Hi all, I've got a Win8 SurfaceRT tablet, and as you are probably aware, these things are quite locked down and will only allow signed executables to be run. Basically, I wish to copy some windows binaries from a live system (I have located them from within the C:\Windows\WinSxS folder) and copy them into the Windows Recovery Environment for RT which can be executed from a bootable USB drive. As expected, signed executables are also enforced even within the Recovery Environment. The binaries that I have copyied to the Recovery Environment will not execute as they need their corresponding catalog (.cat) file and manifest file (I've found the mnaifest files). The cat files are stored within a 'Catalogs' folder under 'WinSxS' and are named like this: 01f3c856dc2d7f774c54faf7eeebd203293c57ad8f0a291bc4d0fe1d84167437.cat So here is the question, how do I resolve these catalog files to the manifest and windows binary files? Thanks in advance.
