The New Year has just begun, but more Windows 10 bugs have surfaced. This time, Microsoft disabled the built-in administrator accounts, caused problems with FLAC audio, and corrupted the new sandbox feature along with the Windows Defender Application Guard.
No administrator for you
Most users did not enable the built-in feature By default, an administrator account is disabled in Windows 1
Anyone who chooses to activate is likely to expect this. It will still be there after the upgrade. However, if you update from the April 2018 update to the October 2018 update, the built-in administrator account will automatically be disabled if you have both the built-in administrator account and another administrator account enabled.
If you delete your local administrator account, you can do not gain administrator privileges for your PC. According to Microsoft, a patch is planned for sometime in January.
Where are my FLACing metadata?
According to MSPoweruser, FLAC support in the April 2018 update was already partially disrupted. But only rating music and editing metadata was flawed. You could still hear your music.
An update to October 2018 also stops this. After the upgrade, metadata for FLAC files is truncated or truncated. When you try to listen to a FLAC file in Groove Music or Windows Media Player, the first minute of the title is skipped.
The good news is that this seems to be resolved in an insider build. The bad news is that the update was not released in the October update and this is not listed as a known issue. It's hard to say when this will be fixed.
Sandbox and Application Guard Break
We really like the new sandbox feature in the latest insider build. And Application Guard is a useful security feature if you also want a locked browser.
As MSPoweruser and Windows Central have already mentioned, trust in container technology has both stalled in the same update. Microsoft has acknowledged that the cumulative update KB4483214 completely interferes with both features. It is said that the only workaround is to uninstall the update. However, you may not want to do this because KB4483214 fixes a zero-day exploit on Internet Explorer.
It seems to be very difficult to patch Internet Explorer, especially since the update has also caused boot errors for some Lenovo laptops. So if you do not use Internet Explorer – and you should not use it anyway – you can safely uninstall this update and get those security features back.
Maybe the only good news here is that it's much more minor than in the past. However, this shows that Microsoft needs to slow down and test more than treat normal users as experimental guinea pigs.
