It took me 14 hours today to debug this issue on my brand new system. The system goes as follows: AsRock Z390 Phantom Gaming iTX/ac, Core i9 9900k, 32 GB DDR4 3000 MHz XMP RAM, RTX 2080Ti, Samsung 970 Pro 512 GB [OS - Windows 10 Pro Genuine], Samsung 970 Evo 2TB and PSU is SilverStone SFX-L Titanium SX800-LTI 800W, all is under mid-ranged water cooling from Aquacomputer and EK-WB, running on Dell Alienware 35 something something 2560 x 1080p display, meaning I'm no 4k guy juicing my PC. That said, the PC is a state of art HW, shouldn't have any issues of any kind whatsoever. I'm running newest BiOS on my motherboard [P1.50] and...
After 14 long hours of debugging today, I found out that service called Windows Management Instrumentation is causing massive freezes, stutters and slowing down everything. When I move window in Windows Explorer, the cursor of the mouse "sticks" to the upper part of the windows, and I can move "another" cursor while the window is slowly moving like in slow motion.
Also, opening My Computer, or any folder shared via SMB from my server is taking ages. Start works slowly, everything is terrible.
When I disable in msconfig, or services.msc the Windows Management Instrumentation, I'm getting what I paid for. Fluent, near-light speed experience. As soon as I enable the WMi, hell breaks lose on my computer.
Is this a known issue of Windows 10 Pro, 1809, Build 17763.379? Or is it something "at my side" and HW/FW specific?
Also there's absolutely no high CPU usage, nor GPU usage, nor SSD, network, or any other usage. Everything runs up to 10-15% and hovers around 0%. It's just slow.
With kind regards
//edit 1: I tried leaving it enabled, manually running it [it starts automatically] and it shows errors to literally every single process it works with in an Event Viewer log. The only way how I can use PC normally for now is to disable it completely, where Eset isn't working well with it disabled :/
