I am trying to fix up my parents computer that is running Vista Home Premium but I can't get the Event Log Service to start, and as a result, Task Scheduler won't start either, nor will any of the services that require Task Scheduler in order to work, like defrag. Not sure if it is what is causing System Restore to not work as well but it isn't working either.
System Restore appeared to be working as programs like Revo can make restore points, but I cannot make one manually and of course, it doesn't make the scheduled restore points due to Task Scheduler not working. I did not notice that I couldn't make restore points in System Restore until after I ran the Windows Repair from Tweaking.com.
The Windows Repair program caused some problems so I went to use System Restore only to find that Windows Repair program had deleted all of them, even the one I told the Windows Repair to create wasn't there. That program also caused some other problems but thankfully the registry backup I had it make was there which helped me resolve the problems it created. It was then that I tried to make a restore point and found I could not do it.
In any case, I am left with my original problem of the Event Log Service not starting which I need to have running in order to have the Task Scheduler work. Both are set to automatic in services but neither will start. When I try to start the Event Log Service, I get a Error 1747: The authentication service is unknown. When I try to start the Task Scheduler I get Error 1068: The dependency service or group failed to start.
Everything else seems to be working fine and it appears that the problem with the Event Log Service may have been caused by the updates that windows did on the system June 19, 2016 as that is the last time there was anything written in the events log.
I have thought about uninstalling the dozen or so updates that were installed that day, but not sure if that would fix it, even if it was an update that broke it.
I found online that some people have had a problem with the Event Log Service and were able to fix it by resetting the winsock, but their problems seemed to also involve the internet, which mine do not. Nevertheless, I tried it but it didn't work.
I also tried just disabling the Event Log Service and restarting the computer, then resetting it to automatic and restarting the computer, but that didn't work either.
Does anyone have any ideas how I can fix this?
Thank you for any help anyone can give, it would be very appreciated
