I usually don't receive the cumulative update until the morning after patch Tuesday. I turned my laptop on this morning, made my morning cup of coffee, and did a few other things. By the time I was finished, I checked and the cumulative update had installed and was ready for me to restart my laptop.
It took a little longer than usual (about 20 minutes) and then I was on my desktop as usual. I figure that it included some updates to make Windows 10 more secure among other things.
I don't know how many people that come to this community forum, but I thought I would give this valuable information/tip which might just save you from receiving those errors.
An MVP friend gave me this tip several years ago and it had to do with registry cleaners. I made the mistake of using a very popular one once. It was around 2009. The registry cleaner got rid of important files, and I no longer had volume/sound or a mouse. I had to power off and quickly push on F4 or F12 (I can't remember which) where it would bring up the screen that could correct those issues.
I've never used a registry cleaner since then, and I don't have any problems with the cumulative updates either. My friend told me that a registry cleaner could cause all kinds of problems and might even introduce a malware onto your operating system. You also don't save much space by using one either.
What I'm going to share is from Wikipedia and it's about registry cleaners. If you don't want your operating system to mess up, then don't use them. Period.
