+Scripts to build a trimmed-down Windows 11 image - now in **PowerShell**!
 <br>
 Tiny11 builder, now completely overhauled.
 </br>

-Latest Update (September 6, 2025)
-It's been a while, but a new update is here!
-
-Added removal for Copilot and the new Outlook for Windows client.
-
-Switched to a more efficient compression method (/Compress:recovery), resulting in significantly smaller ISO files!
-
-Included new tweaks to proactively block the reinstallation of certain unwanted apps.

 After more than a year (for which I am so sorry) of no updates, tiny11 builder is now a much more complete and flexible solution - one script fits all. Also, it is a steppingstone for an even more fleshed-out solution.
 <br>
 You can now use it on ANY Windows 11 release (not just a specific build), as well as ANY language or architecture.
 This is made possible thanks to the much-improved scripting capabilities of PowerShell, compared to the older Batch release.
 </br>
-Since it is written in PowerShell, you need to set the execution policy to Unrestricted, so that you could run the script.

-If you haven't done this before, make sure to run Set-ExecutionPolicy unrestricted as administrator in PowerShell before running the script, otherwise it would just crash.

 This is a script created to automate the build of a streamlined Windows 11 image, similar to tiny11.
-My main goal is to use only Microsoft utilities like DISM, and no utilities from external sources. The script has also been updated to use DISM's recovery compression, resulting in a much smaller final ISO size. The only other executable included is oscdimg.exe, which is provided in the Windows ADK and it is used to create bootable ISO images.

-Also included is an unattended answer file, which is used to bypass the Microsoft Account on OOBE and to deploy the image with the /compact flag.

 This script generates a significantly reduced Windows 11 image. However, it's not suitable for regular use due to its lack of serviceability - you can't add languages, updates, or features post-creation. tiny11 Core is not a full Windows 11 substitute but a rapid testing or development tool, potentially useful for VM environments.
 
 Instructions:
-Download Windows 11 from the Microsoft website (https://www.microsoft.com/software-download/windows11)
 
-Mount the downloaded ISO image using Windows Explorer.
+1. Download Windows 11 from the Microsoft website (<https://www.microsoft.com/software-download/windows11>)
-
+2. Mount the downloaded ISO image using Windows Explorer.
-Run the script and follow the on-screen prompts (selecting the drive letter and image SKU).
+3. Select the drive letter where the image is mounted (only the letter, no colon (:))
-
+4. Select the SKU that you want the image to be based.
-Sit back and relax :)
+5. Sit back and relax :)

+6. When the image is completed, you will see it in the folder where the script was extracted, with the name tiny11.iso

 Known issues:
-Although Edge is removed, there are some remnants in the Settings. But the app in itself is deleted. You can install any browser using WinGet (after you update the app using Microsoft Store). If you want Edge, Copilot and Web Search back, simply install Edge using Winget: winget install edge.

 Note: You might have to update Winget before being able to install any apps, using Microsoft Store.

-2. Outlook and Dev Home might reappear after some time. This is an ongoing battle, though the latest script update tries to prevent this more aggressively.

 3. If you are using this script on arm64, you might see a glimpse of an error while running the script. This is caused by the fact that the arm64 image doesn't have OneDriveSetup.exe included in the System32 folder.
