Does this still work?

I am thinking about buying a new computer. I currently have the Vista UPGRADE 32bit cd with a product key. I have never used the cd.

I am wondering if I can still do the work around to have a full clean install of Vista without buying the expensive full version of Vista.

Or has Microsoft put the Kybosh on this?

Here are some links showing the work around:

Please let me know if this still works.

Thanks

Yes It still work
