Hello, I've been having issues with Windows 10 LTSC for months now and I have tried everything I can to fix them. Unfortunately I ended up needing to come here and soliciting the time and knowledge from others since I just don't know where else to go. In hopes of taking the least amount of your time, I'll neatly spoiler what's the issue and below it, the solutions I attempted. The problem: Spoiler What made troubleshooting the hardest is that there is no clear issue here. Installed applications randomly stop working after a restart and require reinstallation to start working again. Some applications randomly crash and the only trace they leave in the Windows Event Log is a very vague "Application Error" line which doesn't give me any specifics. Example: I installed Thunderbird for my e-mail and after a few days it just didn't want to open anymore. I clocked the icon and it would instantly crash leaving a single "Application Error" line in the Windows Event Log. Same thing happened with a few other applications, but in similar ways. Telegram, MPC-HC and Waterfox are all programs which have suffered similar fate. Some applications also install correctly, work correctly and then start to randomly crash. For example, I use VSTHost for my voice processing. Sometimes it works perfectly for hours on end, sometimes it works for 30 minutes and it just crashes without any error message or trace besides the "Application Error" thing in the log. That "Application Error" line seems to be the one thing connecting all of my issues listed here and I'd love to know if there's a better way to debug it somehow? My attempted fixes: Spoiler I was running my PC with quite heavy overclock on my CPU, GPU and RAM at the time. Of course, I completely disabled all OC and reinstalled a fresh version of 10 LTSC downloaded from a torrent file posted here. Unfortunately it seems like the OC wasn't the issue since the problem persisted even after reinstallation. I thought it could possibly be a straight up hardware failure, so I ran Prime95 for almost an hour without fail. I also let MemTest86 run all of it's tests four times in a row, and it also passed them all without errors. The only thing I can imagine failing here is the storage, but the S.M.A.R.T. tests show up clean. I tried going through the Windows Event Log but it didn't give me any conclusive information on the nature of the issues as noted above. My PC Specs: Spoiler CPU: AMD Ryzen 5 2600 @ 4.0GHz (OC) GPU: Asus GTX 1050Ti RAM: 16GB Corsair Vengeance LPX (DDR4 @ 3400MHz OC) MBO: Asus Prime B450M-A Storage: 250GB Samsung 970 Evo Plus + 2x 1TB HDD PSU: FSP Fortron Hexa+ 400W TL;DR of my questions Basically, if you can't help me with my issue specifically, I'd politely ask you to at least point me in the right direction. What's the best way to get more precise info from Application Errors and crashes? NirSoft's "AppCrashView" doesn't show anything. Also, what's the best way to test my storage components? I'm assuming there is some form of data corruption happening since things just fail at random? If you think I'm completely off, could something else be the issue? Maybe the ISO I downloaded was somehow corrupted and I should build my own from the SVF? This did happen with three different installations of Windows 10 LTSC by the way. Any input is appreciated. I've been trying to solve this issue for months now and I don't know where else to turn nor what to do. Thanks upfront for your time! EDIT: The cause has been a virus infection! Applications were crashing when the virus tried to inject itself into them! If you're having the same issue, try scanning your PC with an AV!
