After bricking my system trying to prevent Windows Update from running, I reverted to a clone I made a while back of the largely unmolested factory fresh HD which originally came with my Samsung Notebook 9 Pro. Interestingly, on this old version, Windows Update and the associated 'wuauserv' service don't appear to be able to pull themselves out of the Disabled state I put them in. So there's no invisible downloading here. On the version I messed up, I had installed a couple of security updates MS had frightened me into downloading; I strongly suspect those had something to do with overriding the user's ability to prevent MS from violating my computer. The OS version I got with my Samsung was, literally, the last version before turning into the kind you don't really own, but just sort of let MS run on your hardware and do whatever they like with, minus any sort of permission. I mean.., if some future update decides on a whim to load itself into your computer and only allow the viewing of inspirational social Marxist videos -or which shunts off all your emails and documents to the State for 'assessment', what are you going to be able to do about it? Exactly. MS crossed a line and barely anybody seems to have noticed. (Apple users were there years ago, of course, but what else would you expect from the creepy pod people?) So it looks like I'll be living in a previous version of Windows 10 while the rest of the world moves ahead (to meet and bow before their Robot Overlords). Good luck, everybody! (FWIW, before I rolled back, I think I'd figured out how to prevent updates. -I believe you can use the permissions and ownership feature to specifically tell svchost.exe to ignore commands/requests when they come from wuauserv. I was going to try that next, but like I said, the problem seems to have gone away.) If anybody wants to give it a try: 1. Find Windows/System32/svchost.exe 2. Right click on svchost.exe. 3. Select "Properties" 4. Select the "Security" tab 5. At the bottom where it says, "For special permissions or advanced settings, click Advanced." Do that. 6. Click, "Change" (after the "Owner: __________" line) 7. Wait for a while. The computer is crunching. 8. A box comes up which with the title, "Select User or Group" In the text area, type, "Administrators". Hit OK. You now have ownership of the file. You are now powerful. Be careful what you do with this power; I foolishly turned off the ability for any software to execute svchost.exe, and that locked up my computer so that the login screen would no longer load. (The front page login, along with a ton of other services, requires svchost.exe). So don't do that. If you don't have a clone of your original HD like I did, you've just turned your computer into a paperweight. But I think you can add a line explicitly telling svchost.exe to ignore requests from just wuausery, (the update service process name). If anybody gives it a try, post here and let me know if it works.
