The computer encountered many strange phenomena after upgrading Windows 10 April Update

After every Windows update, many users feel confused, worried about the appearance of strange phenomena on their device. And this continues to recur with the April 10 update of Windows 10, supposedly causing the system speed to decline seriously.

Specifically, many users have reflected on their computers being suspended during login or an unusually long machine boot time after installing an update with KB4493470 number. Many users even had to completely reinstall the operating system.

According to Windows Lastest analysis, the cause of this phenomenon may be related to antivirus software of Avast, AVG, Sophos installed on computers. Even, Microsoft had to completely stop updating KB4493470 for computers that installed Sophos's Sophos Endpoint antivirus software. Before this move by Microsoft, Sophos said that it is the Microsoft updates including KB4493467, KB4493446, KB4493448, KB4493472, KB4493450 and KB4493451 new "culprits" that caused their antivirus software to malfunction.

Users of Avast on the Windows 7 platform also encounter the same error. Avira also warned that after installing the update with KB4493509 Windows 10 number, the device's speed will be reduced or Windows 7 is KB4493472 and KB4493448.

It seems that the cause of these problems for users after the April 10 update of Windows 10 is due to the scanning mechanism that anti-virus applications use to 'clash' with the management method. Service of the operating system. This means that it is not Microsoft but the antivirus software that is the 'culprit'. However, if before the release of a new update of Windows, Microsoft and anti-virus software vendors have cooperated well enough to ensure users' rights, all trouble may not have happened.
