Hello,
I am new to this so I hope I have posted this in the right place...
I have just come back home after a few months aborad. PC propmpted me to download all latest windows updates on first boot.
Since that, I cannot access any windows websites like msn.com, hotmail.com or even windows update itself....
I have tried using other browser than IE (mozilla) and I get the same result.
Can anyone help ?
Thanks

Hello.

I ran into this same issue after I got some updates on an older dell I had. I was told to run the windows validation tool. Its available from Microsoft. I also had the problem on a computer that was given to me from a friend, it had a bad version of windows and they said it wasent valid. Because of that i wasent able to check my hotmail or any Microsoft websites. I would check for the windows validation tool. Let me know if this helps

Best Regards
Tim

Here is the link to validate your computer.

I will check back.
Best regards
Tim

Thanks TechTJ, I have just sorted the problem. In this case it was an issue with my router (Belkin G+ Mimo ADSL2) which for some reason did not use the correct MTU.
Had to download an update firmware update from Belkin and all is back in order.
Thanks

Im Glad to hear that.

Best Regards
Tim

Have try with Restore Point ?
Maybe it can help you
Some times i getting a failure in my Windows pdate and that is be a solutions

Nice

Most probably when you updated your Computer,the Router which was connected to it
could not recognize it since the updates change the security options and other features of
your Operating Systems and for that you had to update the firmware of the Router so that
the firmware could know the new updated settings of your Operating System.
