Yes, good points, and I did know that the v10d was different from the weekly/daily packages. But yes, I did install UURollup-v10d over the weekly version, which I actually didn't think was going to work and I ended up with the kernel32.dll blue screen. So I uninstalled and went back to my weekly version, no problems. However, since I wanted to try out the stable v10d, I decided to uninstall my weekly version to go back to a somewhat native environment, but that also resulted in a blue screen which I outlined earlier, saying that it couldn't find LdrLoadLock or something like that in ntdll.dll. Why that happened, I had no idea. So then I was stuck with a system that wouldn't load. But since I had nothing to lose, I went into the recovery console and tried the uninstall of v10d since earlier I had installed it over the weekly version which meant before it installed originally, it saved copies of my weekly version's system files, and initiating uninstall of it once again restored the good system files and I was able to use the system again as it was before anything happened. So basically, rather than pointing out my stupidity of seeing what happens when you experiment with certain things, I posted that just in case someone else might try doing something like what I had done or similar and how they could get their systems back without having to wipe the drive and start all over again.
