I managed to find a way to completely stop google chrome from auto

updating itself and you can still re-enable it to update when needed.

Just follow the steps below:
1. First, you need to find where the google chrome updater is located
(they keep on moving it every once in a while), you can either search
for it with windows search or you can right click on the google chrome
shortcut then hit “properties” and on the shortcut tab hit “Open file
location” the “Update” folder usually is in the google folder just 2
folders back from the location of the google launcher where the
shortcut will bring you.

2. Make a backup/archive of the “Update” folder using winrar or any
similar application you prefer.

3. Delete the “Update” folder (I’m not sure if you need to close chrome
first, but to be sure just close any running google application first
including the updater from the task manager if you can.).

4. Open chrome, then hit on “The Generals” Button?? which is the former
“wrench” icon. and click on the “About Google Chrome” button from the
drop down to see this “Update failed (error: 3)” which will verify that
the updater is no longer working.

Then, in the case that you need to update chrome again just extract the
“Update” folder from step 2 in its proper location (so, make sure that
you note where that is before deleting the folder) and you will be able
to update google chrome again.

Sorry the english,
Goodluck..
