Excuse me for this mess, started to quote your message and answer as I came to the next question, WRONG! Will attempt to answer them as I read them below.
Vista came installed on this system, not an upgrade, except just a couple of days ago did upgrade from SP1 to SP2. This was happening before that upgrade. Never have had any other O/S on here.
Confirm CIS only security App not shown with ICON in SysTray and AV and Defense+ not doing any alerts. If I click on the CIS under Start/All Programs/Comodo Internet Security/Comodo Internet Security to bring up the control center the ICON will be displayed and when closing down as reported previously Windows will still report it is blocking some programs from starting and I can start it if I like or remove it, which I usually START it; except when closing down my system. Not able to grab any screen shots as the only time, most of the time, it will show it’s ugly notation is when closing down for the day. Maybe if it will show again normally that will be done, screen shots, other wise if I do a continuous search for info on that at either µSoft (Microsoft) or on the web there may be some info that I can get for you.
Yes, it can be reproduced every time my system is restarted, usually daily or maybe a short number of days depending on my other functions or Honey Do’s from my spouse, I am retired and my only real job is keeping house, doing meals and taking care of my Wife.
As for other security applications installed; avast! Antivirus, (the following are not auto starting) SUPERAntiSpywareFreeEdition, HijackThis, Spybot - Search & Destroy/w TeaTimer (TT is an autostart program); the last three are only run when I feel a need (less Tea Timer of course).
Comodo Internet Security/w Defense+ Product version : v3.10.102363.531, Virus Signature Database Version : 1608
The common phenomena dating back to Windows 2000 may be true for some systems, but; this is the only O/S ever on this computer, Automatic Login is not used, will attempt a logoff and back in again to see if that will do any good. Not connected to any network, only the internet by hard wire. I am joining the club “nobody has a clue what’s happening.” As for the provoked, I have been very nice to this system and that has not helped and even some what nasty which did not help either.
Just clicked on Even Viewer and Windows presented a box:
Consent UI for administrative applications stopped working and was closed
A problem caused the application to stop working correctly.
Windows will notify you if a solution is available.
NO information on a solution for that problem nor the one below.
(RED Circled White) “X” with C:\Windows\System32\eventvwr.msc
File system error (-1073741790).
I have had that error code before with attempting to start other programs and did a search on Google that shown several other error codes that did not match what I had, NO HELP! So what that means is the Event Viewer will not come up for me to review at this time. Maybe with a reboot it will work.
I will end this here and check out the links you have provided as they seem to be rather lengthy and I am a slow reader.
