This is actually a old Issue that resurface for a user. So i figured it was good to post for others to be aware.

You will generally receive this error message when your copy of Windows is no longer Genuine. It means you have installed windows self proclaimed important update KB940510 via windows update. Some users have reported that this update has disabled their system if a activation exploit has been found on their system.
A activation exploit is a attempt to bypass Windows Activation process to avoid purchasing a legit copy of windows..

Per M$ they say “Note Installing this update does not affect the functionality of your operating system.” which is true if your system does not contain any activation bypass cracks.

Please note that you can opt-out of updating your system by disabling windows update. If you installed this update and wish to remove it, you can uninstall this via the control panel. You can also pruchase a legit license from the Microsoft Store

Reference

Microsoft reason for the error:
This problem typically occurs because drivers call either the IoQueueWorkItem function or the ExQueueWorkItem function two times on the same work item before the work item has been executed.

Device drivers that statically allocate either the IO_WORKITEM structure or the WORK_QUEUE_ITEM structure are particularly prone to this problem. Device drivers that perform such a static allocation must guarantee that they do not try to use the statically allocated item while it is already queued.

================================
WHAT.. that was very technical …

===============
The cause is due to a corrupt hardware driver. you will need to locate the hardware that is having the problem and disabled it. Then install the latest driver for the harddrive before enabling it.

We ran install this issue when playing with out wireless card.

M$ Knowledgbase on it

Remove the Upperfilters and Lowerfilters values completely from the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
NOTE: If you are getting a code 39 message, it may be that additional third-party filter drivers were added to UpperFilters and LowerFilters values in addition to Adaptec filter drivers. In that case, you may try to remove the non-Adaptec filter drivers first, leaving the Easy Creator filters in place to see if the Code 39 goes away. If you still receive an error code 39, 32, or 31 message, remove the Upperfilters and Lowerfilters values completely in the preceding key.

Restart your computer.

M*KB

The 401.3 error message was being displayed due to the Anonymous Authentication app pool settings. I changed the identity to the app pool instead of using the iusr account. This can be found under IIS > Authentication > Anonymous > click edit on the right. You will then need to select “application pool identity”

Fix :

you will need to change the authenication method to basic instead of Integrated authentication. This mostly effects older browsers.

There is a slight draw back to this .With basic , the login details will be sent in plan text..

M$ words
Common reasons
No authentication protocol (including anonymous) is selected in IIS. At least one authentication type must be selected. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
253667 Error message: HTTP 401.2 – Unauthorized: Logon failed due to server configuration with no authentication
Only Integrated authentication is enabled, and an older, non-Internet Explorer client browser tries to access the site. This happens because the client browser cannot perform Integrated authentication. To resolve this problem, use one of the following methods:
Configure IIS to accept Basic authentication. This should only occur over SSL for security purposes.
Use a client browser that can perform Integrated authentication. Internet Explorer and new versions of Netscape Navigator and Mozilla Firefox can perform Integrated authentication.
Integrated authentication is through a proxy. This happens because the proxy doesn’t maintain the NTLM-authenticated connection and thus sends an anonymous request from the client to the server. Options to resolve this problem are as follows:
Configure IIS to accept Basic authentication. This should only occur over SSL for security purposes.
Don’t use a proxy.
