WSUS MMC Crashes and WSUS Generally unreliable.
Application Pool "WSUSPool" Stopped in IIS
To improve WSUS availability, you need to increase IIS Private Memory Limit. The default limit is set to 1843200KB. And when an IIS worker process uses more than 2GB WSUS crashes and the problem occurs.
Change Private Memory Limit (KB) to a higher number that fits your server specifications or simply 0 , which means no limit, instead of the hard-coded 1843200. Follow this path to find the setting:
WSUS Application Pool IIS Advanced Settings
Internet Information Services (IIS) Manager → Server → Application Pools → Select “WSUSPool” → Actions Advanced → Recycling → change “Private Memory Limit (KB)“.
This’ll improve WSUS availability.

Sometime Windows Update on Windows clients wont sycronize with your WSUS server, or wont download an update that recently been pushed out.
If that happeneds try this:
net stop wuauserv
REG DELETE "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v LastWaitTimeout /f
REG DELETE "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v DetectionStartTime /f
REG DELETE "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update" /v NextDetectionTime /f

If outlook keeps opening in Safe Mode, this could be due to a KB Microsoft pushed out (KB3114409). This was removed by Microsoft as it did't work as expected.
To resolve the issue remove the KB from the client machine. If there is a WSUS server on site it will also need the update Approving and the Approving for Removal. Set a deadline to make it happen ASAP.https://support.microsoft.com/en-us/kb/3114409
