I know this has been asked about hundreds of times, so I did some of my own sleuthing.
I found some extra relevant files to edit and integrate into the image.
My edits to medctroc.inf were probably the most dangerous. I was copying updated ehome files into a new cab and there were some different lines concerning the languages. Like this:
fr\ehepg.resources.dll,ehresfr.dll de\ehepg.resources.dll,ehresde.dll ja\ehepg.resources.dll,ehresja.dll ko\ehepg.resources.dll,ehresko.dll zh-chs\ehepg.resources.dll,ehreschs.dll it\ehepg.resources.dll,ehresit.dll nl\ehepg.resources.dll,ehresnl.dll ;Edit by Patrick - May 26, 2015 fr\ehepgdat.resources.dll,ehresfr.dll de\ehepgdat.resources.dll,ehresde.dll ja\ehepgdat.resources.dll,ehresja.dll ko\ehepgdat.resources.dll,ehresko.dll zh-chs\ehepgdat.resources.dll,ehreschs.dll it\ehepgdat.resources.dll,ehresit.dll nl\ehepgdat.resources.dll,ehresnl.dll ;End Edit
So I put both in, but I don't know if I should only include one or the other. The additions are from SP3. I would like to know if anybody knows about this.
Also, I would have liked to upload all my edits in a zip file for your scrutiny, but my computer gave me the middle finger just now and my backups are gone, and nlite "optimized" the ones I copied into the install. I am really POed right now, way too POed to just recreate them, and will probably wait until tomorrow to sift through the mess I've made and try to recreate what should be right @#&!ing there.
Anyway, in theory, I have not tested this yet, but MCE should be fully functional without any extra work. No shoving an M$ distributed MP10 in bare to patch the fact that SP3 purposely downgrades it to 9; I copied the necessary lines over into the appropriate files so User Mode Driver Framework is installed too. I had the updated files from hotfix rollup 2 and oct 2006 patched in. I've even edited the kernels to show a Media Center boot screen just for fun, and if it doesn't say MCE in the system information I have a workaround ready for that too.
