Changing the ISO file content

To do this, I used the apps Magic ISO Maker and WinImage.

Editing the VirtualXP Registry

Within the VirtualXP.iso image file you will find the following files that belongs to the System Registry.

REGISTRY KEY	FILE
HKEY_CURRENT_USER	\I386\SYSTEM32\CONFIG\DEFAULT
HKEY_LOCAL_MACHINE	\I386\SYSTEM32\CONFIG\SOFTWARE

Copy those files to your hard drive (your hard drive must have a standard Windows installation) and run from that standard Windows installation the following lines:

reg load HKCU\OFFLINE C:\DEFAULT
reg load HKLM\OFFLINE C:\SOFTWARE

Those lines will mount the VirtualXP Registry in:

• HKEY_CURRENT_USER\OFFLINE
• HKEY_LOCAL_MACHINE\OFFLINE

Now open the Registry editor and at the mentioned location you will find all the settings that VirtualXP is using. Modify all the things that you may need in there and after that run the following lines:

reg unload HKCU\OFFLINE
reg unload HKLM\OFFLINE

Those lines will:

• Remove the HKEY_CURRENT_USER\OFFLINE Registry.
• Remove the HKEY_LOCAL_MACHINE\OFFLINE Registry.
• Unmount the DEFAULT file and save changes in it.
• Unmount the SOFTWARE file and save changes in it.

After this, you must copy the modified DEFAULT and SOFTWARE files back to the VirtualXP.iso image file.

The MODELRAM.EXE file

Within the VirtualXP.iso image you will find the \MODELRAM.EXE file that it is self extracting exe file created with the 7-Zip command line that automatically extracts the Documents and Settings folder in the RAMDisk when VirtualXP is booting. The command to create this file is the following:

7z a MODELRAM.EXE -mx9 -sfx "Documents and Settings"
