for one thing I would be careful of is that if you cross over your templates and use a EDU template your work file will now be stamped as EDU\Student and may cause big probelems for work.
it would be better for you to have 2 seperate PC's one for work and one for school!!
but if you want to have both, you would have to go into the reg file and keep changing between the 2, big pain.
last but not least SW 2013 doesn't run on XP, SW2012 was the last to do that.
You might consider dual-booting 2 copies of Windows, one for each Solidworks.
