Hi Guys. Just joined....I have had this problem for months. Just done a complete recovery to try and correct...just Windows Updates and nothing else, and still getting lockup. I have not install Silverlight 5 as it did not work last time...Just wish these large companies would talk to one another.....Hopefully someone, somewhere has the answer. It seems that I research this problem 3 or 4 times a week. One site I went to today suggested that MSE might have an influence on netflix issues. I am seriously considering installing Windows 7 only (no HP or other manufacturers software, except TV tuners and Video card requirements). All "we" want here is a stable platform for watching TV...
