Windows machine experiencing sudden shutdowns/black screens and erratic behaviour : KB3025096 package is not getting installed/corrupted files; 0x800f0805 Windows update error

Question

After we collected the logs from the Windows machines, like UC Engine/NUCs, we discovered the same error on seven different sites, which is causing weird behavior on these machines and causing user inconvenience,and questioning the reliability of the system. What should be our next steps to rectify this? Without actually re-imaging these machines, how can we get rid of the above-stated issue? Looking for some help. Thanks

Hello,

For the shutdown unexcepted issue, I suggest that you could check the system event log to find related event information about shutdown. Check if the unexcepted shutdown issue caused by a BSOD or some system process shutdown the machine. At last you may analyze check the dump file.

For the update issue, few steps below you could check:

The error code 0x800f0805 generally means that there’s corruption in the system files or the Component-Based Servicing (CBS) manifest is corrupted. Here are a few methods to fix this issue:

Method 1: Use Windows Update Troubleshooter

Press “Win + I” to open Settings.

Go to “Update & Security > Troubleshoot”.

Click on “Additional troubleshooters”.

Click on “Windows Update” and then “Run the troubleshooter”.

Method 3: Perform a DISM scan

Open Command Prompt as Administrator.

Type “DISM /Online /Cleanup-Image /RestoreHealth” and press Enter.

Method 4: Reset Windows Update Components manually

Open Command Prompt as Administrator.

Type these commands and press Enter after each:
