"We have updated several thousand bios using SCUP and the Dell Catalog - as always, test test test. . . "
"I checked with our team - they shouldn't be there - check to see if those old bios appear in SCUP - if they are in SCUP, check to see that Expire=True - once Expire=true, you can re-publish updates to wsus, then run your synch in ConfigMgr - that should make them disappear.Greg"
