Now I try to Download Windows 7 Disc Images (ISO Files) , and I asked to enter my Windows Product Key (25 characters) , after I enter it , the request verification notify me -
We encountered a problem with the product key you provided. Please try again or visit the Microsoft Support Contact Us page for assistance.
Does it absolutely indicate that my Product Key is wrong or maybe this link not support all the licenses?
I found that for an arbitrary Product Key I type it give another error message -

My computer came with pre-installed Windows , probably OEM licence .
