Windows 10: Task View Malfunctioning: Screen Goes Blank and Tabs Won't Clear

A few months ago, I opened 42 tabs in Task View because I was bored. Since then, Task View has not been working properly. When I tap on it, my screen goes blank, and I’m unable to view or remove the tabs from Task View. How can I fix this issue and restore Task View to normal functionality?

:)

 

Screen goes blank after changing BIOS settings/

I don't know how long this has been happening, a few weeks at least, but whenever I change a setting in my BIOS (and save & exit), my screen goes blank and my monitor goes into standby. Any suggestions to fix this?

 

Unable to clear all Task View items

Hi Matthew,



Thank you for posting in Microsoft Community.



I understand that not all the Task View history is cleared from the Timeline in your Windows 10 computer.

Ideally, when you use the option to clear Activity History, this would clear all the viewing history from the timeline. However, we can check a few settings and see if you are able to clear the Task View timeline.



I would suggest you to check
Manage activity history settings and see if you are able to clear the Timeline.
Please make sure to read the “Notes” section before making the changes.

If you want to clear the entire Activity History from your device, you can you can clear and delete both the activity history stored on your device and sent to the Microsoft cloud. Select
Start, then select
Settings>
Privacy>
Activity history. Under
Clear activity history, select
Clear.



If you still see the items in the timeline, you can try the manual steps:

• Press Windows + E key to open
  File Explorer.
• Browse to C:\Users<Your User Name>\AppData\Local\ConnectedDevicesPlatform\
• Search for the file ActivitiesCache.db.
• Right
  click on Taskbar and open Task
  Manager.
• Go to Services tab and look for the service
  CPDUserSvc_XXXXXX <XXXXX is a random number>
• Right click on the CPDUserSvc_XXXXXX
  and select Stop.
• Now go to ActivitiesCache.db and rename the file to
  ActivitiesCache.db.old. Delete the rest of the file in the folder.
  Do not delete the folder.
• Restart the computer and check if the items are still in the Task View Timeline.

Let us know how it goes.
