The user interface of the new Metro will make Windows 7 a completely different experience for XP, Vista and 7 users, but especially will challenge the people who use a desktop PC. Why? Since we are accustomed to Windows 8 mouse input and emphasize the touch. The Metro is more sui for touch than the mouse.
So, how can desktop users today, preparing for when they are later upgraded to Windows 7? I’ll tell You.
If You are running Windows 7, maybe your computer will run Windows 7
From everything we have heard so far, it seems that if your computer currently has Windows 7, then it must be able to run Windows 7 without problems. After working with the Windows 7 Preview build a bit, as much as I can tell you this: a key component of your system will be very important and that’s your hard drive.
When I install Windows 7 to one of my desktop that is running Windows Vista, I don’t want to bother my current operating system, so I decided to just disconnect the hard-drive (SATA drives) and install another drive into the Bay of removable drives for Windows 8. I just got a spare IDE drives so I use it, which will be slower than the original SATA drives in my computer. The whole system is fine, because I recently had an upgrade worthy of a CPU Pentium D dual core processors for up to 2 gig of RAM (mostly Windows 7 PC must have a lot of memory and a decent CPU for Windows 8).
