Microsoft Confirms Windows Update KB4493472 Issues with More Antivirus Products
Microsoft has recently confirmed that the April 2019 monthly rollups for Windows 7 and Windows 8.1 may cause systems to become unresponsive if certain antivirus products are installed.
Last week, Microsoft said that monthly rollups KB4493472 for Windows 7 and KB4493446 for Windows 8.1, along with their own security-only updates, KB4493448 and KB4493467, respectively, caused issues on devices where Sophos security products were installed.
