Symptom

Workaround

Some users who have the text size for icons set to a larger size (using Display Settings in Control Panel) may have issues launching Internet Explorer.

Reducing the text size for icons to a smaller value or using the Change the size of all items setting should lessen this issue.

Microsoft is working on a resolution and will provide an update in an upcoming release.
