On Tuesday, April 8, 2014, Microsoft will no longer be supporting Windows XP or Office 2003, which means they will not be releasing updates which guard against known virus and malware attacks.
If you continue to use Windows XP after support ends, your computer will still work but it might become more vulnerable to security risks and viruses. Also, as more software and hardware manufacturers continue to optimize for more recent versions of Windows, you can expect to encounter greater numbers of apps and devices that do not work with Windows XP.
You may have some defense if your company has an effective firewall or if you are running a current version of an anti-virus program. However, for business, replacing your computer with one running Windows 7 or 8.1 is highly recommended.

If you would prefer to literally hear about it, the end of XP was covered in an episode of Spark with Nora Young on CBC. http://www.cbc.ca/spark/blog/2014/03/30/windows-xpiry/ (10 minutes in length)
Please contact your IT professional to help with upgrading or replacing your computers. Once a new system is in place, I can easily connect remotely to set up BusinessVision in a short period of time. In my humble opinion and based on the distress calls I get when others try to install BV, it is worthwhile to have me do this work for you.
