Just in the last few weeks, on my home PC, my work PC and and other peoples home PC's. Both windows updates and system restore are failing. [SOURCE]
We're only concerned with your Home PC.
Assuming Win7 64-bit with Internet Explorer 11 (IE11) installed...
We'll need to "dig a little deeper" here. Please answer each of the following[admittedly tedious] diagnostic questions in a correspondingly-numbered list in your very next reply, preferably
without quoting my post:
1a. When (approx. date) did you purchase the computer?
1b. Did Win7 64-bit come preinstalled on the computer when you bought it, did you do a clean install of Win7,
or did you upgrade the computer to Win7?
- What is the full name of your installed anti-virus application or security suite and
when (approx. date) does your current subscription expire? What anti-spyware applications (other than Defender) are installed? What third-party firewall (if any)?
- Has a(nother) Norton application or a McAfee application EVER been installed on the computer
since you bought it?
- Did a Norton free-trial or a McAfee free-trial [PICK ONE] come preinstalled on the computer
when you bought it? (Doesn't matter if you never used or Activated it.)
5a. Is KB3049563, KB3045171, KB3048070, KB3046002, KB3023215, KB3032655, KB3055642, KB3045171, KB3051768 and/or KB3061518 (and possibly KB2990214) listed in
Installed Updates (not Update History)? [1]
5b. How about KB3038314, KB3042553, KB3046306, KB3046269, KB3045999, KB3045685, KB3046482, and/or KB3037574?

8a. When (exact date) was Internet Explorer 11 installed according to
Installed Updates?
8b. What Update Version & KB number are displayed in the second line of text in IE11's Help | About [Alt+H+A] tab; e.g.,
Update Version: 11.0.99 (KB1231231) ?
8c. Is Firefox, Chrome or any other alternate browser installed?
- Are you in the habit of using "Registry cleaners" (e.g., Registry Mechanic; System Mechanic; RegCure; RegClean Pro; Advanced SystemCare; Registry Booster; McAfee QuickClean; Glary Utilities; AVG PC TuneUp; Norton Registry Cleaner; PCTools Optimiser; SpeedUpMyPC;
