ACAS \ Nessus Causes Systems to Crash, Reboot, or BSOD upon Credentialed Scans

Issue:
ACAS \ Nessus Causes Systems to Crash, Reboot, or BSOD upon Credentialed Scans
Environment:
Windows 7 workstations
Symptoms:
The moment an ACAS \ Nessus Credentialed scan begins, the target system crashes, reboots, or BSODs.
Solution:
Tracked this down to Microsoft Patch 3161531.
Appears to be happening when Tenable accesses C$ (almost immediately upon scan).
A related discussion on BSOD's when accessing C$ is here:

It appears that Microsoft has put out a related hotfix to this issue. Not because of Nessus specifically, but due to general problems when accessing C$, which I believe is ultimately why Nessus is failing.

Updates not working on new install of Windows 7

Issue:
Updates not working on new install of Windows 7
Environment:
Windows 7 x64 Fresh Install
Symptoms:
Going to Windows Updates results in a window which states 'Checking for updates', but that check never ends.
Solution:
I did see this solution after much looking on answers.microsoft.com , but wanted to put it here as it specifically worked for me:
Install Windows 7.
Don't connect to internet.
Install Windows6.1-KB3083710-x64.msu.
Reboot.
Install Windows6.1-KB3102810-x64.msu
Reboot.
Use the Windows Update tool as normal. The initial check for updates may still take some time, but should eventually work.
