So, I have this desktop for to fix for someone and it's behavior is really odd. It is running Windows 10 Pro.
To start, he said that for whatever reason, he said the only a few programs he has installed started 'acting up'. I was able to reproduce the problem of his iTunes software giving an error when it started, saying it needed to be reinstalled to fix it. Then it tries to repair itself and fails. But it does start and function.
He also said that all of the sudden windows starting asking him for a logon password. He has never had one on it. But I can not reproduce this problem since I have had it.
He also said that his desktop background got changed to windows 10 default, and he dont know how.
So, he thought it would be beneficial to try a system restore. All he told me about this was 'it wouldn't work'. When I tried to start a restore myself, is when I noticed something a little more deep is wrong. Just clicking on the Restore tab in system is when I get the Error code 0x81000202. I got this before in previous windows versions, so I go into services and start and set to automatic the volume shadow properties. But this does not fix it. Same error. Even after restarts.
So, in my digging, I get pointed to Microsoft forum saying to run the System File Checker (SFC). When I go to run it from an admin level command, it also gives an error that the program can not start. No reasons why.
These are the only actual errors that I get as far as messages or codes, so far at least. Below is just general unresponsiveness when I click to do anything...
There are some other odd behaviors. For instance, left clicking the start button (forgive my old school terminology) does not do anything. This means I can not get to any programs this way. I can right click it to get to control panel and go from there. Most things in control panel will come up. Run works from here. But the Search feature does not.
I can not find a single link to click to bring up windows update. The service was stopped but restarting it did change anything.
The whole thing is just kind of weird. Even more so sitting in front of it trying to troubleshoot. It is not slow or sluggish or like it is dying. The hard drive is not working to try and keep up. It is more like it has just 'had a stroke' and just plain has forgotten how to do some basic stuff and run some windows tools. Internet connection and websites seem to come up fine.
In what I have researched, I can't find anyone that has had these similar problems, outside of a virus infection. But, Avast, Malwarebytes and ESET all come up clean multiple times.
Any ways to fix this without a format?
Thanks in advance
