Currently, my Windows 10 install (Pro edition, build 10586.29) is experiencing a problem with extremely slow logins (up to three minutes on the "black screen of death" -- cursor is visible, but absolutely nothing actually happens) after entering my login password. Additionally, the Windows Shell can take upwards of five minutes to load (items to display on my taskbar, shortcut icons to load, etc).
I've attempted to attach a debugger (through
procmon) to my boot process, but I have yet been unable to find anything out of the ordinary, with the exception of about a three minute gap between two registry lookups:
All of this happens before
UserInit start (I think).
During this gap, many processes (Specifically NVIDIA and ELAN) launch, but none seem to contribute to a hang.
I have no idea about how to debug this, what's causing it, and (most importantly), how to fix it. Can someone please help me out?
Winlogon's process tree:
Edit: I've noticed that this only happens when I first boot my computer. Any subsequent logons/logoffs work perfectly normally.
Edit 2: Upon doing a bit of log debugging, I noticed something in my boot logs:
This application took longer than usual to start up, resulting in a performance degradation in the system startup process: File Name : MsMpEng.exe Friendly Name : Antimalware Service Executable Version : 4.9.10586.0 (th2_release.151029-1700) Total Time : 48205ms Degradation Time : 45705ms Incident Time (UTC): 2015-12-13T05:50:13.777810900Z
This suggests something is wrong with Windows Defender (again). Now what?
Edit 3: Also, I'm using Razer Synapse because of my keyboard and mouse, and quite a few different people confirm that it actually does slow boot. Can that be remedied somehow (preferably without uninstalling Synapse)?
