If you install Google Chrome, you may or may have not noticed that it installs in the Current User Profile, not for All Users. This may not be an issue if you are the only person using the Windows PC, but if there are multiple people, it is better to install it once for all. Google I believe has a Windows Installer for that purpose, but it might only be for business customers, or I have not found it.
Here is a way to installs it in the All Users Context (This is in Vista or Windows 7). I have not tried in XP.
Go to Google Pack and download the pack. Now two things:
1. If you have Chrome installed already, it will not do it, so you have to uninstall it or get it with a PC that does not have it installed.
2. You are probably going to install an older version than what you have. It seems like Google does not have the latest as part of the Pack. Not to worry, you can upgrade afterwards and it will still carry over to all users.
One more thing: You do not have to download any of the other apps, so you can just un-check them. See screen shot Oops, in there you will see Google Earth, but that is just a mistake on my part :)
3. Go ahead and download it, then install it on PC as you normally would.
4. When you are done, click on the little wrench on the top right, and select About Chrome - You will see it will automatically updated itself. See screen shots:
The original version is 8.0.555.224
After restarting, you can see the version has changed now to 11.0.696.0
Afterwards, log into the PC as a different user, go to Programs, then Google Chrome. You will see an Icon there. Once you click on it, it will start with the latest version. It will also create the shortcut on the Desktop for you.
One more thing. If you are using Google Apps (Mail, Calendar), you will not be able to use them until you have Chrome installed again. Also, I saw an error when opening my Google Mail telling me it was created with a different version, but I just follow the prompt and it all worked OK.
