If you didn’t know – Microsoft stopped supporting Windows 7. So, Windows 7 is finished and not safe.
If you still use Windows 7, Microsoft is currently providing free upgrade to Windows 10. Visit this link at Microsoft and follow the instruction. If you need further information, search articles online.
I just upgraded my computer last night, the whole process went very smooth. I was pleasantly surprised. I did make complete hard drive backup before AND after the upgrade as a routine procedure.
Anyway, free upgrade is going on right now. I don’t know when they will stop providing free upgrade. I have one more computer to upgrade.
