Announcing Windows 10 Insider Preview Build 19592

Other than the weird task bar issue that you noticed and posted about already, it looks like the problem with the mouse cursor in 32 bit WPF apps hasn't been resolved yet. Here's hoping it gets fixed at some point soon.

I am not sure if this has anything to do with that VPN "issue" I posted about on the last update, but I noticed in the sign in box for the Windows VPN client, it no longer shows the domain name below the password box like it does in 1909 and previous builds of the fast ring:

Even stranger, it allows me to log into my Meraki VPN without having to pass in the actual domain name. 

As I stated previously, I'm able to work around this by just using the IP addresses. I also tried the fix that I used previously (changing the interface metric in the IpV4 settings for my ethernet adapter and the actual VPN connection's IPv4 settings) and that doesn't seem to work anymore.
