Microsoft explains Windows 10 Black Screen login issue, working on fix

September 19, 2017

Earlier this week, we reported about an issue in the latest Windows 10 update that results in a 5-10 minute lag during login. The issue only affects some HP devices at the moment, but there isn’t any official fix available for the issue as of yet.

Microsoft today acknowledge the issue, offering some details and a workaround for advanced users. The company is actually blaming the issue on HP, stating that some OEM factory images create “incorrect registry keys” which cause conflict with the app readiness service in Windows:

Some OEM factory images create incorrect registry keys during image creation. These registry keys conflict with the app readiness service. After 5-10 minutes of black screen the user will regain use of their device. This issue is triggered on every reboot.

According to The Register, Microsoft is working on fixing the issue already. In fact, the workaround for the issue is already available below, but do keep in mind that if you aren’t too familiar with the Windows registry, we wouldn’t recommend applying the fix:

  1. Click the search box on the taskbar and type REGEDIT.  Click OK.
  2. In the Registry Editor, locate the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\Applications
  3. In the Registry Editor, select the sub-registry key with a registry key name that begins with one of the following:
    1. Microsoft.NET.Native.Framework.
    2. Microsoft.NET.Native.Runtime.
    3. Microsoft.VCLibs.
  4. From the Registry menu, select Edit and then Delete.
  5. Repeat Step 3 and Step 4 as necessary.

Microsoft isn’t saying when the company will release an official fix for the issue, but we’ll make sure to let you know once the fix is available.
