MS Virtual PC 2007 uses "known to XP" drivers but is limited in the way of hardware - No USB, Specific Hardware (no way to change e.g. Audio Device).
I can't recommend to you which Virtual Machine software to use. No matter what, this will NOT prove whether your drivers integrated properly. You can, however, look in the nLited Target Directory and/or the created ISO and see if you have a folder named "NLDRV" inside the "I386" folder. These will be your drivers you integrated. Inspect the contents to confirm that the are the same as what was in the original folders. nLite copies them into it then sets up several other INF files in the I386 folder to allow them to be "found" during Install.
for a couple of Tips on "Integration Failure".
Possibly, add the non-Dated ones last. First, select ALL non-Add-Ons (i.e. all that have EXE suffix) and IF you are integrating IE8, do NOT add those yet (or just find them and remove them, SORT the set in the nLite window, then ADD individually IE8 and THEN the IE8 Hotfixes (one by one), THEN add ALL of the Add-Ons (non-EXE suffixes). DO NOT RESORT AFTER THE FIRST SORT! This method works very well for me.
As for Italian-specific Hotfixes, I don't really know. I can tell you that many/most are "language neutral" and still use the ENU version (but are NOT ENU-specific, rather "language neutral"). Unless someone else has a "list" the easiest way is to go to each individual KB in the list, change to "Italian" and see if it offers a non-ENU file, cancel the download if it does, and copy/save the link given in that screen. This is the link that would need to be replaced in the UDC file (which is specifically for English XP).
edit - google search "OnePiece Windows XP Post-SP3 AggiornatoPack" - good luck on that! Latest version WAS (AFAIK) ... v5.7.0 (11 Aprile 2012)
