Upgrading a bad HDD. Can i re activate the key?

[Fliplip]

My sons PC has been running W7 HP for a few moths fine but last night the HDD started running very slowly, and W7 reported a HDD failure.
I want to put a new HDD in but cant create a disk image or back up as W7 cant read the whole drive.
So, i will re install W7 and all his apps, plus i do have a back up of the USER folder.

My question is, will i need to call MS or am i ok with just activating the new install as normal. All other hardware will be the same so i dont think ill have any problems.

Thanks.

Dave.

May require a robocall to MS but that's all. Wait until after installation to insert product key at Computer>Properties.

As long as you have the key, and its genuine, you are fine
