Lock Screen keeps changing

Hi,

Thank you for writing to Microsoft Community Forums.

Windows Spotlight picks the photos from Bing and displays them in the lock screen. I understand that you have set a picture and it is getting changed automatically.

I suggest you to follow the steps to select the Picture that you want to be displayed on the lock screen. Please follow the steps mentioned below to set a Picture to lock screen:

2. Click on Personalization.
   
3. Click on Lock screen.
   
4. Click on the drop down under Background and select
   Picture.
   
5. Click on Browse and select the picture that you want to set.
   

Hope it helps.

Change Lock Screen Display Off Timeout in Windows 10


It won't send you to the lock screen when the timeout has been reached.

Console lock display off timeout is the amount of minutes Windows will wait idle with no activity while on the lock screen when a user locks the computer before timing out and automatically turning off the display.

You might see if these below may be turning off the display instead.

Hi Subhadeep,

Windows Spotlight is an option for the lock screen background that displays different background images and occasionally offers suggestions on the lock screen.
To turn off Windows Spotlight, go to Settings, clickPersonalization,
select Lock screen, under Background select a different lock screen background.

To avoid messages on your lock screen, you can consider the following:

• Make sure that the "Get fun facts, etc" on your Settings is turned off.
  
• Disable “suggestions” that appear as notifications. To do so, follow these steps go to
  Settings, then select System, then click
  Notifications & actions and turnoff “Show me the Windows welcome experience after updates and occasionally when I sign in to highlight what’s new and
  suggested”.
• Disable “tips, tricks, and suggestions”. Head to Settings then select
  System, then click Notifications & Actions and disable the “Get tips, tricks, and suggestions as you use Windows” option.

Don't hesitate to reply on this thread if further assistance is needed.
