Techies are reporting that Microsoft Defender for Endpoint attack surface reduction (ASR) rules have gone haywire and are removing icons and applications shortcuts from the Taskbar and Start Menu. The problems were first noted early today, Friday 13th, by multiple IT folk and many seem to be scratching their head as to the cause. Some said they are experiencing it on both Windows 10 and Windows 11."I noticed it at around 8.45am (UTC)," one techie at an independent software shop told us. "The ASR rule is removing icons on the taskbar and Start Menu and in some cases uninstalling Microsoft Office as well." ASR is designed to make a PC safer by blocking macros etc, but the clean-up is certainly more dramatic than expected. "It just happened, we don't know what caused it. "We suspected it was a KB – a patch from Tuesday – that went wrong but I’ve spoken to plenty of others this morning and we think it is definitely related to the ASR rules."

Happy Friday 13th sysadmins! Techies find workarounds but Redmond still 'investigating'
