Windows Updates Break Administrator Account, FLAC Audio, and Windows Sandbox

The new year has barely begun, but more windows 10 bugs have popped up. This time Microsoft has disabled built-in administrator accounts , caused problems withFLAC audio, and broken the newSandbox featurealong with Windows Defender Application Guard .

No Administrator For You

Most people haven’t enabled the built-in Administrator account at all, and it is disabled by default in Windows 10. So, as MSPoweruser notes, this only affects you if you’ve gone out of your way to enable that account.

Anyone who’s chosen to enable it probably expects it will still be there after upgrading. But, as explained on the Microsoft Taiwan blog , when you upgrade from theApril 2018 Update to theOctober 2018 Update, the built-in Administrator account will be silently disabled if you have both the built-in administrator account activated and another administrator account present.

If you delete your local administrator account, you wouldn’t be able to gain administrator permissions on your PC. Microsoft says it plans a patch for sometime in January.

Where’s My FLACing Metadata?

According to MSPoweruser , FLAC support was already partially broken in the April 2018 Update. But only rating music and editing metadata was broken. You could still listen to your music.

Updating to the October 2018 puts a stop to even that. After taking the update, metadata for FLAC files will be truncated, or cut off. When you try to listen to a FLAC file in Groove Music or Windows Media Player, the first minute or so of the track will be skipped.

The good news is that this seems fixed in an Insider Build . The bad news is the fix hasn’t been brought to the October Update, and this isn’t listed as a known issue. So it’s hard to say when this will be fixed.

Sandbox and Application Guard Breakage

We really like the new Sandbox feature in the latest insider build. AndApplication Guard is a useful security feature if you want a locked down browser, too.

Unfortunately, as pointed out by both MSPoweruser and Windows Central , their reliance on container technology brought them both down in the same update. Microsoft has acknowledged that cumulative update KB4483214 breaks both features entirely. It says the only workaround is to uninstall the update . But you might not want to do that because KB4483214 patches a zero day exploit for Internet Explorer.

It seems like a lot of trouble to patch Internet Explorer, especially since that update also caused booting failures for someLenovo laptops. So, if you aren’t going to use Internet Explorer―and you shouldn’t use it anyway―you can safely uninstall this update and get these security features back.

Perhaps the only good news here is that these are much more minor bugs than in the past. But this shows that Microsoft needs to slow down and test more, rather than treating regular users asguinea pigs forupdate testing.
