On our computers, we use daily dozens of different usb drives from our customers.
This is bad because the registry hive is becoming huge as windows is so "smart" to save them forever
devmgr_show_nonpresent_devices=1 and i saw thousands of usb flash drives
There is a software that will automagically delete all previous devices?
Also this will solve a lot of problems with scanners and printers that will be seen as another device just because the user has plugged in another usb plug
