NetGear, not only the proud producer of crap network cards but also creators of the worst drivers EVARRRRRRRRRR.
I noticed that I was forced to logon to my computer after installing the drivers.
Not only that, I had problems changing the options and using remote desktop.
This was more than a year ago, so details in my mind are sketchy.
The only real thing I learnt from this was that NetGear produced absolute rubbish and the only thing I should of done was not purchase their shit.
It complained about some file called mrvgina.dll and not being able to do anything about it.
(Great name for the file by the way, mr vagina)
To resolve this issue, go to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" and remove the registry key "GinaDLL"
