Kernel_security_check_failure

Real quick I cannot find that SFC repaired stuff.

(When somebody else has your stage name, add another digit. I don't have to tell you that. When somebody has mine, usually it's ME.)

Not much chance I'm going to remember such a change

Other than your stress on Driver Booster, what category of programs do you mean - in general - for me to avoid?

Programs that claim to speed up things a few 100% percent, like Advanced SystemCare claims to speed up several things a few 100% percent what is just impossible.
There was recently a thread created for a discussion about programs to avoid, but I cannot find it back unfortunately.

There is a program I/we recommend as long as you're very careful with certain features like registry cleaning, Ccleaner.
Ccleaner does what it says, but it does do nothing more and that is what most programs do wrong, many want to do too much causing problems.
With Ccleaner you can cleanup certain places, cleanup cookies, have an overview of all tasks, restore points, etc.
Many don't find Ccleaner a proper tool, but I would say it is the best you can find on the internet that does its job proper and nothing more.

Could this be my external drive?

Possibly, I did not find the right hard drive back so I cannot say with certainty.

Don't you degrade the drive every time you run scans?

Nope, hard drives are read/write devices. The scans read/write the drives.
With the right tools you can identify the status of the hard drive without causing problems, there are some programs who can cause problems but that is because of improper coding.

What is a paging operation?

You know what the pagefile is and what the purpose of it is?

Do you still want to have a conversation with him?

Yes.

Does software come with certain inarguable - or inherent - permissions?

The only permission software sometimes needs is administrator permission, with the standard settings programs ask everytime if you would grand them temporary permission for certain things. This permission is gone when the program is finished (when the program is closed).

I don't understand "inherited" permissions and were they passed on in the upgrade or created from scratch?

I hope my answer above answers this question?

I don't see a way to delete documents in my attachments file

I'll post some screenshots explaining how to delete attachments later :)

Axe0,

Something is new. I'm not happy and you won't be either. While trying to delete the folders in my attachments, I inadvertently turned off the "allow Flash now." Because I though it might interfere with my being able to see the instructions, I then refreshed, deleted cookies here and on FF, and reloaded several times, without success. I went to add-ons to change my settings to Always Allow. Of course, after I finished I forgot to change my settings back. I went to my inbox and clicked on something that used to cause the crashes ---and of course, I got a BSOD, kernel security error failure again. After the restart, I first fixed Flash settings back to "always ask." I checked Event logs which again reported the old error: "Update Windows license and product key tokens failed with 0x80070005." Then I ran wushowhide.diag. and hid the update again. After doing both, I went back and opened the mail which caused the crash and got through without any issues. I'm back to where I was last Friday. I'm certain that the CU didn't try and fail to install because the computer restarted quickly. I didn't create the log because you are working on last night's logs. I look forward to your response. (And I'll do it later.)

Before all this, though, I told you that I installed KB3156421 successfully. Turns out that it didn't. When I turned on my computer this morning, BitDefender notified me that it wasn't on. I manually opened it and watched it scan. It scanned the Cumulative Update. I thought a few things: Shouldn't this be whitelisted (or whatever)? It's odd that even with a couple of restarts last night, I did not get any notification that the update did not install until this morning, and that I should contact BD. Meanwhile, I found one forum where four people determined that BD & Win10 is iffy (only four). BD was quick and requested their diagnostic, which I sent a couple of hours ago.

Not that I wanted to bring this on me and my computer again, but you and I know that the way to determine which fix solved my BSODs was to turn Flash back on to "Always activate." I was fine not knowing. As this was determinative, you aren't going to be happy about this, either.

This morning, I also responded to another email from Anthony and told him that you wanted to talk to him, so the "intro," for what it's worth, has been made. Busy day.

Thank you.

What browser are you using, it is better to change the settings for Flash to let you choose when you want to load Flash (this is done by right clicking it and choose 'run flash player') because Flash is a great target for malware and you do not want to get malware.

I totally forgot about Bitdefender free version, it is not compatible with Windows 10, I forgot about it because I use the total security version. The best AV I can recommend for you is Windows Defender, I know you've had trouble with it but it is the most stable one that rarely causes problems.

For the pagefile I suggest that you read this tutorial, the first part describes what the purpose of the pagefile is.
The best setting for the pagefile in 99% of the situations = 'Automatically manage paging file size for all drives'
Virtual Memory Paging File - Change
In my words: if there is not enough RAM available for an operation, some of the data the RAM holds will be moved to the pagefile so the required space becomes available for the operation to be executed. The pagefile is on the hard drive, when data from the pagefile needs to go to the RAM it goes a bit slower because the speed of the hard drive is less than the speed of the RAM, this can cause a small lagging sometimes.
I hope you have an idea of what a paging operation is now :)

I live in the Netherlands.

Bitdefender support is not good at all, they deleted some of my tickets that I created a few days earlier but I did not get any support, but the products are great.

You get always a message from Windows Defender whenever you uninstall a 3rd party AV, you can safely ignore the messages :)
Windows Defender has indeed improved since Windows 8.1, I have personally not tested it because I don't want to take the risk of malware but I trust on the word of many users around.

I deleted many .exes in downloads. Why weren't those files cleaned out with Revo? That was many MBs.

Some are large indeed. You used Revo Uninstaller for what program exactly and what executables have you removed?

I can read the CBS log for a small bit, as the logs from DISM, if you would upload them.

After all we've done currently, what problems are still present?

Axe0- you missed the point. You forgot. Again: Win Defender stopped working and couldn't be fixed. That's the only reason I had to get another AV. For some reason, it fixed itself.

I did not forget about it, I only wrote what happens during the process of uninstallation/reinstallation of a 3rd party AV.

I needed something to permanently clean the Iobit programs you told me to uninstall.

Revo uninstaller removes all traces from a program, but it only deletes everything from the program and not from a company.

I asked you about whether using the programs for five months did damage that cannot be reversed without a Win10 refresh/reset/whatever.

I thought I'd answered it, anyway you can only revert back the changes without resetting/refreshing or clean installing with a backup or restore point prior the period of use. If no backup/restore point is available then there is no other way than (clean) reinstalling Windows or however one want to call it.

Wait~ you asked me to upload UAC screenshot/SFC results/ CBS logs. All those were sent to you. If you are now asking for something new - the DISM - then it is new. You already have them. Too much for you? Let me know.

The SFC result I mentioned in post #21, the UAC setting is similar to mine which is good.
DISM is mostly used when SFC cannot fix because of a corrupted source, DISM fixes the corrupted source so SFC can continue fixing the corruption, I did not mention it like that you need to upload it but only that I can read them a small bit. I said it because I thought you had new SFC results that said corruption could not be fixed.

The only tests pending are disk health. I ran Sea Tool (an excellent program) yesterday. Self-test and short generic passed.
Need more time to run long generic. Even if the long generic passes, do you still want me to run chkdsk?
If yes, and chkdsk also passes, do you still want me to run HDTune?
That's a LOT of disk checking and if all are required to get an accurate result, the next big diagnostic introduced to the world of troubleshooting would be to eliminate the need to run so many tests.

The long generic test takes indeed a lot of time, but it scan thoroughly.
Yes I would like you to run chkdsk even if the long generic test has passed.
Yes I would like you to run HDTune, HDTune provides a benchmark & health overview + a visual error scan.
With all the results I can much better say if a drive is or is not failing/faulty and if it is possible to fix any problem.
It happened a lot that chkdsk does not find problems & HDTune does not, but SeaTools does and the final result is a hard drive that could not be used anymore.
It also happened a lot that chkdsk and SeaTools could not detect problems, but HDTune could because the benchmark results were indicating a failing hard drive. A failing hard drive can be caused by the amount of bad sectors, health and/or the speed of reading/writing data, but it must be noted that if either occurs another one does not have to show problems which is why I would like to have results of all the tests.

THIS IS CRITICAL.
Axe, Axe, Axe - please read post 24. I can't believe you didn't see it.
Especially since you volunteer your time and expertise, you are great, and I appreciate what you are doing for me. You continue to ignore one critical question, which is at the root of my issues. When you read that post, you will be more up to date. Thank you

Could you be more specific please, I've read that post a dozen times but I cannot see what you want me to see specificly unless you mean the question about the Windows Update.

When I turned on my computer this morning, BitDefender notified me that it wasn't on. I manually opened it and watched it scan. It scanned the Cumulative Update. I thought a few things: Shouldn't this be whitelisted (or whatever)?

The answer for that question is, an update doesn't have to be whitelisted, any AV can scan everything present on the hard drive so it is not something to be worried about. If an AV sees it as a threat then there is something seriously wrong with the AV.
