Some users reporting that after installing Windows 10 KB4559309 update, their PC performance has dropped. Let’s learn what causing the issue and how to fix it.
Microsoft recently rolled out Windows 10 KB4559309 Update, also known as Microsoft Edge update for Windows 10. With this update, the company started replacing Edge legacy with Edge Chromium without user intervention.
Not only, Windows 10 users are not happy with this behavior of Microsoft but they’re also reporting that their system performance also dropped after installing this update.
One users on Microsoft Answer reported that
Since then my computer performance has absolutely tanked. my startup time is probably triple, loading any window has a few second delay.
Another user reported that
my computer is extremely slow and my external hard drive will not work. I click on something and several seconds to a minute goes by before anythinng happens. I tried to close apps using The Task Manager and got a black screen that i couldnt get out of unless I did a hard reset. I tried to uninstall kb4559309 but Windows does not allow the uninstall option. I appreciate any help to fix this.
The worst thing about this update is that you can’t uninstall it and various attempts will take you nowhere by giving error message “Update is required and cannot be uninstalled“
