Remote Desktop Crashes with printer related errors.

Has your Remote Desktop Server been crashing a lot for the last 2 weeks?

It’s probably because you have recently installed Windows Update KB4541329. In my environment, this caused anyone with a redirected printer to receive frequent app crashes, notably in Excel and Outlook. Checking the Event Logs revealed a lot of print spooler and winspool.drv errors.

Following this I also discovered that clicking ‘Device and Printers’ would crash Explorer.exe repeatedly.

Resolution

Simply uninstall the update from appwiz.cpl and and reboot your server. On my servers this took a good 15-20 minutes with 100% cpu utilisation.
