You can switch users in Windows 11 without restarting the PC. Open the account menu, choose another account, and sign in with that person’s credentials. The account you leave stays signed in, so you can return to it later.
- Press the Windows key, select your account name or picture in the menu that opens, choose the other account, and sign in.
- To see which accounts exist on the PC, go to Settings → Accounts → Other users.
- You can also press Windows + L or Ctrl + Alt + Del and pick another account from there.
