Head-to-Head with Windows Virtual Desktop and Its Black Screen Logon Issue

by Dec 7, 2020

When logging into a Windows Virtual Desktop (WVD) environment, you would expect a relative “quickness” to get to your desktop. However, for the past few months now, a smattering of clients have experienced a rather frustrating issue, where it can take anywhere from 30 seconds to five minutes to log in, sometimes not letting users log in at all. 

So, if you are too familiar with this 





then carry on reading to delve a little deeper into how you can solve the problem or at least decrease logon times. 


Option 1: disable the app readiness service 

The pro? This massively helps users if they just cannot log in to the environment, as well as helps reduce logon times.  

The con? This has been known to cause a few issues with Microsoftbased apps such as Outlook and OneDrive, such as not syncing and asking to reactivate. 

That said, if you are using Windows Virtual Desktop to access internal websites or resources, then disabling this pesky service is a sure-fire way to alleviate your logon woes. 


Option 2:  review your applications 

Do you have an application that has a connection to onpremise or even an on-premises exchange server? This could have some impact on logon times, not massively, but you will see some reduction. In our investigation, this can be hit and miss. 

More often than not, logon issues are caused by applications that run at logon. They may poll onpremises systems and check for any updates. 


Option 3: upgrade your Windows 10 

Another option, dependent on Windows 10 version (I am assuming you are all running Windows 10 at this point) would be to move to Windows 10 1909. Microsoft has fixed the black screen logon issue in this and previous versions with a patch. However newer versions, such as Windows 10 2004, still experience black screen logon issues. This can be problematic if you have your heart set on using MSIX App Attach, as this feature is native in 2004 and above, however, still in preview 

All in all, there are a few ways to resolve this issue. Some are more effective than others, but nonetheless, they are straightforward fixes for a rather obscure issue. 

One final point, make sure you are running the latest version of FSLogixthe latest Remote Desktop App and that your session hosts are all up to date with the latest patches and security updates.
