Till now Microsoft Update Catalog site, which lets you download Windows Updates manually by searching such as for Microsoft software update, drives and hotfixes, is restricted for use in Internet Explorer only because of ActiveX Control requirement. Microsoft has announced they’ll remove the ActiveX requirement soon, which paves the way for the site to work in Microsoft Edge, Google Chrome, Mozilla Firefox, Opera and other browsers.
