Since I 'upgraded' my Microsoft browser to IE10, I have not been able to access the internet using this browser, and my Firefox alternative browser has also stopped working. I simply get a message on both browsers to the effect that they cannot connect with the proxy. I am using an Ethernet cable between my computer and router. I have checked connections. Although I cannot connect via my browsers all other activity requiring internet access (Kindle, Laptop, email on this computer using Outlook, updates etc.) appear to be working correctly. I have done numerous System Recoveries with mixed results. If I go back to before IE10 was installed the recovery fails. If I do a recovery to a recovery point after installation then I get a message that the recovery was successful and all appears well until I switch off the computer and power back up later. Upon re-boot I am no longer able to access the net. If I then do another system restore to the first available restore point then once again the browsers work, which is why I am able to send this message. When trying to restore further back the exercise fails and I receive the following - - - unspecified error 0x800700b7.
Any help would be appreciated.
