**Warning : This is applicable only to the latest developer update. I meant BETA. :P
Download Chrome here:
http://build.chromium.org/buildbot/snapshots/chromium-rel-xp/
Get the latest available version.
Download the chrome-win32.zip in the latest iteration in my case it’s 14735
Unzip the files, go inside the folder (chrome-win32) and copy chrome.exe to create a shortcut for it.
Right click on the short cut and press properties.
Look for the field that says “Target” and add the ff in the end:
–user-data-dir=Profile
Double click on the shortcut and voila, a working portable GOOGLE CHROME.
