This is matching Device Manager Properties to DriverStore

This is the first use of italicising, in plce of coloring to indicate the match, becaus we want to retain the colour as an indication that a match was found in drivers

Code:
Sub CompareDriverFilesDeviceManagerInDriverStore() ' http://www.excelfox.com/forum/showthread.php/2408-Windows-10-and-Office-Excel/page11#post12277
Rem 0
    If ActiveSheet.Name <> "DeviceManagerProperties" Then

' Random number between 3 and 56 to get color index for any matching file names (1 is black, 2 is white , up to 56 is other colors:  3 to 56   is like  (0 to 53)+3  Rnd gives like  0-.99999  so (Int(Rnd*54))+3  is what we want
Dim ClrIdx As Long
 Randomize: Let ClrIdx = (Int(Rnd * 54)) + 3
