Re: How to fix 0xC0000005 exception in Postgres 9.0

having chased this error several times over the last 20 years, if its not
windows update, AV update, firewall config change, UAC or a driver update
it is nearly impossible to to figure out what is causing it.

One can try to run sysinternal app such as process explorer or depends to
look over the files see if there are recent changes
https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

Process explorer i have seen crash postgresql when it tries to monitor
the internal workings so it can be very dangerous to use,

I have learned if the root of the problem can not be quickly identified in
an hour or two, its faster to just start from scratch, format the server,
install windows, and recover from backups. That is how frustrating this
error can be to track ..
