Hello !
I was using a licensed version OS win7 ultimate on my old system.
Now after upgrading the system (mobo, processor changed) it prompts me to purchase a new product key.
I found that after a major up gradation using the the same product key violates the user end agreement and so I left it there and I purchased a Home premium .( Somebody suggested to convince MS about the up garadation but didn't try it)

Now in the new sys win 7 ultimate sp1 is running and i have to change the product key within 30 days.
My query is- Can I downgrade to Home premuim without a clean install ? Any workaround solutions ?
Thanks in advance.
 
So, it sounds like you were using an OEM version of Win 7 Ultimate and the system prompted you to re-activate (or buy a new license). I would recommend you perform a manual activation (call the number provided). MS is pretty good about allowing you to do so, just tell them you had to replace your motherboard and that you only have the OS installed on the single system.

If successful, you can return the Home Prem license (if unopened) or save for another use.

There are ways to change the product type and downgrade your install, but that would not be advised. A clean install is the better way to go.
