Hi Christian,

A faulty driver can render your printer inoperable, or your display invisible. That’s why Microsoft will likely attempt to warn you before making the upgrade, either through its Get Windows 10 app or with error code 0x800F0923.

There are two ways to fix this issue:

Fix 1. You should be able to identify driver problems with help from Microsoft’s Get Windows 10 app. To open the app, click the Windows icon in the bottom-right corner of the screen. Then, click the menu button, and click Check your PC. This will list any drivers or applications that aren’t compatible with Windows 10.

In File Explorer, navigate to the following file:
C:\ $WINDOWS.~BT\Sources\Panther\Setupact.log

Within Setupact.log, you should see a list of logged errors, each showing the file name and directory of any problematic drivers.

Once you’ve identified a troublesome driver, you can check for updates that will enable you to get Windows 10.
Microsoft recommends updating drivers through Windows Update.

1. To do so, click the Start button, type Update, then select Windows Update.
2. In the left pane, select Check for updates, and then choose the ones you want to install.
3. This menu will tell you whether each update is important, recommended, or optional.

Microsoft may not be able to find and download new drivers automatically, in which case you must visit the device manufacturer’s website to look for updates yourself.

Fix 2. If the above method don’t work, and you still want to upgrade to Windows 10, you can try deleting the problematic drivers before proceeding with installation. You can attempt to reinstall the drivers from within Windows 10.
Keep in mind that while drivers are uninstalled, you won’t be able to use the devices they are tied to. Uninstalling graphics card drivers, for instance, may lower your screen resolution and limit video performance. If you can’t restore these functions after installing Windows 10, you may have to roll back to your previous Windows version.

I hope this helps.

Lokesh
