Basically, you get a 404 error if the page you are looking for isn’t on the website’s server any more. You can get the error in two ways.

Fix Windows Update KB3004394

There’s nothing glamorous about a designation like KB3004394, but that doesn’t mean you shouldn’t be concerned with it.  It’s a Windows Update that’s been released recently (Black Tuesday) and sad-to-say it’s been causing some problems … but only on certain computers. This update is affecting machines running these operating systems:

  • • Windows 7 Service Pack 1 (SP1) x86      (32-bit)
  • • Windows 7 Service Pack 1 (SP1) x64      (64-bit)
  • • Windows Server 2008 R2 SP1.

What’s the Problem?

Because Windows Updates often address several issues at once, this particular update could have various results.  The most common though is that – gulp – the update is negating your license so Windows is telling you that it isn’t activated; that you’re version isn’t genuine!

Other issues include:

  • • Various UAC (User Account Control) prompts that say weird things
  • • Windows Diagnostic Tool error 8000706f7
  • • An inability to install the AMD Catalyst driver
  • • Windows Defender error 2147023113

The Check

system_properties1If you’re not sure whether your system is one of the affected ones or not, find Computer in Windows Explorer and right-click it.  Then choose Properties.  The properties box will open showing you what version of Windows you have installed and whether or not you’re using a 32bit or 64 bit computer.

It’ll also tell you whether or not your version of Windows is properly registered.  If you haven’t received any alerts about your Windows Activation, or you haven’t experienced any other problems, you probably don’t have update KB3004394.  But it’s still a good idea the check here and make sure every thing is set right.
