Terminal creates a UWP StartupTask, which can't be removed by normal commands. You have to block this task before App provisioning. Mount source ISO. Integrate the latest version of Terminal .msixbundle (optional). cd \Program Files\WindowsApps\Microsoft.WindowsTerminal_n.nn.nnnnn.n_x64__8wekyb3d8bbwe Edit AppxManifest.xml, and remove lines: Code: <uap5:Extension Category="windows.startupTask"> <uap5:StartupTask TaskId="StartTerminalOnLoginTask" Enabled="false" DisplayName="ms-resource:AppName" /> </uap5:Extension> Add reg entry to prevent WU from updating UWP apps: Code: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsStore] "AutoDownload"=dword:00000002 Make new ISO & install. Don't upgrade Terminal app, and this stops working if MS ever decides to patch Terminal using a CU.
What is app provisioning? So, there's no way to fix this problem on a live install? I guess it's too much work, then.
