleading title or description. Also, the company says it is working to speed up the app review process, and it's encouraging users to report problematic apps using the "report concern to Microsoft" link in Windows Store.
