My HP computer will not download Windows Automatic Updates. Somehow they got turned off, and the computer will not let me turn them back on. I have even gone to the Automatic Updates website and tried to download/install from there, but nothing works. I have scanned the computer for both viruses and spyware; it tested negative. I have tried to install the updates with the firewall down, which made no difference. I am currently on a large network and I believe the fact that Windows has not updated is causing my computer to randomly freeze completely (which it had no prior history of doing.). I would appreciate an accurate and informed answer. Thank you.
