1. Type "Cleanup" in the search field of the Startmenu.
2. Open it with an administrative account
3. Choose "Previously Windows Installation(s)"
4. Press OK

Gain admin access on cmd

The so called "elevated" command prompt can be gained in a few ways:

1. open cmd as admin

net user administrator /active:yes

Reboot

Now the admin is in the login window

2. Enter cmd.exe in startmenu and open it with rightclick "run as admin"

3. open cmd and add yourself to the admin group (DANGEROUS!!!)

net localgroup administratoren %username% /add

Complete reset of network stack

https://stackoverflow.com/a/64057835/1319799

Also works up to Windows 11 (which shows how old this crap is):

  wsl --shutdown
  netsh winsock reset
  netsh int ip reset all
  netsh winhttp reset proxy
  ipconfig /flushdns
  netsh winsock reset
  shutdown /r 

Reset winsock only

Sometimes the windows network stack (winsock) ist broken. To solve the problem: open a cmd window (you need an "elevated" command prompt: right click as admin!).

netsh winsock reset
#netsh int ip reset catalog
#netsh int ip reset reset.log

netsh int ipv4 reset

Reboot

Same with Fix-Link
