Hi guys I'm new here. Have been using nlite for a while and it's a very good piece of software. Thanks a lot to nuhi. I got a problem with this new 1.2.1 version. I've done reinstall recently and integrated all hotfixes, patches and do other settings. More details please look at my attachment. But at the first boot I got this message. Windows File Protection Files that are required for windows to run properly have been replaced by unrecognised versions. To maintain system stability Windows must restore the original versions of these files. Insert your Windows XP Professional Service Pack 2 CD now. I chose ignore and keep the unrecognized version. But this message always appears everytime I install my every driver which is annoying and make me feel something wrong with my windows and I've no problem at all with previous nlite. Can someone tell me what has gone wrong please. Is this a bug in this nlite version or some other problems. After finish installing my windows, I tried to defrag my disk but always hang somewhere between 1 - 5%. Is this problem related or not? Please give me some advice. Thanks in advance.
