Today is the day that Microsoft has cut support for Windows XP. As stated in an earlier post, this means that the operating system will cease to receive patches for both critical and non-critical issues. They will also cut support through their tech support hotline, but expect most 3rd party tech support companies to continue to support it for a little while.
Hopefully, you have already upgraded any workstations to either Windows 7 or Windows 8/8.1.
One point that I have not seen overly mentioned, is that if you are running Windows 7 and using XP Mode for a legacy application, the discontinuation of support in XP will also affect it. Hopefully, you have already upgraded any legacy programs from the XP days to a suitable one that is compatible with Windows 7 or 8.
Now that Windows XP is becoming a nostalgic novelty, time to add it to the virtual machine museum.
