Activate Windows 10 through official channels or trusted third-party services.
Hello. Switching components like the motherboard, CPU, RAM, and PSU might require re-activating Windows since some users believe you should reinstall the previous version before upgrading. Others suggest reaching out to Microsoft support for assistance. Do you have to purchase Windows again, or is there a cost involved? I used Windows 10 Pro and upgraded from an 8.1 retail edition—was there any expense needed?
Windows keeps keys on the motherboard since version 8, meaning you must locate the license key using a program on your PC first, then copy it and try again. If that doesn’t work, Microsoft support can assist, otherwise you might find help on Reddit or G2A.
