I am actually at Embedded World in Nuremberg and I have been asked a couple of times about the possibility to not have any pagefile on a Windows Embedded Standard OS. Even if Windows Embedded Standard is based on Windows XP Pro binaries, the pagefile is not mandatory. This is something you have to consider when you are planning to use write filters: whether to disable of to change the location of pagefile.
You can disable pagefile by modifying settings of a component. Depending on the type of hardware you have, you will need to include one of these components in your image: MPS Multiprecessod PC, ACPI Uniprocessor PC, Advanced Configuration and Power Interface (ACPI) PC, Standard PC, ACPI Multiprocessor PC, Compaq System Pro Multiprocessor or 100% Compatible, MPS Uniprocessor PC,…
All these components provide a settings panel enabling activating/deactivating pagefile support and configuring it:
If you want or need to keep pagefile support in your OS and still want to use write filters, then you would certainly have to consider changing it’s location. Follow these instructions: http://msdn.microsoft.com/en-us/library/ms912851(WinEmbedded.5).aspx
