Windows 10: what should i do if i delete the UnknownS-1-15 file

I deleted the UnknownS-1-15 file and i watched a video on YouTube about it and the guy from the video said you should not do that but i did and i dont know what to do

:)

 

unknown access to file

I found out the following:

• No other folder has the unknown access in the security tab.
• When I add a new link to the Favorites folder I get the same 4 Unknown lines. They all start with the same security ID number S-1-15. None have full control permissions.
• Doing a search on Google I found out: "S-1-15 - Used for "APPLICATION PACKAGE AUTHORITY" SIDs, used to manage permissions of modern-style apps in starting with Windows 8."

I am no longer concerned about this.

Step 1 - I upgraded to Win 10 and lost all my files on Desktop.

Step 2 - Found the files in Network - USers- Desktop

copied all files again to desktop.

Step 3- Restarted my machine again and lost desktop files again.

Step 4 - As suggested did the following as listed below but dont find my files.

• Press “Windows + E”, open This PC/Computer
• Open Local Disc C, open Windows.old
• Click on Users, select your User name

Cant find my files. Why is Win 10 deleted files again and again from Desktop ?.

 

Unknown User Account created after upgrading to windows 10. It comes back if I delete it.

Original Title: Unknown User Account

Hello,

Since I upgraded to Windows 10 I am seeing an account that I did NOT create. So I deleted it by going into Control Panel > All Control Panel Items > User Accounts > Manage Accounts then I click on the unknown user account and delete it. That said.... It
comes back. I have also followed the below suggestions from other posts and still does not seem to work.

Let’s try simple steps and check if the user account is detecting and try removing it.

• 
  Press Windows key + R, type netplwiz and press Enter.
  
• 
  Check if the user account is appearing on the list.
  
  
• Click on user account and click on Remove. (If user account appear on the list).

Please advise.

Thank you
