Hi, check the license first. KMSpico is the activator being discussed. The kmspico page explains how an unofficial tool imitates KMS, but that is not a valid family licensing plan. Make a small inventory with the device name, Windows edition, activation status, Microsoft account and proof of purchase. During reinstall, choose the same edition and let an existing digital license reactivate. Use the Activation troubleshooter after hardware changes and contact Microsoft when ownership is unclear. Do not share product keys in screenshots or store them in public cloud notes. Keep security software enabled, and buy missing licenses only from Microsoft or an authorized seller.
