On Tuesday of this week, I had 12 critical /important updates from Microsoft. I left the computer to install them " all in a oner " and it appeared that they installed correctly but I have spent the last couple of days having to do repairs and Windows has loaded files like what seems like forever. I think that my computer is now running ok but I wondered if it is best to install updates one at a time instead of installing multiple updates all together. I should be very grateful for your advice.
