chrome “Managed by your organization”

Problem:

There is this weird message on chrome, saying

and at chrome://management, it says

turns out, this is due to some deprecated extensions.

Solutions:

To sort out the issue, on Windows, go to regedit, then search for any suspicious chrome registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome
HKEY_CURRENT_USER\SOFTWARE\Policies\Google\Chrome

for my computer, there is this deprecated EnablePluginPolicy, and with registry of AliSSO and AliWangwang.

After clearing these registry, and restarted chrome. The weird warnings are all cleared.

chrome://policy/ is clean
