Windows Installation Info

Currently, the current compatible version of Windows 10/11 is 22H2

The recommended method to install Windows is to either install it onto the internal Solid State Drive(from a USB flash drive, or micro SD card), or connect an external Solid State Drive.

Using a microSD or USB Flash Drive is NOT recommended for running Windows.

What Exact Version of Windows Should I Get?

Typically the recommendation will be stock Windows 11 which can be obtained from Microsoft Here

What about a debloat script, or custom Windows installation?

I can't recommend a custom Windows version because of two reasons:

• Custom Windows builds that you can download violate Microsoft's re-distribution terms
• They often leave out important functionality that you may need later, or can cause un-expected issues with game compatibility, making it difficult to troubleshoot the exact issue

As an optional suggestion, you can go through this tutorial here when Windows is finished installing to de-bloat your system to your liking(The video is skipped to 9 minute marker because he just rants about Microsoft up to then) Debloat Windows 11 The Easy Way

YouTube Tutorial for Dual Boot(READ COMPLETELY)

• NOTE: This video covers all available options for dual booting (Internal SSD, External - and micro SD). For Internal, You will need at least 1 USB flash drive, or micro SD card -- it's also recommended to use mouse and keyboard, without it though you can still adjust the size of the partition using the slider, but it's less accurate:

Valve's Official Steam Deck Drivers

After installing Windows, please install all the latest drivers(except the wireless driver) from Valve. Follow all of their instructions, located here:

• Steam Deck - Windows Resources

Fix Wireless Drivers

The stock wireless drivers from Valve function very poorly, lag spikes and low bandwidth. It is highly recommended that you follow the guide here to install custom unlocked drivers:

Additional Drivers to Consider

While not officially from Valve, these are official driver updates to the hardware that is in the Steam Deck and may have better performance/stability(NOTE: If you're on Windows 11 22H2, then running a Windows Update should retrieve and install the drivers listed below as well):

• (Optional) - AMD Custom GPU Drivers by Amernime

• AMD Trusted Execution Environment(PSP Driver)
• microSD Drivers from Microsoft Catalog

(Optional)Custom Dual Boot Menu

Below is an instructional guide to using Clover or rEFInd as a Dual-Boot menu

This will let you choose the Operating System on reboot (instead of holding Volume - & Power)

Both work fine and are easy to set up.

Why would you choose one over the other?

It's a personal choice, they are both accomplish the same goal

Clover is a little more simple and less options, rEFInd has more customization options
