How to disable "To get future Google Chrome updates, you'll need Windows 10 or later" startup warning on portable Ungoogled Chromium?

Question

To disable "To get future Google Chrome updates, you'll need Windows 10 or later" warning on Google Chrome, we know that it's by setting HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome "SuppressUnsupportedOSWarning" REG_DWORD to 1.

But its said not to work for portable editions and for sure for Ungoogled Chromium portable editions. There seems no online help on this.

chrome://policy/ with "Show policies with no value set" checked shows the SuppressUnsupportedOSWarning option as not set, but there is no means to change it there. (the string is from chrome.dll)

How to get rid of this warning on Ungoogled Chromium portable?

Answer 1

After having made some registry tries, inspiring from the one that works for googled-chromium, it turns out that this works:

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Chromium]
"SuppressUnsupportedOSWarning"=dword:00000001

So instead of "Google\Chrome" key, using just a "Chromium" key (after the name that appears in the "about" box).

Now chrome://policy/ shows the SuppressUnsupportedOSWarning option set to true. So even a "portable" version checks the OS registry for that.

Back here in 2023! Writing an update for anyone that still fields calls from relatives running older versions of Windows.

Run cmd.exe as administrator, if you can't find it...

• Open My Computer > C > Windows > System32 > cmd.exe
• Hold shift, then right click on cmd, run as administrator

Then copy this, right click in the cmd window, paste, enter.

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome" /v SuppressUnsupportedOSWarning /t REG_DWORD /d 1 /f
