Threads--Concurrency and Synchronization

If you distribute a Windows 9x-only INF and a Windows XP or later INF in the same folder in your driver package, the Add Hardware wizard presents both the Windows XP and Windows 9x options to the customer. The Windows XP or later INF shows up as signed, but the signed Windows 9x INF shows up as unsigned. It is not possible to determine programmatically whether an INF is a Windows 9x INF. ................
