Bought an Aspire U5-710 two weeks ago which came with Windows 10 Home pre-installed and working perfect. However, I upgraded it to Windows 10 Pro 2 days later; this was completed by Microsoft itself as my original Product-Key would not work and Microsoft had to use another. Since the upgrade however, the intel cameras would not work but gives me error code: 0xA00F4271(0xC00D3704). On checking, the drivers for the camera are working perfectly and even when I reinstalled them, they report to work ok. However, camer does not start nor can skype or anything else use it. Any suggestion/solution would be highly appreciated. Godwyns (new here)
