@gexecuter:
Depends. Those files can be useful if you add hardware through the Windows Device Manager. This is not the way common users would want to take when installing their hardware after (re-)installing...but if you are a power user (a bonafide registered one instead of thinking so!
) this method can prove quite useful.
Then again, the freeware that is suggested earlier in this tread makes life easier. Personally the Management Console charms me a lot more than the interfaces those backup-software forces on me.
