A new Windows Defender update has triggered issues for IT admins, deleting Start out Menu, Taskbar, and desktop shortcuts on Windows products.

Just one consumer lifted the issue in a Microsoft neighborhood assistance thread, declaring that soon after the early morning update of security intelligence to version 1.381.2140., Defender seems to be deleting clients’ hyperlinks to programs.

Another mentioned: “..appears like that all shortcuts which are situated in ProgramDataMicrosoftWindowsStart MenuPrograms will be deleted right away”.

Broader complaints unveiled all .LNK data files were remaining automatically deleted. Some claimed looking at them all send out to OneDrive’s Recycle Bin.

“We’re investigating an issue where by customers are unable to access software shortcuts on the Start off menu and Taskbar in Windows,” Microsoft said on Twitter. “For more facts and updates, make sure you follow the SI MO497128 in your admin heart.”

Microsoft mentioned it has recognized the precise rule which was “resulting in impact” and has reverted the rule to avoid any further effect whilst it investigates more.

To fix the issue, some consumers advised that altering the “Block Gain32 API calls from Business macro” rule to audit only labored for them. Many others mentioned deleting the ASR rules, specifically 92e97fa1-2edf-4476-bdd6-9dd0b4dddc7b, also remedied the predicament. 

This has triggered a lousy working day. Need to have a resolve for restoring all the deleted icons.

Nevertheless, it remains unclear irrespective of whether right after implementing the fix, no matter if the shortcuts will mechanically return. Some buyers have experienced to manually recreate their shortcuts yet again.

“Has any individual put it in Audit manner and has the .lnk restored back again to there spot. Minimal fearful when MS fixes this, how do person get there .lnks back. Do we will need to tell all people to build them again?” wrote just one user Reddit.
