A quick question, if you create a local user account and try to login in under it - does it login faster? 

Sounds like a network resource access is timing out and your system is waiting for it to resolve.

@noxcho
I will have to give that a go next time the issue comes about, thank you. 

@serialband 

I am getting the same impression as well, I am hoping that enabling the connection to their home internet resolves this. 

Open Windows Explorer.

Go down to This PC/My Computer in the left hand column. Click on it.

In the right pain is/are there mapped drive letters that are showing a red X? 

Is the user disconnected from the network when this happens?

What does the user's computer say in the following Event Log location for errors/warnings:

I agree with serialband, sounds like accessing a network resource.

Does the user have any Cloud based file storage, like MS's OneDrive?  Our company uses that and it connect as a folder under our home directory.  So every time you logon it attempts to sync files.  If you access your OneDrive from another source and do a lot of updates, it could take awhile to sync.

If you could get a command window open, you could issue “netstat -n” to see if there are any TCP connections in the SYN_SENT status and then try and chase down what the target host is.  But from the sounds of it, by the time you can issue the command, the problem is over.

Can you get task manager up while it seems to be hung (CNTL+SHIFT+ESC).  If so you might be able to select FILE → RUN → CMD and try netstat or even look at task manager to see if there is a task that is using a lot of CPU.

UPDATE 

User has been able to sign in without issues so far. 

Recent Changes: Enable Connect to home wireless automatically at startup & uninstalled MS365 Copilot

@Phillip Elder 

Event errors and warnings are in the question submitted. 

Yes, user is not connected to the VPN yet and the mapped drives show disconnected because user is not connected to the VPN when the issue occurs. 

@giltjr 

We do not use any kind of cloud storage; we have OneDrive disabled as per GPO as well as OneDrive is uninstalled from their machines. 

Unfortunately, by the time I am able to run Task Manager the issue has subsided and the same with command prompt. If the issue occurs again, I can run netstat to see if there are any findings since I have not tried it yet. 

Thanks! 

Ok, it means that sign in with a local user works without a problem. Definitely network issue. 

Connection to wireless can take sometimes a while. I would test it by disabling this recent change. Then you have your root of cause. 

UPDATE

A Few users have encountered the issue and told us after their notebooks have recovered. All of which were not connected to the internet automatically and all have the MS365 CoPilot installed with today's date of installation on it. 

Can you check on the affected machines if other MS updates were installed? Do these machines constantly have this problem now?

UPDATE 

User is still having issues at home.

• Confirmed Notebook is connecting to Home Wireless automatically 

Replicated issue in Office on a different laptop having it set to not connect to any Wireless Access points Automatically. Issue occurs on the local admin account 

@noxcho

No MS Updates have been applied since the beginning of the month and this issue started before February Patches were rolled out. 

Task Manager shows minimal resources being used when I was finally to get it to open. 

Only Anti-Virus are listed in Startup Applications. 

Two tries would be nice to do:

1. Disable all network adapters on the machine where you can reproduce it with local system account. Check if the logon goes faster. 
2. Can you deactivate antivirus from startup or uninstall it and see if the login works faster? 

the first error refers to a  printspooler problem - here cleaning the registry was needed :

Solved: Windows Event 513 PrintService - HP Support Community - 6162167

Update

@noxcho

Disabling the Network Adapters did not change anything 

On the Testing device Removing the AV agent seems to do the trick, Able to install the agent again and the issue is no longer occurring.

Just finished uninstalling and reinstalling the AV agent on the user with this issue and hopefully it all works out. 

Thank you everyone for the comments! 

Update

Able to Replicate issue on laptop again with the AV agent installed. 

Unsure why this would affect some user machines and not others.

Seems to be something with the AV and the WiFi even after the reinstall of the agent there was no change. 

Could be AV Agent starts longer or performs scan at startup. Maybe you change the AV or request the AV-provider for known issues report.
