Windows 7 - 3 days until Automatic Activation?

hi everyone,

earlier on i installed a clean copy of windows home premium 7 64 bit.
when it prompted me to enter a product key i entered the one that's on the case of my computer(the product key is for windows 7 home premium) and when it got the desktop i went into system properties and it says "3 days untill activation. Activate Windows now."
i will now add some screen prints.




What will happen if i leave it for 3 days will it automatically activate it is a genuine copy?

thanks in advanced.

As this is a genuine copy I would personally not wait for the automatic activation to take place but would select the activate now option.

If you wait for the automatic option and something goes wrong - either at your end or Microsoft's - then it could cause you some inconvenience, such as watermarks and loss of functionality and the need to possibly call Microsoft to activate manually.

Problems are not likely but I feel it is better to not chance this

ok, thanks for your reply, i'm going to take your advice

thanks for your advice i just activated over the phone and it was successful
