  • Editing or creating policies for AppLocker can cause the MMC snap-in to crash when generating rules for a packaged app.
  • After upgrading the OS, the AppX database may end up having corrupted entries, which will cause issues with components that use them.
  • The size of a file according to NTFS and a stream control block, and the Cache Manager may become out of sync which will cause a bugcheck if a read operation is attempted out of bounds for the file size that Cache Manager has stored.
