If you are using MS Edge and find yourself trying to upload documents but the dialog box does not upload or cannot be cancelled or dismissed, then you will likely need to update your browser. Just follow the instructions laid out below to do so.
How to update Edge
This guide will step you through the process of updating your Microsoft Edge web browser.
Keep Edge up to date by keeping Windows 10 up to date
Updates to Edge are automatically installed when Windows 10 is updated. So to keep Edge up to date, you need to keep Windows 10 up to date.
Windows 10 automatically updates itself
Microsoft Windows 10 will periodically check for updates and install them. This will automatically mean that you have the latest "stable" version of the Edge web browser.
This guide will show you how to manually trigger Windows 10 to check for updates and install them if they are found.
Windows 10 will connect to Microsoft and check for any updates.
If they are found, they will be installed and you will get the latest version of Edge.
Congratulations, you have now ensured that your copy of Windows 10
(and thus Microsoft Edge) is up to date.
