System Restore did not complete successfully.

I have discovered how to disable KIS's Self-Defense. Its disablement window says: "By enabling Self-Defense you block all attempts to modify KIS files, memory processes and system records." So that seems clear enough. I have now downloaded MBAM's Clean removal tool.

I therefore plan to:

1. Disable KIS (I have found out how to do that);
2. Uninstall it using Windows Uninstall Control Panel;
3. Use MBAM's Clean removal Tool;
4. Restart the comp.;
5. Make another test Restore Point and attempt to restore to it;
6. If it is successful, good. I would need to go through all this every time I wanted to go back to an earlier Restore Point. A nuisance, but I have only ever actually needed to do that once in the 18 months I have been on Windows. (Or perhaps ditch KIS for another less-tropublesome alternative.)
7. If that's not successful, then, as MoxieMomma says, "grab fresh copies of the KIS and MBAM installers directly from the publisher's download web sites and reinstall", and go back to my step 4.

I plan to do this tomorrow. Two questions please:

a) Does this seem sensible; and:
b) Windows Defender is turned off by KIS. Should I check that it is enabled at step 4 (I guess Windows will do that automatically now that KIS is gone).

MoxieMomma: You said: "At the very least, the roll-back can break the program's ([KIS's] metadata. At worst, it can cause other corruption to break the program." I had a clean install of Windows 10 10 days ago and re-installed KIS, and MBAM. That went OK. Hopefully, they will again.

Many thanks to you both for your help.

EDIT: Perhaps I should delete my step 2, to let MBAM grab it?

Me again. SUCCESS! I used Windows 10's Uninstall routine to get rid of Kaspersky. (It took some time.) followed by an automatic restart. Then I checked that Windows Defender and Windows Firewall were on (the first switched on automatically after having been switched off by Kaspersky, the second had always been on). I created a Restore Point ("Test") and then created a new Word file in a folder on the desktop as confirmation. Finally I opened "Restore system files and settings " (in a Control Panel) and chose "Choose a different restore point" followed by choosing my recent restore point.

The comp. went off to do that and after an automatic restart I got the message saying that the restore had been done successfully. Whew! The new word file and its folder had disappeared from the desktop, which confirmed the restore.

Huge thanks to everyone. I would not have guessed that KIS was the culprit, especially because it did not give trouble before the Anniversary Upgrade. MS should give a list of such changes. The beta testing would certainly have flagged the KIS problem to the Insiders. Should I tell MS? Nah! Tin ears.

My system is now protected by Windows Firewall and Defender, and Malwarebytes (paid version). I have searched independent sites and all say that the first two are good nowadays and the domestic user, like me, can rely on them alone. Anyone disagree? (Malwarebytes gives extra.)
EDIT: The new Word file is still there. Perhaps going back to before it was created only affects computer setting. Correct? Anyway, the restore worked successfully (it said).

Just a side note ... I am running Windows 10 Pro with Norton Security Suite from Comcast. I have not encountered any problems with system restore or restoring a system image.

I think the Comcast version is a slimmed down version of the full Norton program so may not have self protection.
It could also be that Win 10 system restore is different to previous Windows versions so disabling self protection is no longer required.

My personal opinion:

I would not necessarily ditch the robust protection of Kaspersky for the unlikely, future, theoretical need to perform a system restore. The other 99.9999% of the time you use the computer, it offers what many would say is more robust security than WD.

The fact that KIS prevented the system restore with its system protection feature enabled suggests that..... well..... it does a good job protecting the system (and itself).

EDIT: AFAIK the inability to perform Windows System Restore with KIS enabled is not a "bug" in the strict sense. It has long been the case with many strong security programs -- not just KIS -- that their deep integration into the OS may interfere with System Restore and/or cause problems with the program when a roll-back has been performed with the program installed. FWIW, KIS 2016 MR1 with patch (e) and KIS 2017 MR0 are both fully compatible with Win10 1607.

The one step I don't think you tried would have been to disable KIS AND to disable the KIS self-defense feature (doing so involves merely un-ticking a check-box in the settings) before trying the restore??
If that had been successful, then you might have been able to perform the restore without fully uninstalling KIS.

AV and other security choices/strategies are highly personal, based on many factors.
There is no one "best" or "right" approach that suits all users and computers.
If you are happy with WD + MBAM, then that is certainly fine.

My own personal choice is that I prefer the protection afforded by KIS over that of WD for my daily computer use. In the unlikely event that a system restore might someday be needed, I am comfortable with knowing that I might need to uninstall KIS (or at least fully disable it and its self-defense) before doing so.
(I also run MBAM Premium and MBAE Premium for resident protection.)

>>In any event, I'm glad you were able to resolve your issue.

Just my 2 cents and worth less,:)

I'm wondering if you would have an easier time restoring a full image of your OS partition from a full image backup (located on any affordable, reliable, external media). My experiences with System Restore Points convinced me to begin and maintain a routine of making backups onto external media ever since my Windows 95 days.
