Windows 10: Problems with Screen Redraws in Powershell/CMD/Explorer in 19042.421

My laptop Thinkpad X13, Ryzen 4750U updated to 19042.421 earlier this evening, and suddenly PowerShell, the Command Prompt, and a lot of Explorer applications aren't really updating unless there's a screen redraw.


If I open PowerShell and type a command, it won't appear unless I try to alt-tab to something else or "view all desktops" or the like. Commands after this complete sub-satisfactorily. If I type "ls" I'll occasionally get results instantly, but won't get the next command prompt without alt-tab, changing desktops, etc.


In Explorer apps too if I try to look at, say, Powershell Properties, the window outline will get drawn, but not without significant cursor movement or above changes will the window actually appear.


This was fine in my earlier release! I've been using Powershell heavily the past few days and this change is not great.

CMD and PowerShell

Hi Andre,

I did all items you listed.

After reboot, running CMD and powershell (admin) had the same result ("no app associated"). So I turned the feature off in taskbar settings.

Windows Explorer crashes and thumbnails problem

Hi, I hope you can help me.
Windows Explorer is no longer showing thumbnails on files played by Windows Media Player. I've run cmd and regsvr32 shmedia.dll and regsvr32 shimgvw.dll. That seemed to solve the problem...but it created a different one. Now when I try to open a folder on an external hard drive it crashes. I read in an old 2008 post it was an avi file causing the problem and suggested the run cmd regsvr32 /u shmedia.dll. That solved the opening problem but recreated the thumbnail problem. Any help to achieve both functions would be greatly appreciated. Thank you.

 

File explorer

Hi Mick,

I am sorry to know that the File Explorer is not working on the Taskbar.

I suggest you to right-click on it to unpin it from the task bar.

Then search for File Explorer in Search. Then right-click on it to Pin it to Taskbar.

If the issue persists, try the steps below.

• 
  Type CMD in Search. Right click on it to run as an administrator.
  
• 
  Type the following 4 commands at the Command prompt:
  

dism /online /cleanup-image /restorehealth

sfc /scannow

powershell

Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

• 
  Close the CMD window.
  
• 
  Check to see if the issue is resolved. If not, restart the PC.
  

Hope this helps in resolving the issue. If the issue persists, do get back to us. We will be happy to assist you.
