The two operating systems use a different driver model so the Windows 7 driver won't work on Windows XP or vice versa.

The same applies to 32bit vs 64 bit - if you have a 64 bit OS you need a 64 bit driver and for the 32 bit OS a 32 bit driver.

Can I please have details? – Yetnayet Nov 21 '10 at 19:04
@yetnayet - all I'd do is use Google to find out more - I'm an application developer, not a driver developer so I don't know the details, but I'm sure that a search for "Windows XP driver model" or "Windows 7 driver model" would yield some useful information. – ChrisF Nov 21 '10 at 19:48
The details are quite technical, but in the following post a MS employee explains why they changed the driver model in Vista (Windows 7 use more or less the same model):…2800_wdm_2900.aspx. Search "Windows Driver Foundation" for details about the new model. – Alberto Martinez Nov 21 '10 at 23:29
Thank you for details. But I would like make my question clear here. My teacher asked me to Blog or Research in details if Windows XP sound driver works for Windows 7 too in vice versa as well. And in addition he asked me to explain why even if it works or not. – Yetnayet Nov 22 '10 at 13:45
@Yetnayet - I did think that this was a homework question which was partly why I deliberately left out the details. – ChrisF Nov 22 '10 at 13:52
