Windows Update thought I was running a Mac

I got the above error message (This website is designed to work with Microsoft Windows operating systems only) when trying to run Windows Update. A Mac, really?. To fix the issue, and get Windows Update working again I deleted the following two registry keys:


[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Internet Settings\5.0\User Agent]

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\
Windows\CurrentVersion\Internet Settings\5.0\User Agent]


Once deleted, I rebooted the computer and all was working again.
