Windows 10: Windows 10 takes a LONG time to login

A couple weeks ago, my Windows 10 computer started taking a LONG time to login. The times have been going up and down, with a max of about 15.5 minutes, which happened today. Here's what I've tried to solve this issue:

1. Do a clean boot (no startup programs or services other than Microsoft services).
2. Defrag/optimize hard drive (not SSD).
3. Run CCleaner and Malwarebytes.
4. Check the Event Viewer.

Here I found multiple warnings and errors:

1. Event 6005, The winlogon notification subscriber <Profiles> is taking long time to handle the notification event (Logon).
2. Event 7022, The Connected Devices Platform Service service hung on starting. (and a few like it, only with different services)
3. Event 6006, The winlogon notification subscriber <Profiles> took 936 second(s) to handle the notification event (Logon).
4. Event 6004, The winlogon notification subscriber <GPClient> failed a critical notification event.
5. Event 6001, The winlogon notification subscriber <Sens> failed a notification event.

After some googling, I continued with the following steps:

5. Disable "Always wait for the network at computer startup and logon" and "Run logon scripts synchronously" in the Group Policy Editor.
6. Do an in-place upgrade/repair.

There are probably some other steps I've missed, but I think that covers most of it. I'm fed up with this problem, but I really don't want to have to reinstall Windows. If anyone has any solutions or ideas, I'm open to anything at this point.

Thanks in advance!

Login box takes a long time to appear - Win 10

Someone in another thread mentioned that they narrowed it down to a service called 'DeviceAssociationService.' Though where they said enabling it fixed the problem, mine was already enabled. I disabled it and tried rebooting and it worked fine.

Who knows if it will work in the future, but for now it might have worked.

To get to it: hit start and look for services. Then in the services dialogue, just look for DeviceAssociationService, hit properties, and set it to 'disabled.'

HOWEVER: My mouse is still completely broken in that regard which I mentioned in the original post. Any help is appreciated

 

Login box takes a long time to appear - Win 10

When turning on my computer- every time since as long as I can remember (though I don't think this happened when I first got it) - the text box that I enter my computer password into to login - takes an enormous amount of time to appear.

Like- it will turn on just fine, the Login screen appears, and everything except for the text box itself appears.

It doesn't just take a long time either. It just plain doesn't show up unless I spam keyboard buttons. Eventually it just kind of seems to decide to respond and the text box appears and works fine. It's really strange.

Also, this may or may not be related, but as of late (possibly started around the same time), my mouse acts very strange on startup. Until a minute or two after I'm already logged in, it just doesn't work right. Usually it just moves incredibly
slow and clicking only sometimes works. The last few times I turned on my computer, it instead decided to only move up or down (not left or right) until it was fully logged in and booted. It's as if the mouse drivers aren't loading unless I've fully logged
on or something.

These two issues might not be related, but a solution to either one would be fantastic

 

Was "a couple weeks ago" just after installation of the AU? If so, I'd suggest a clean reinstall.

 

No it was awhile after that. I got the AU first day. The only major thing I remember doing since installing the AU is following Tech City's video on optimizing W10 AU for gaming and power users. I made some of the changes he suggested, but not all of them.
