Microsoft has created problems for system administrators with the latest Patch Tuesday update after one of the fixes exposed drives that were supposed to be hidden.
IT workers on Reddit and Microsoft support forums complained that MS16-072 patch was causing the problems.
The original poster on Microsoft Technet said: "I installed Windows patches last night and this morning found out that there were a number of issues with my GPOs [Group Policy Objects]," they wrote.
"Example: desktop image would not show up. A, B, C and D drives that were meant to be hidden from users are now showing up. When I uninstalled this update and rebooted, everything was back to normal."
As the user noted, and many others on Reddit, the problems can be fixed by simply removing the update, but it's an embarrassing situation for Microsoft's Update process which has already seen multiple instances of security updates that have caused machines and even networks to crash.
Sysadmins have had to fight to be heard in their demands to have more granular control over the installation of updates in Windows 10, which was initially going to be limited to unseen automatic updates.
Worse still, Microsoft has been caught hiding its GWX adware inside security updates, which is pretty low.
The fact remains, however, that the sheer number of 'me too' cases across Reddit and Technet proves that this patch wasn't tested properly, and that will concern the people who put their trust in Windows to run their business.
Microsoft has flagged the problem as 'Important' and will release a fixed version in due course.
