can someone tell me what's going on here? the hard drive on my computer failed a few weeks ago. it was under guarantee so i sent it back to get a new hard drive. the other day windows stopped working so i restored it to an earlier point. since then everything is working ok but there is writing in the corner saying, this copy of windows is not genuine. also a box keeps popping up telling me to activate windows and to enter key to do so. i've entered the key but it doesn't match. so i'm guessing there's a fake windows on my computer since the hard drive was replaced. any suggestions how to sort this out?
i took it back to the shop where i bought it. it's a computer shop, they also do repairs. the guy in the shop told me when i took it back that he would get on to HP about it. i presume HP sent a new hard drive but who would install windows, HP or repair shop? i don't know.
