Frequently Asked Questions

WoR application

Why does the installation process keep failing?

Please check that:

you're using the latest version of WoR
your SD Card / USB drive are not failing (try with other hardware)
your anti-virus solution doesn't interfere with the deployment process

If it fails at the Installing drivers stage, then there's an issue with the version of DISM on your PC. In this case, you can either:

update the version of Windows on your PC
select an older image in WoR
tell the tool to use a custom version of DISM.

If you want to do the latter, you'll first have to download and install a copy of the Windows ADK, then add the following path: adkInstallPath\Assessment and Deployment Kit\Deployment Tools\ARCH\DISM to the settings.ini file.

Replace adkInstallPath with the path where you've installed the ADK. (it's C:\Program Files (x86)\Windows Kits\10 by default)

Replace arch with the architecture of your machine (amd64, x86)

If the problem persists, please click on the Where can I report issues? item below.

Where can I report issues?

We have an issue tracker page just for that.

Make sure to attach the latest/relevant *.log file from the logs directory of WoR. (you can sort them by modified date in Explorer)

General

Where can I find Windows images?

See the Getting Windows images section of the Downloads page.

I want to update a device driver without reinstalling Windows. What should I do?

I've wrote a small tool for that purpose: Download here

Manual method:

Mount the SD card on a Windows 10 desktop PC
Launch Command Prompt as Administrator
Type Dism /Image:WINLETTER: /Get-Drivers
Choose the device driver that you want to update (e.g. OEM1.inf)
Type Dism /Image:WINLETTER: /Remove-Driver /Driver:OEMx.inf
After the driver has been removed, type Dism /Image:WINLETTER: /Add-Driver /Driver:PATHTOINF

WINLETTER = the Windows partition letter on your SD card (e.g. F)

OEMx.inf = the device driver that you want to remove, where x represents its number

PATHTOINF = path to the new driver (e.g. C:\WindowsPi\drivers\rpiuxflt\rpiuxflt.inf)

If you want to install a new device driver (not to update an existing one), you can follow the steps above but you don't have to remove any driver.

Why am I getting the 'Windows Setup could not configure...' error?

The "Windows Setup could not configure Windows to run on this computer's hardware." error usually occurs when the power was interrupted during the first boot process.

This can be fixed by re-installing the image.

Does the built-in Wi-Fi, Bluetooth, (insert device here) work?

You can find the current hardware support status here: https://github.com/worproject/RPi-Windows-Drivers#status

And no, we don't have an estimated time of arrival (ETA) for anything.

Why am I not able to use any USB devices?

Some outdated guides may tell you to use winpatch. This is no longer required and will break the USB driver.

I keep getting the 'Why did my PC restart?' screen. What should I do?

We don't currently know the exact cause of this issue, but we've seen it happen on slow SD cards / USB drives. So make sure to try a faster storage drive.

Note: sequential speeds don't matter as much as random I/O ones do.

Why drivers that work on my PC don't work on the Raspberry Pi?

Your PC most probably has an x86 Intel/AMD processor, while Raspberry Pi has a totally different CPU architecture.

The x86 emulation layer in Windows 10 is only available for user mode applications, not for drivers.

Only ARM64 drivers are supported on Windows 10 ARM64. The same goes for ARM32 builds.

Can I run x86 apps?

Yes, you can run most x86 apps on Windows 10 ARM64 (x64 support may come in a future version of Windows).

Why (insert application name here) doesn't work?

Some apps may not work as expected, and we can't really do anything about it. Please contact the app developer / hardware vendor for support.

Is this project legal?

Yes, it's perfectly legal.
