Hi Jodi,
quote: "I renamed Renamed pcmcia.sys to pcmcia.sys.old - Rebooted windows."
After you rebooted and the network adapter and other devices work again, have you renamed the pcmcia.sys.old back to pcmcia.sys? In my case, renaming the pcmcia.sys.old to the original name made my pcmica card functional again and windows (funnily) did not run into the previous device manager issue. For the moment, my system is running winversion 1803, the pcmcia.sys is present (re-renamed), everything runs well and I am now waiting 6 months, how it works with a new major update.
If you go through the update process and installing several major updates in a row, you could check whether the re-renaming after the first update runs fine with the next update you do. Presumed you do such kind of update process.
However, it seems clear that renaming pcmcia.sys to pcmcia.sys.old without re-renaming just presents a temporary workaround - which actually I personally can live with.
Best Regards,
Sebastian
