Technical Note | October 2020

CRITICAL WARNING: With an FC-5000 unit, installing the following Optional update from

Windows Update will cause an almost immediate stop error or exception error, commonly called a Blue Screen of Death (BSoD) or blue screen, while also preventing the unit from being able to reboot properly.

Intel – System – 10/11/2015 12:00:00 AM –

TXEI driver

We highly recommend NOT to install this specific optional update from Microsoft, as it can lead to loss of any local data and software licenses on the device, requiring restoration from a backup.

If this has been installed on an FC-5000 unit, the blue screen will appear almost immediately showing a “PAGE FAULT IN NONPAGED AREA” error message. After logging the error, the system will automatically attempt to reboot. Since this update prevents the unit from rebooting properly, it will repeatedly encounter the blue screen and attempt to reboot. After the third failed attempt, the blue screen will then display “Diagnosing your pc” and “Preparing automatic repair”, which will eventually give you options to manually Restart or Advanced options.

At this point, you must select: Advanced options > Troubleshoot > Reset this PC > Remove Everything > Local reinstall > Just remove my files > Reset this PC. You may be asked to enter a local account password. If none has been set, leave the field blank and just press Enter.

This process can take some time, possibly 1 to 2 hours or more. After it is complete, the FC-5000 unit will be in a factory default state, requiring Windows setup such as following our recommendations on this web page.

You will then need to install software applications and licenses, similar to as before. Again avoid this specific Optional update. Windows Update should work fine for installing all other Critical and Feature updates. We recommend making sure our latest firmware and OS patch are installed as well from this web page.

FC-5000: Windows Updates

Microsoft Windows 10 may take a long time to boot or when performing a Restart while it is installing updates, sometimes without providing any indication that it is installing updates. The screen may be black (display backlight off), blank (display backlight on but nothing on screen), or with a blue image (with no other indicators) and may not complete for several minutes. Depending on what updates are being installed, this delay in booting can range from less than a minute to 20 minutes or more for very large update(s).

If you are wanting to avoid such a potential delay when booting or doing a Restart on the FC-5000, and your organization allows it, you could change from the automatic installation of updates to manually running Windows update. This is done under Start > Settings > Update & Security > Windows Update > Advanced options. Please note that allowing automatic updates ensures you always have the latest fixes, security patches, and features from Microsoft and is the factory default and recommended setting.

To avoid delays while booting/resuming or when wanting to perform fieldwork, Microsoft recommends that you properly set your Active Hours so downloading and installing of updates should not occur during that time.

If you want further control over downloading updates, learn how to manage automatic updates.

If you want security updates immediately, but would prefer to delay feature upgrades, learn how to use the ‘defer’ feature.
