If you are still using Windows XP as your main desktop operating system, be prepared for things to get tough. Since April 2014 Microsoft has not being providing regular updates, and now more and more third party vendors are ceasing support of the platform. An excellent example of such a case is the Australian Tax Office (ATO) which says: Limited testing undertaken by the ATO indicates that whilst you may be able to prepare and lodge using e-tax 2014 with Windows XP, you may experience some problems. Which you will find at – https://www.ato.gov.au/Individuals/Lodging-your-tax-return/Lodge-online/e-tax/Computer-requirements/#OtherOS This statement tells you a number of things. Firstly, organisations like the ATO are spending less and less time to verify that their requirements are met by Windows XP. Secondly, the issues you may have are not specified. That means that troubleshooting and resolving these is going to prove more difficult and result in lots of wasted time for probably very little return. Another example is Java where it says; Users may still continue to use Java 7 updates on Windows XP at their own risk, but support will only be provided against Microsoft Windows releases Windows Vista or later.

Can you really afford that if you are running a business?
