Very confusing. I cannot even download SpinRite due to such message. I must be doing something wrong. I thought all I had to do was click on the links provided and immediately download SpinRite on Windows 10 Home version on my HP Spectre. I don't know if it is related, but I have been getting Windows Update error 0x80073701 also for about 3 months. I have not been able to resolve the error despite multiple attempts and following many suggestions from Microsoft & others online. I hoped downloading SpinRite would fix the 0x80073701 error, but, alas! I cannot download SpinRite. Any suggestions will be much appreciated. Immensely enjoy listening to Security Now. Thank you in advance.
