Hotmail of Windows

In Hotmail of Windows there are two versions.

One is the CLASSIC and the other ... I forget now.

One can switch between these two at ease.

When am in one it says: (Not exact words): You are using --- version. do you find this too slow. Then use the --- version and breeze through your mails. That too is FREE.

Ok, who wouldn't like to BREEZE through mails faster ?

I switch to the other version. Don't notice any significant speed increase. The same old Model T this too.

And this too has the very same thing to say and advocates I switch to the other version (the older one) for a faster breeze through my mails.

Could this be, by any chance, the infamous Internet 'cheat' I am being advised against by all and sundry ?
