First you must have a disk to backup your important data in computer, documents, drivers and other data you may have.

Windows Security

If your computer is used by more than one user…

  1. Install Antivirus software then update it.
  2. Activate Administrator, click Start menu, type cmd, right click cmd.exe and click Run as administrator, in cmd window type: “net user Administrator /active :yes” off course without quotes, pres
  3. Enter and close window.
  4. Open Control Panel, click User accounts, click Manage other account, choose Administrator, click Remove the password and close window.
  5. Click Start menu then Log off,
  6. Log in with Administrator .Remember the default user name that you created during installation, can be “John“, or you have written your name, suppose you set “John“, because we have to put limits for John.Ok go to Control panel click John click Change the account type click Standard user then click Change account type. Set a password for Administrator account. Now we have an Administrator and a limited account.

If you prefer that Windows starts completely with limited user “John”, click Start type netplwiz, uncheck “Users must enter a user name and password to use this computer” click Ok, User name: type “John” as always without quotes, password: type your password if you use a password for “John” if not leave blank and click Ok.

This is the way I prefer, not something you should do necessarily.
