Remote Desktop Issue: “An authentication error occurred” “This could be due to CredSSP encryption oracle remediation”

You may get this error when trying to connect to a Terminal Server from Windows 10 or Windows 7.


The workaround is to add the following Registry key on the affected client PC.

This is NOT a fix. Doing this will bypass the fix for the security vulnerability. But it will get your users going while Microsoft readies a fix.

How to remove Built-In Apps in Windows 10

Here is a tutorial on using PowerShell to remove the WIndows 10 Built-In apps. This is useful for providing a standardized PC environment to users in a work environment.

Basically, several PowerShell commands are used. The following commands show and remove apps from the user account.

  1. Show a listing of all the installed apps on the computer – Get-AppxPackage | Select Name, PackageFullName
  2. Remove the app – Get-AppxPackage [PackageFullName] | Remove-AppxPackage (you can put this into a script for multiple apps, or use wildcards)

Variations include uninstalling the app from all user accounts by adding -allusers –  Get-AppxPackage -allusers [PackageFullName] | Remove-AppxPackage

If you need to re-install a particular app, you can use the following command – Add-AppxPackage -register “C:\Program Files\WindowsApps\[PackageFullName]\appxmanifest.xml” -DisableDevelopmentMode

Partitions may be missing after installing the Windows 10 Anniversary Update

The main thing to glean from this issue is “not try to recover or otherwise write data to the affected partition, nor should you format the partition”

From Microsoft –

Microsoft has received a small number of reports of partitions not appearing in File Explorer after installing the Anniversary Update. When viewing the partition in Disk Management, it appears as RAW, unallocated space.
Microsoft is aware of this issue and is working on a solution to be released through Windows Update. Any data you have stored on the affected partition is still there. We recommend that you not try to recover or otherwise write data to the affected partition, nor should you format the partition. We will update this thread when a patch is released. If you would like to be notified when this thread is updated, click the Subscribe button at the end of this post.
For up to days 10 days after installing the Anniversary Update, Windows includes the ability to “go back” or return to the previous build if you are experiencing this issue and do not want to wait for the patch to be released.

To uninstall the Anniversary Update:

  1. Open the Settings app.
  2. Select Update & security and then the Recovery tab.
  3. Under “Go back to an earlier build”, click the Get started button and follow the instructions.

(Note: If more than 10 days have elapsed since installing the Anniversary Update or the “Go back” option is otherwise not available; we ask for your patience until a patch can be released. Please check back on this thread for an update.)
