Hello Wincert forum members, I have been a long time on/off user of various versions of Windows XP (modded,and stock OEM...as a PC OS hobbyist...),and have run into a problem i was hoping some Wincert IT types could help me to successfully accomplish.... that being said,i am looking for a way to install a few 3rd party freeware (yes...freeware...not nagware,freemiumware,nor trialware)apps during the last 13 minutes or less of Windows XP GUI Mode...so would anyone one know how the syntax for nLite runonce (gui runonce??)options or another way to install my apps silently,and before windows xp setup launches XP desktop settings??? I have recently "noticed",and "noted" that Windows XP has not been supported since year 2014...and that i no longer can find the MSFN unattended XP guide online(if anyone has a "link" to the MSFN XP unattended guide in PDF format...would like a "valid" link in your reply...; ) Thanks in advance for any,all replies to this thread...

Let me preface this post by saying I am a "hobbyist"...that likes to customize windows xp os for my own pleasure so to speak... I have been having issues with nLite creating an unattended XP distribution;specifically problems of getting the nLied XP setup to run a custom new style billboard during gui-mode setup phase....I have had success(luck??),however,after using windows unattended cd creater "beta" utility getting the previous nLited XP distro to run the new style billboard screen during gui mode setup so what I need to know is which setup system files enable (or disable) the running of winntbbu.dll (or winntbba.dll...)...?_? If any IT/ techies can help me with this issue,please reply at your convenience...
