How to activate Windows without additional programs for free

For real pirates: most have unofficial Windows. When activated, you can catch a virus. To prevent this from happening, do not download programs to install Windows. You have enough built-in features.
How to activate Windows:
- Open “Start”, write in the search “Powershell” and run it as administrator.
- Enter “slmgr / skms kms.loli.best” and close the window that appears.
- Do the same with “slmgr /ato” and “slmgr /xpr”. Just wait a little and you’re done!
To check if everything is installed correctly, press the key combination “Win + I” and open the section with updates. Enjoy!
