What rules are you referring to? You're not fully explaining what you want to know so it's hard to answer.
If you've built the PC then you're within the EULA to install and sell to the customer Builder's OEM which is then tied to that mobo. The accompanying COA sticker must be applied to the PC to signify this.
If you've only done an install during repairs or otherwise, then you'd need to install retail Win7 and provide the customer with the COA by law, and the disk as a courtesy.
Are you getting your question answered now? What is the question exactly??
It shouldn't be risky at all. If you're doing this for a customer and they're paying you for it then you should provide the COA sticker. For OEM attach it to the machine, for retail give them the packaging with COA sticker and disk.
I still don't know what rules you're asking about. But those are the ones which seem to apply.
Now we're getting somewhere.
Follow the steps in Clean Reinstall - Factory OEM Windows 7 which includes everything needed to get and keep a perfect install.
I would stick closely with the steps and ask back if you have any questions since you seem to be unclear on the basics.
