Last night I received also some e-mails from 'another source' (thanks Leon \u2013 but sometimes I have to take a nap I've installed update kb4015550 on another pc and received an mrt.exe \u2013 error 0xc0000005, <\/p>\n C:\\Windows\\system32\\MRT.exe I've translated the text, because it was written in a foreign language. Update KB4015550 is causing a MRT error 0xc0000005 (Access Violation) during install. MRT obvioudly blocks installing other updates. Leon wrote within a 2nd that he had analyzed other updates (KB890830 and KB4014983) as a source of install conflicts, but at least he found the root cause. He wrote:<\/p>\n I found the cause for mrt.exe error \u2013 it was caused by update kb 890830. The odd thing is, that I only use windows defender on my machines. <\/p>\n<\/blockquote>\n It seems, that MRT is causing serious trouble. My proposal: Hide update KB890830 in Windows 7\/8.1 \u2013 and if MRT is already installed, uninstall KB890830 and block this update. <\/p>\n Leon pointed out, that update KB890830 is causing also trouble with third party antivirus software. Here are a few links pointing to forum entries with related discussion. <\/p>\n Unable to update windows malicious tool (KB890830) (Norton Forum) Something went terrible wrong with MRT update this month. Are you also facing trouble with KB890830?<\/p>\n Leon provided me with a fix: Just delete the mrt file in Windows\\system32\\mrt<\/em>. The launch Windows Update and hide the April 2016 MRT update. Afterward, restart Windows Update search 3 times again, the updates KB890830 for January, February and March are offered. Let em install \u2013 so mrt will work in those older versions.<\/p>\n","protected":false},"excerpt":{"rendered":" Microsoft has released on patch day (April 11, 2017) also a new version of Windows Malicious Removal Tool (MRT) as update KB890830.
