Windows 10 typing slow

Hi,

Thank you for contacting Microsoft community.

I suggest you to follow the below methods and check if it helps.

Method 1: This issue may happen due to system file corruption. I suggest you to run System file checker. System File checker (SFC) scan is done to check if there are any corrupted
system files that could be causing this issue. Kindly follow the below given steps:

• 
  Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
  
• 
  In Command prompt type
  sfc/scannow and press enter.
  

• Restart the computer.

Method 2: If no corrupted system files were found in the previous state, then I suggest you to try the following steps to employ the DISM command lines:

• 
  Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
  
• 
  In command prompt, type the following commands and press Enter after each command:
  

• 
  DISM.exe /Online /Cleanup-image /Scanhealth
  
• 
  DISM.exe /Online /Cleanup-image /Cleanupimage
  
• 
  DISM.exe /Online /Cleanup-image /Restorehealth
  

• 
  Close the command prompt and restart the PC and check if it works.
  

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

How to change default app for file type

@Bree - yes, I'm quite aware of this thanks, but as you will see it's missing. I recall reading that clicking the dialogue at a certain point in blank space made it appear, and trying that once successfully, but doesn't seem to help now. Plenty of other similar reports of this option being missing.
