We have already seen this “Chrome OS” mode on Windows 8, using the “Metro Mode”. Now, Windows 7 users also can taste Chrome OS on their PCs. This time, it is not called “Metro Mode”, but “Chrome OS mode”

Officially.

You can enable this  by clicking on the Chrome top-level menu “Relaunch Chrome in Chrome OS mode”.

They did this on Windows 8 with the inbuilt metro mode feature, but on Windows 7, they had to get another workaround.  With no Metro Mode on Windows 7, Chrome actually runs maximized (or fullscreen if your taskbar automatically hides) so that users get a nice immersive experience. François Beaufort explains.

Here is how it looks like:

If you have Chrome Canary installed on your Windows 7 PC, you can go ahead and try this now.

I would really love to see someone testing this on Windows XP too. Even though they may not officially announce it for Windows XP, I have a feeling that it will work on Windows XP too. But again, that’s a guess, until I get a chance to test it or find someone who has done it.
