There are frequent updates issued by Microsoft through the Windows Update features, but still, there are plenty of error codes that Windows 10 and Windows 8.1 users are getting. Here’s one of them:
windows 8 error codes

My win8 just keep asking me to activate my window,Error code: 0xC004C003 I just bought a new latop and its come with Window 8, but recently it just stated the product keys doesnt work and requested me to activate my window, i really have no idea what to do. It also stated that my product key should be on box but the window dvd doesnt came along with my laptop, please help me to solve the problem.

And here’s another complaint from one user who has some problems with the app tiles, unlike the one from above, who says he gets errors with the activation of his Windows 8 device, despite the fact that he is running a legit version. The same issue can affect Windows 10 users as well.

a while ago the windows tiles stopped working along side with the windows store and after hours of searching i managed to make the windows store open, but still the tiles didn’t work so i tried to update some apps maybe they will work then, but every time i try to update it fails and gives me this error 0x80070002. then i ignored the problem and lived without using any apps. The the update to windows 8.1 came out so i thought maybe this will solve the problems that i’m having so i started the update and everything was going fine then it hits me again with the 0x80070002 error.
