    There are ways. 

    This is one:

    $guid =  '{26A24AE4-039D-4CA4-87B4-2F86416031FF}'
$replace = '99'

$regex = '(^.{33})..(.{3})' 

[regex]::Replace($guid,$regex,{"{1}$Replace{2}" -f $args.groups})

    [string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

    Why? GUIDs are intended to be globally unique (hence the name). If you change digits in a GUID, then it's no longer guaranteed to be unique.
