Installation and Upgrade Switch to S mode in Windows 11


Windows_11_banner.png

This tutorial will show you how to switch to S mode in Windows 11.

Windows 11 in S mode is a "secure" version of Windows 11 that is streamlined for security and performance, while providing a familiar Windows experience. To increase security, it allows only apps from Microsoft Store, and requires Microsoft Edge for safe browsing.

If you have a Windows 11 in S mode edition installed, you will only be able to install apps from The Microsoft Store only. If you want to install an app that isn't available in the Microsoft Store, you'll need to switch out of S mode.

Windows 11 in S mode is only available in the Windows 11 Home edition by default.

If you switched out of S mode or just wanted to test S mode in Windows 11, then you can switch to Windows 11 in S mode on demand from any edition of Windows 11.

References:


You must be signed in as an administrator to switch to S mode in Windows 11.

S Mode requires Secure Boot to be enabled.


It is recommended to create a system image before switching to Windows 11 in S mode to avoid a clean install of Windows 11 in case you get the dreaded "Try that again" error message like below the next time you try to switch out of S mode.

Here's How:

1 Click/tap on the Download button below to download the file below.

Switch_to_Windows_11_in_S-mode.reg


(Contents of REG file for reference)
Code:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CI\Policy]
"SkuPolicyRequired"=dword:00000001

2 Save the .reg file to your desktop.

3 Double click/tap on the downloaded .reg file to merge it.

4 When prompted, click/tap on Run, Yes (UAC), Yes, and OK to approve the merge.

5 Restart the computer to apply.

6 You can now delete the downloaded .reg file if you like.


That's it,
Shawn Brink

or people like me who have to manage click happy family members LOL.

One member of my family was always messing up his pc - I installed S mode on his pc, and (touch wood) he has not messed things up since. Of course, I took his admin rights from him as well!

It does have a use for vulnerable persons (or daft persons like my family member above) e.g. parents say who want to prevent their young children getting access to more nefarious apps etc., or perhaps for elderly persons who may only want basic email, surfing, and videos.

To paraphrase Stan - "With little power, comes little responsibility"

I got an el-cheapo HP Notebook in Dec. '23 [only wanted the year of included Microsoft 365 for learning it] and switched it out of S-mode, there was a warning it couldn't be changed back except by a full/clean reinstall.

Hello Panos, :alien:

You can try to boot into your UEFI firmware settings and temporarily disable Secure Boot like in option two below to see if it will finish booting afterwards. This should switch you out of S Mode.

Here I am again, your 'Secure boot disable' option not working, final.
I'm restoring a registry backup from (14/11/24) and my system is back without any problem!
