windows 7 home premium licence for refurbished PC's

[alanwoodward1]

Hi
I have a windows 7 HP DC 7700 pentium D Desktop PC with a licence for refurbished PC's.
I recently took advantage of the free upgrade to windows 10, and I have now decided that I would like to return to windows 7, but unfortunately I have gone past the 30 day period when I can reverse back to Windows 7.
The computer has an XP sticker with a traditional key, and a Windows 7 sticker with unusual keys.

My windows 7 licence sticker on my computer does not look like a key that I am familiar with, it is as follows;

Windows 7 home premium for refurbished PC’s
OEM Software
XXX-NNNNN
Do not tamper with or remove this label
XNN-NNNNN
NNNNN-NNN-NNN-NNN

I have a Windows 7 install disk, will any of the above keys allow me to activate my machine back to windows 7, they just don't look the same format keys that I am used to.
HELP!
Kind regards
Alan Woodward

Your key is a 25 digit code in groups of 5
