Download files can be restricted when you enable the GPO setting under:

 User Configuration > Policies > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Security Page > Internet Zone > "Allow file download"

You can also restrict using other browsers through AppLocker Policy since you have Win 7 clients.

The best is not to give your users Local Admin privileges.

thanks for the reply, staff need local admin rights so they run our poorly written school management software.

I was hoping for paths and filenames i can restrict to prevent chrome downloading and installing?

Well, paths and filenames will not solve your issue if the user is a tech savvy and discovers how to change the execution file name or the default path of installation. Moreover, the more you try to be restrictive the more your users become tech-knowing and the more determined to break the restrictions!

Check this thread for more information and different ideas presented - AppLocker would be very great and efficient; read through to Jason Sandys comment:

how about this, not too worried about staff renaming installers etc. but not sure of implications of blocking googleupdater.exe

Ayman BakrSenior ConsultantCommented:
Well, first you need to focus on what stage you want to put the restrictions:
1. At the download level
2. At the installation level
3. Post-Installation level

Once clear about that, then you can use the suggestion that suits your objective. GPO to disallow downloads, or GPO to disallow the installation or GPO to disallow the launch of an application that is already installed (again I would stress here that perhaps the best here is AppLocker Policy).

In the link you mentioned, googleupdate.exe restrictions will affect, not only chrome updates but any google related updates. You might want to stick to chrome_installer.exe; but if google changes the name of the file, the users will be able to download it again.

Frankly speaking, I would prefer the post-installation level restrictions because by this you avoid the hassle of changing file names rendering restrictions on the first two levels useless.

Applocker is not available for Win7 Pro which is what we have.

I would like to prevent both the downloading and the running. so maybe a SRP of *chrome.exe for the running and not sure about the downloading, any ideas what to block?

Thanks

To prevent from running chrome installation you can create a SRP of chrome.exe and chromesetup.exe with a hash rule (so that even if they change the name of the file or path, they will still not be able to run the installation).

To prevent the download you can set the 'Allow File Download' to disabled in the GPO:
User Configuration > Windows Components > Internet Explorer > Internet Control Panel > Security Page > Internet Zone

But this will diallow download of all files in that zone.

To prevent select file types or certain file downloads like chromesetup.exe I believe you'll be better equipped to have it set on your firewall appliance (cisco, juniper - whatever is your firewall).
