更新很频繁，每次更新都要提示很多应用要兼容manifest v3，必须手动重新开启
chrome canary的更新流程貌似是后台下载，新建带有新版本号标题的文件夹，运行一个特定的chromeupdatexxxx.exe，不知道要怎么阻止
下面传统阻止chrome更新的方法没用：
https://stackoverflow.com/questions/18483087/how-to-disable-google-chrome-auto-update
Have spent a long time trying to disable updates (literally hours, reading forums and testing various (some exotic) solutions), and this was driving me crazy. But there what seems an infallible solution (see further down).
Even using the official Google page with the templates did NOTHING: https://support.google.com/installer/answer/146164?hl=en
I followed scrupulously the instructions of that page, the keys in the registry are all correct, but still going to the “About Google Chrome” when the program is opened, I can see the wheel going around and a few seconds later the update is forced and done.
I have tried using the standalone installer of Google, on a Windows 8.1 machine 64Bits - and yes all the keys are set to :
Dword: AutoUpdateCheckPeriodMinutes Value: 0
Dword: DisableAutoUpdateChecksCheckboxValue Value: 1
Dword: UpdateDefault Value: 0
Dword: Update{8A69D345-D564-463C-AFF1-A69D9E530F96} Value: 0
(this last one requires the service(s) to not be disabled - gupdate/gupdatem)… both in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Update AND HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Policies\Google\Update since it is a 64-bit machine.
So the radical solution to prevent the auto-update, if that helps anyone, is to just purely sort the program responsible for the updates itself! (Just deleting it, OR saving a copy, OR renaming it OR even better just in case I one day need to do an update: Zip the content for future potential re-use).
