I have a mini pc that came with a pre-installed windows xp embedded. Problem is that I want to change a regional settings( so I can have a 24h datetime and so on...) but everytime I change it to what I want I am getting a box that I need to accept so it can restarts. When PC restarts regional setting are the same.

How to make this to save settings as permanent ?

Does the mini PC have a hard disk with Windows installed on it or is the OS installed in ROM? – martineau Aug 31 '12 at 16:45
It has a ssd drive which has windows installed. Do I need to install new version of win xp to make this work? Or there is some workaround solution? – user123_456 Aug 31 '12 at 16:47
Sounds like the SSD is getting a fresh copy of the OS from somewhere every time you restart. – martineau Aug 31 '12 at 16:59
It was resetting everything at the beginning then I started one script which turn off system settings now I can use it normally except that regional settings are always restarting – user123_456 Aug 31 '12 at 17:06
A workaround might be to identify the registry settings you're changing using the Regional and Language Options and export them in regedit to a .reg file. Afterwards you can create a batch file that merges those setting back in and have the script executed at startup by putting it in the Startup folder. – martineau Aug 31 '12 at 17:11

Most likely what you are running into is XP Embedded's Enhanced Write Filter (EWF)

Enhanced Write Filter (EWF) provides the ability to write-protect a run-time image. By redirecting all write requests to either a separate disk partition or RAM, EWF allows the run-time image to maintain the appearance of a writeable run-time image. Additionally, Enhanced Write Filter provides the ability to deploy a run-time image onto read-only media, such as a CD-ROM.

You can turn it off using the EWF Manager Application (if it was included in the Embedded image).

To start the EWF Manager run Ewfmgr, and use it to get status, enable and/or disable the EWF, etc.

More info from MS here: Using the Enhanced Write Filter (EWF) in Windows XP Embedded

This PC is actually preinstalled as a thin client so I have started a .bat file which says "Turn off system protect". Is that what I needed to do? Where do I find that Ewfmgr – user123_456 Aug 31 '12 at 16:59
Yeah most likely that batch file will run it for you. Why not open the batch file in Notepad and look at it? :) Usually you unlock, reboot, make changes, lock it, and reboot again. Have you tried just running Ewfmgr from a command prompt or the "Run" dialog? – Ƭᴇcʜιᴇ007 Aug 31 '12 at 17:14
this is what is inside the file EWFMGR C: -COMMITANDDISABLE shutdown -r -f -t 01 but it has an error when executing. I think it can't find ewfmgr – user123_456 Aug 31 '12 at 17:33
Well since I can't see the error from here, what was it? :) Again, Have you tried just running Ewfmgr from a command prompt or the "Run" dialog? You should really hit up the links I put in my answer, as XP Embedded is not the same as a usual XP install you need to do some studying. ;) – Ƭᴇcʜιᴇ007 Aug 31 '12 at 17:36
