I've spent the last couple of days trying to install windows xp from a cd onto my desktop. The installtion is successful, and I can activate windows, but cannot run windows update. The error I receive from windows update is: Error number: 0x80240036 I understand that after april 2014 microsoft is no longer developing new patches, but I have presumed that customers would continue to have access to all the patches that where made up to this date. How can I install these patches? Is this possible? As mentioned, I can install windows and activate, but cannot run windowsupdate (Error number: 0x80240036). Seperately, there is an error with a windows explorer pull down menu (item) that asks: Is this copy of windows legal? How can I get rid of this message? I am not running a pirated, or illegal copy of windows and this message should not be there. I want continue running windows xp without windows update, but I need to get rid of this windows explorer error message.
