Is there a way to prevent the "new" tag from appearing in the start menu on Windows 10 1909 every time a program is installed?
It's not currently possible. They have not implemented any method either through settings or the registry to control this feature. Currently the only ways to remove the "New" tag or to either run the app with the tag from the start menu or if you'd rather not run it by left clicking, right clicking removes it as well.
I'm not seeing any newly installed apps in your first screenshots. I missed Speccy. Is that a regedit? Because I am unaware of any methods to stop that behavior. Not that I use the default start menu anyway. Open Shell all the way!
How to turn off the 'NEW' tag for Apps/Programs recently added in the Start Menu(s) via script. Code: REM Windows Vista+ REG add "HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "Start_NotifyNewApps" /t REG_DWORD /d "0" /f >nul 2>&1 REG add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "Start_NotifyNewApps" /t REG_DWORD /d "0" /f >nul 2>&1 REM If Windows 8.x/10 add these lines too. REG add "hklm\Software\Policies\Microsoft\Windows\Explorer" /v "HideRecentlyAddedApps" /t REG_DWORD /d "1" /f >nul 2>&1 REG add "hklm\Software\Policies\Microsoft\Windows\Explorer" /v "NoNewAppAlert" /t REG_DWORD /d "1" /f >nul 2>&1 REG add "hkcu\Software\Policies\Microsoft\Windows\Explorer" /v "HideRecentlyAddedApps" /t REG_DWORD /d "1" /f >nul 2>&1 REG add "hkcu\Software\Policies\Microsoft\Windows\Explorer" /v "NoNewAppAlert" /t REG_DWORD /d "1" /f >nul 2>&1 OpenShell may use the same registry settings internally.
Most of that has nothing to do with the new tag and the first reg key is specifically what got set in windows 7 when you disabled highlighting of new programs and was not applicable to windows 10. If it works now, cool I guess, otherwise chalk it up to misimformation. Open Shell being a completely self contained implementation can change whatever behavior the developers implement.
I cover all bases for all OS's hence why those are shown, the REM statements clearly show what OS's they are for. The ones for 8.0+ do suppress the 'New' tag on the Start Menu for the newer OS's, unless m$ have suddenly altered some group edit policies and the corresponding reg entries...
Windows sure is getting mysterious with all the some stuff shows up on some systems but not on others and some hidden solutions work on some but not on others.
I ran it after creating it and it's not preventing the "new" tag from appearing in the start menu. EDIT: Tried it in Windows 10 and it's not working too.
