Hi, 

We are aware that a set of users are reporting a slow or seemingly-stuck upgrade experience when attempting to upgrade to Windows 10 or update between versions of Windows 10. The upgrade process usually takes 90 minutes or less to complete, but there is a very small subset of PCs, usually older or slower devices, where the upgrade process can take longer than typical. This situation is not related to a specific upgrade tool and has been shown to happen with Windows 10 Upgrade Assistant, Media Creation Tool, USB media, and ISO media.  

In these cases, even if the progress percentage appears stuck, the upgrade is still running. An error message should be displayed in case of actual failure. Cancelling and trying alternate methods is unlikely to improve the experience and will reset any upgrade progress made.  

We recommend the user wait until the upgrade completes before taking further action. Users can keep working as normal while the upgrade is in progress. A delay of one day would be highly unusual, but we recommend that users wait that long for the upgrade complete or to confirm there is an issue.  At that time, users should reach out to Microsoft Support or visit a Microsoft Store location so we can look into issues with the PC.

Regards

Wait a couple more hours.

If it does not respond, do the following.

Reboot, then try upgrading manually:

then try upgrading manually:

Option 1:

Download the Media Creation Tool Now

Right click the MediaCreationTool.exe file then click Run as administrator.

Note: How to verify if you downloaded or installed the Windows 10 November Update

How to create a ISO or USB drive.

Select Upgrade this PC now then click Next

Option 2:

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

then

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).
