Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

Resolves issues that might occur with the "File Based Write Filter (FBWF)".

• KB2570814 fixes the following issues:
  • FBWFAPI by design does not allow multiple commands to be executed at the same time and it returns a clear error. The fix introduces locks in the File Based Write Filter (FBWF) Provider’s FBWFAPI calls, and all parallel requests will get served without errors returned.
  • The cache detail (changed or added files in the FBWF cache) file can be flushed from the cache in the timespan between FbwfCacheDetail instantiation and property data gathering, which results in property data gathering returning an unexpected error.
  • The event notification threshold values in FBWF are inverted.
