<TL;DR> Does anyone run an activated Windows 8 Pro MC x64 9200 and need testsigning to be on? If so, do you have a working solution for removing the watermark above the clock? </TL;DR> The watermark says: ---- Test Mode Windows 8 Pro with Media Center Build 9200 ---- A quick Q&A: Q: Just activate windows properly and all watermarks will go away. A: This is not an activation watermark. My W8 is activated anyway. This watermark is simply a result of having testsigning on. -- Q: Hey noob, why not just read one of the 5,863 threads already available on this subject instead of making another one? A: In the threads that are actually talking about activated W8 9200, there seems to be a few common solutions: 1) Turn testsigning off (this won't work for me), 2) Use 'My WCP Watermark Editor' (For one, I have trust issues with random .exes. Another thing here is that I tried it inside a virtual machine only to have it freeze the first time [requiring an sfc /scannow] and then only half work the second time, leaving only the middle line.), 3) Use this W7 solution from 2009 (can't post links, otherwise I would link to it. The bottom line is that it doesn't work), 4) Try a registry fix (again, would link if I could...but tried this fix already and it failed). -- Q: Why not just turn testsigning off? Code: bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS bcdedit -set TESTSIGNING OFF A: This really won't work. I need to have it enabled so I can run certain drivers. ---- I figure the offending watermark is probably somewhere inside shell32.dll.mui and/or unimdmat.dll.mui and/or user32.dll.mui and/or another file, but I haven't a clue about how to go about editing them properly. I really would prefer a less hacky solution (or more easily reversable...I guess it's not that hard to just do a bunch of .baks), but not sure there is one.
