I have a vague memory of reading about a way to convert error numbers from a format like this -1073740791 to something meaningful. I am pretty sure it involved converting from a signed Int to something else, and that there was a way to do it in Powershell. But I can't remember enough details to get any results from a search it seems. Am I just missing some detail, or am I misremembering completely?

You can do the following to convert those numbers to more Google-searchable message/exception hex numbers:

• '0x{0:X}' -f -2147219694 # --> 0x80040712 --> E_UPDDEPLOY_REBOOT_REQUIRED
  A system restart is required to complete the installation. Windows Update Agent

• '0x{0:X}' -f -1073740791 # --> 0xC0000409 --> STATUS_STACK_BUFFER_OVERRUN
  Very generic error.. Can be caused by corrupted system files.
  See also STATUS_STACK_BUFFER_OVERRUN doesn’t mean that there was a stack buffer overrun
