I have a Dell Dimension C521 desktop running XP and using Outlook Express as my email program. Upgrade to Windows 8 a good idea????????

That's why I suggested installing the download (you don't need to purchase a product key) and try Windows 7 before you buy.

The image backup will allow you to re-install XP if Windows 7 isn't fully supported.

Thanks for the information - seems to be much to be considered.

There is a lot to be considered when Upgrading an Operating System.

That is why Microsoft also supplies this Windows 7 Upgrade Advisor that I put in my earlier reply.

Run the "Windows 7 Upgrade Advisor"

As newer Operating System come out, the Hardware requirements to run them increase dramatically.' especially going from XP to Vista/Windows 7 (namely RAM and Graphics Hardware, just for starters)

Cheers.

I was afraid of something like that; so glad I asked.

Thanks for the info.

You are welcome.

Make sure you follow my Windows 7 Compatibility tests on your XP before doing anything with Windows 7.

Cheers.

There are NO Windows 7 Drivers available for your Dell Model Deskttop.

So be very careful about buying Windows 7.

Before you even "looked" at Windows 7, read and follow all of these instructions:

Go to your Computer / Laptop Manufacturer's website and see if Windows 7 Drivers are available for your Make and Model Computer / Laptop.

If not available, Windows 7 will not work correctly for you.

There are NONE available.

Run the "Windows 7 Upgrade Advisor"
