Close it then do the following:

Run the Windows Update Troubleshooter:

Restart then try again. If that does not work, try upgrading manually:

Pre-requisite Task

When making significant changes to your computer such as updating the operating system, you should always backup. See links to resources about backing up by clicking the link for the respective version of Windows you are running: Windows XP, Windows Vista, Windows 7, Windows 8/8.1

• How to manually backup and restore your files
• How to free up disk space in Windows
• How to: 10 Tips before installing Windows 10
• How to: Determine if an application or hardware device is compatible with Windows 10
• Will documents and apps remain, or are app installs required

then

• How to download official Windows 10 ISO files
• How to: upgrade from previous versions of Windows using Windows 10 ISO file

then

• Disable (preferrably uninstall) your Antivirus utility before attempting the upgrade.
• Restart a few times then try again.
• Disable General USB Devices (example - Smart Card Reader). 
• If you are using a SCSI hard disk, make sure you have drivers available for your storage device on a thumdrive and it is connected. During Windows 10 setup, click the Custom Advanced Option and use the Load Driver command to load the appropriate driver for the SCSI drive. If this does not work and setup still fails, consider switching to a IDE based hard disk.
• Perform a clean boot, restart then try again.
• If you are upgrading using the .ISO file, disconnect from the Internet during setup, if you are connected by LAN (Ethernet) or Wi-Fi, disable both then attempt setup again. 
• If you are updating through Windows Update, when the download reaches 100% disconnect from the Internet LAN (Ethernet) or Wi-Fi then proceed with the installation.
• If that does not work, try using the .ISO file to upgrade if possible.
• If you are connected to a domain, switch to a local account.
• If you have any external devices attached to the machine, disconnect them (example, gaming controllers, USB keys, external hard disk, printers, non-essential devices).

This is not my idea.  I read it elsewhere in one of the postings.  Not sure where.  But it works.  You need to go into Services and STOP Microsoft Update.  It is trying to run at the same time that Getting Updates is trying to get additional downloads.  So, there is a deadlock between the two applications running at the same time.  By STOPPING Microsoft Update, it kills the deadlock and allows the Getting Updates of the Windows 10 installation to complete, in a matter of seconds or minutes depending on where you are.  There are other posts that talk about this and it definitely solved my problem and I was able to get a successful installation after the Windows 10 install completed.  It takes roughly 1-2 hours to complete.  You may have to STOP Microsoft Update several times during this stage of the installation.  Because once you STOP it, it will try to restart the service.  So, you may have to do this a couple of times in the Services.

Thanks Bob, this worked for me. My update was stuck on "Checking for updates" with not even a percentage value and stopping the "Windows Update" service unblocked it for me and it progressed.
