Note

GAC (General Availability Channel) are non-LTSC (Long Term Service Channel) editions.

Recommended Editions

  • Windows 11 Enterprise - If you like Windows 11 features and its UI.

Win 11 GAC Download

  • Windows 11 IoT Enterprise LTSC - If you don't need the latest features and don't want to have preinstalled apps when doing a clean install.

  • Windows 10 IoT Enterprise LTSC - If you like Windows 10 features and its UI, better performance for low-end hardware compared to Win 11. Security updates continue until 2032 without any new feature updates.

More details: LTSC Information


Installation

Use the Change Edition option in the MAS Extras menu to switch between versions.

  • Select Enterprise when using a GAC edition of Windows 11.
  • HWID activation will automatically convert LTSC to IoT.

In-Place Upgrade or Repair

Keep all your data and settings while upgrading between GAC and LTSC or repairing your OS:

Clean Installation

Follow this guide for a fresh Windows installation:

Tip: Select IoT during LTSC setup if available.

Activation

  • MAS - HWID method is recommended

Telemetry Removal

Edge Uninstall

Microsoft Edge is not required; better alternatives are available.

Apps

All preinstalled apps on GAC versions can be uninstalled normally through add or remove apps or with BCUninstaller.

Clean Files

Drivers

Always download drivers from the hardware manufacturer or from the company that made your device. Windows Update also provides reliable drivers.

Antivirus

Stick with Windows Defender – it’s lightweight and effective.

  • Do not turn real-time protection off. 'Allow on device' for false positives (e.g. Cracked software).

Alternative

  • Malwarebytes - This is useful for malware scans as it has strong detection.

Disable Bing Search

  1. Open Edit Group Policy
  2. Go to:
    Computer Configuration > Administrative Templates > Windows Components > Search
  3. Double-click Don't search the web or display web results in Search (Win 11) or Do not allow web search (Win 10)
  4. Select Enabled -> Click OK.

Troubleshooting

There are many troubleshooting options within the MAS script and additional information on its site. You can also ask questions within the MAS discord server.

Tip: Use DISM before running SFC.

If you do not meet the usual Windows 11 hardware requirements, such as TPM, Secure Boot, or UEFI, you can use IoT editions which have relaxed hardware requirements while still receiving continued support in the future. Guide here: Windows 11 on Unsupported Devices

Windows 11 24H2 requires CPUs that support SSE4.2 and POPCNT instructions. There is no bypass. Check CPU compatibility on CPU-World

Additional Resources and Notes

Avoid debloaters, heavy theming, or anything else that says it will optimise or remove telemetry from your OS. This is because it will likely cause breakage to your system that is difficult to find or revert.

It is best to use starred options in FMHY System Tools - Read the warning.

Great list!
I'd recommend Microsoft PowerToys - I don't know why it's not installed by default to be honest

"It is best to use starred options in FMHY System Tools - Read the warning." This line is at the bottom of the guide, PowerToys is starred at the top of the page.

i suggest adding a small section about the oobe\bypassnro command during the first boot of windows 11 to use the local account/allow you to complete the setup without connecting to the internet

@GordonFeetman0 You can just domain join on a work/school account instead, it's a lot safer and friendlier than running commands during OOBE.

@GordonFeetman0 @waflenoob Rufus has the option to create local account which bypasses the need for an online account

Hmm I was not aware of that uninstall tool, have been using Revo Uninstaller, should I switch?

@mmupmip Revo Uninstaller is closed source so I recommend BCUninstaller

definitely should add Bleachbit to the Clean FIles section

I ran a poll in the server, majority said not to add it. I have tried Bleachbit and didn’t find it useful enough. It isn't starred in FMHY either.
