Activating Microsoft Windows 10 & Office 2019

Published on 7/12/2025

We can use Windows 10 for free without activation / product key. It will have most functionality, except for changing wallpaper etc. MS Office can only be used in trial period, after which files can’t be edited.

Downloading setup

Windows 10 setup can be easily found it microsoft website. But not Office 2019. They are promoting Office 365. But the file is available in microsoft website somewhere whose link can be found in some other websites.

Don’t download any setup from other sites, as it might contain viruses. And people tend to stop antivirus to run activators.

Activating

To activate, there is an option called Key Management Servers (KMS). In addition to KMS servers hosted by Microsoft, other servers can be setuped by enterprises. This is being used to illegaly activating it. Most probably Microsoft is ok with this. They don’t care if some random person pirates it.

No software need to be installed for this. No activator. Just some commands which are not malicious. Care should be put to not execute commands from websites, which can download and execute any script from internet.

This seemed difficult at first. Once done, it feels easy to me. We should thank whoever put unofficial KMS servers out there, for us to illegaly activate windows/office. And I guess KMS servers can’t get access to our systems.
