When using a Windows Embedded Standard 7 or Windows Embedded 2009, any changes you make on the device are not saved and are lost upon device reboot.
Within Windows Embedded technology there is a system called Enhanced Write Filtering. EWF as it is also known deploys a RAM based overlay in which all the write operations to the SSD you make are stored. This is to protect the SSD from being written to by both users and viruses alike. All data written to the overlay is lost on boot or power cycling.
When an administrator wishes to make changes to the settings of the OS or any software accompanying the OS, they need to follow the steps outlined below:
- Log in as the Administrator user
- The easiest way to do this is to let the device login to the user desktop, click logoff keeping the <SHIFT> key pressed whilst the logoff is taking place.
- You will then see the administrator login prompt.
- The default password for Administrator is Administrator
- Make the changes you wish to the OS
- Click the START MENU
- Select the CONTROL PANEL
- Select ADMINISTRATIVE TOOLS
- Select Write Filter Manager
- Select Commit Changes to Disk and click on OK.
- You will be asked to reboot the device.
