How to resolve “Windows update or other software not working”?
Resolving “Windows update or other software not working” in Syncfusion installed machine
This problem is caused by Microsoft cumulative security update 896688 and not directly by Essential Studio. Installing Essential Studio after this update will cause ActiveX controls on some systems to fail to work in Internet Explorer. Some applications that use Internet Explorer, such as Windows Update, or behave similarly to Internet Explorer, may experience these problems as well.
