Building Tiny11 Yourself
Using only open source .bat scripts by NTDEV and official files downloaded from Microsoft
Build with https://github.com/ntdevlabs/tiny11builder (video tutorial by NTDEV), but do NOT use the oscdimg.exe as the signing is missing a proper timestamp. Always use official Microsoft tools from their website.
oscdimg.exe is included in the Windows ADK Package located @ https://learn.microsoft.com/en-us/windows-hardware/get-started/adk-install
During installation of Windows ADK, you only need to tick the part of the package called "Deployment Tools" to get the file.
After it's installed, you can find oscdimg.exe here:
C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\Oscdimg
