This update version will allow the pinning of up to five favorites.
    • GPU. A recent driver update to certain GPUs could cause an end user to see a blank screen upon the launch of Microsoft Edge if the end user is running version 80 and has not been updated to version 84 for existing end users, updating their Microsoft Edge browser to the latest version (version 84 or greater) will fix the issue.

The new supplemental OPK will include Microsoft Edge version 84 and the part number will be available soon.
