winisoutils - Windows ISO Disc Image Utilities

ei.cfg Removal Utility

The ei.cfg Removal Utility is a simple tool that will remove the ei.cfg file from any Windows ISO disc image, thereby converting the image into a "universal disc" that will prompt the user to select an edition during setup. This tool works by toggling the deletion bit in the UDF file table, eliminating the need for unpacking and rebuilding the ISO, which means that this is extremely fast (the process of patching the ISO to remove ei.cfg takes only a fraction of a second), and the process is easily reversible (running the utility on a disc image patched by this utility will restore the disc image to its original state).

cversion.ini Removal Utility

The cversion.ini Removal Utility is a tool that will remove the cversion.ini file from Windows ISO disc images, thus enabling the option for in-place upgrades that preserve user settings and programs. This is very useful for upgrading from release preview versions of Windows to the final version (e.g., Windows 8.1 Preview to Windows 8.1 RTM) while preserving your data, settings, and programs. This tools works in the same fast, efficient manner as the ei.cfg Removal Utility, so there is no need to unpack and rebuild ISOs, and the process can be trivially reversed.


[obsolete and no longer maintained] The Windows 7 ISO Image Edition Switcher is a set of small binary patches (and a tool to apply these patches) that will convert an official Windows 7 ISO disc image into an official Windows 7 ISO disc image of another edition. The resulting ISO images are bit-for-bit identical with those posted on MSDN or TechNet, and their SHA-1 hashes should match the official hashes posted by Microsoft.
