My HP has an Athlon X 2 64 bit . How do I block updates ? A computer dummy in Japan ....
Are you running Windows 10 Pro?
If so, click Start, Settings (the gear icon), Updates & Security, Advanced Options (under Update Settings), turn on Pause Updates.
I don’t know if you have Windows 10. You are probably stuck with them. I use 8.1 and goto control panel, system and security, system, Windows Update (lower left), Change Settings, Never check for updates.
