Windows 10: Why does my computer become delayed all of a sudden?

This started about a week ago, I'll be playing a game or something and all of a sudden everything will become delayed by about a second and my mouse will almost freeze completely. It happens every once in a while but last for about 3 to 5 seconds and really gets in the way when gaming.

5 min delay on cold start between login screen and bg screen

Ok, let the powershell command run overnight
If the command didn't solve the problem, the try these steps in order:

1. Disable superfetch service
   • Empty the following folder c:\Windows\Prefetch\
   • Restart the computer
   • Si ça ne marche pas, passer à l'étape 2;
2. Disable the AppXSvc from the registry: change the "Start" key value from 3 to 4 (see the screenshot)

 

sound delay

Hi Jakob,

We would like to know if you are pertaining to the Action Center in
Windows 10, can you tell us if there's a delay either on sounds or the notification, or both?

This issue is quite unclear and incomplete to be understood which notification you are talking about. It is too broad for us to distinguish the main reason why you are having challenges/concerns with notifications. To have a better
understanding of your concerns, we'd like to ask you some questions:

• Are you making a program or editing a script?
• What feature of Windows 10 are you experiencing sound delays? Can you specify? Is it from
  Alarm, Calendar, Action Center, etc.?

• Have you successfully performed this activity before?

• What were the recent changes made on your computer before you experienced this issue?
• What troubleshooting steps have you done so far?

We're looking forward to your response.
