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..

want to block chrome from receiving connections from google? check the os x firewall. it can stop any app from receiving connections other than the ones you initiate. in others words, your web browser will work the same.
