Steps
1. Open the GPMC
2. Create a GPO in this domain in your domain
3. Name as Google Chrome and click OK.
4. Right-click the policy you just created and click Edit
5. Navigate to the folder User Configuration\Policies\Windows Settings\Security Settings\Software Restriction Policies
6. Right-click Software Restriction Policies and select New Software Restriction Policies
7. Right click Additional Rules and choose New Path Rule.
8. In the Path field, type chromesetup.exe.
9. In the Security level drop-down box, choose Disallowed and click OK.
Repeat steps 7, 8,9 for the chrome.exe and gears-chrome-opt.msi files
Repeat steps 7, 8,9 for the path C:\Users\%username%\AppData\Local\Google\Chrome\Application\chrome.exe for Vista machines or C:\Documents and Settings\%username%\Local Settings\Application Data\Google\Chrome\Application\chrome.exe for XP machines. You should include this rule in case some of your users have already installed the browser.
After you implement the GPO and the Group Policy settings refresh on those users' local machines, they'll no longer be able to successfully run Google Chrome.
Open a command-prompt window and run the command gpupdate /force to apply the new rules.
Run the command gpresult /R in Vista SP1 or the command gpresult in XP and Vista (pre-SP1) to verify that the newly created GPO has successfully been applied.
As a final test, attempt to run the installer from the Google Chrome website. If the policy is successful, you should see the error
