14 DAY TRIAL // While this month’s Patch Tuesday rollout originally seemed a very smooth one, it looks like a growing number of devices are experiencing issues after installing the latest Windows updates.
Microsoft has recently acknowledged a bug in the cumulative update KB4493509 shipped to Windows 10 version 1809 (October 2018 Update) PCs that could cause them to freeze on boot.
The company says the glitch only impacts machines running ArcaBit antivirus software and explains that it’s already working on a fix.
Earlier this week, it was discovered that the April 2019 monthly rollups for Windows 7 and Windows 8.1, along with their associated security-only updates, caused issues on machines with certain antivirus software, forcing these devices to freeze on boot.
While Microsoft acknowledged the bug and said it mostly happens on systems with Sophos antivirus software, user reports indicated that other security products were impacted too, including Avast and Avira.
Windows 10 devices also freezing on boot
Windows 10 was initially believed to be on the safe side, as the aforementioned problems were only experienced on the previous OS versions.
The software company, however, has just confirmed similar issues hitting its latest Windows release too, however claiming that only ArcaBit products are impacted.
“Microsoft and ArcaBit have identified an issue on devices with ArcaBit antivirus software installed that may cause the system to become unresponsive upon restart after installing this update,” Microsoft says.
The firm adds that a fix is already being developed, but no ETA is available right now as to when it could be pushed to production devices.
There’s no confirmation of similar problems experienced with other antivirus software, like the ones mentioned for Windows 7 and 8.1, but it remains to be seen if systems running products from different security vendors freeze on boot as well. We’ll continue to monitor user reports, so circle back for more updates on this.
