It is legal to install Windows 7 on customers computers?

Thank you for this link. I see that customer has 90 days. What happend after these 90 days? Windows blocked at 91 day or appears a note that it must be activated?

In softonic I can download Windows 7 home. Softonic offer only legal softare. So can I download this Windows (30 days trial) and install it to customer and ask them kindly to buy a license before these 30 days?

There is no 30 day trial, it is called a "Grace Period" before you must enter your product key.

If properly licensed, you have the right to use the version of the software installed
during the installation process up to the time permitted for activation.

What that mean If properly licensed?

Customer has 30 days to buy a license and active windows?

No, it means if you already have a license you have 30 days to enter the key.

That's the "Grace Period" before entering the key that you must have to use the software.

So you need to have a product key to use it, not after you use it.

So, I cannot install Windows if customer tells me that he will buy the license after 3 days for example?

I dont understand then 30 days trail what means.
You can download photoshop. try 30 days and then buy it, and Windows not. You can buy whatever program and try it for any time 1 week or 1 month and buy picense later....Windows not...
