The April cumulative update from Microsoft has brought issues not only to Windows 7 users. Certain difficulties have also arisen for those using Windows 10 (1809). According to available information, the update causes various problems due to conflicts with antivirus programs installed on users' PCs.
Reports have emerged on the Internet from users stating that after installing the KB4493509 package, the OS's performance has significantly decreased. Moreover, some users encountered situations where the operating system simply froze after the updates were installed and the reboot was performed. The OS stopped responding to any requests or processed them over several minutes. Messages from users facing similar issues appeared not only on social media and community forums but also on the Microsoft support website.
Developers of antivirus software are also working to determine the causes of the OS conflict with their products. For instance, Avast has reported that slowdowns in Windows performance may occur following the installation of KB 4493509 for Windows 10, as well as KB4493472, KB4493448 for Windows 7. It is reported that to resolve these issues, the mentioned patches need to be removed.
