At some point in time you might get to the point where you notice that you PC is getting warm and the ventilator is running continuously ?


If you start to investigate it using the Task Manager, you will see that the CPU runs high on the svchost.exe  process?

But what does it mean ?


If you right click the svchost.exe you can select Go to Services …


It jumps to the services Tab. And highlights all related services linked to this process …


Once of them will be the wuauserv Service which is running.

Stop the Service and you will see the CPU drops immediately.


Next use the steps below to resolve the root cause of the issue.

Run as Administrator
net stop wuauserv

net stop bits

rd /s /q %windir%\softwaredistribution

net start bits

net start wuauserv

wuauclt.exe /detectnow

If this does not help install the once below :

I tried many other things, but no success … Sad smile


Finally this one did the trick ?


After installing and reboot it got stuck on this ? Sad smile


Solution :

Do a hard stop (press the power key to shut down) and restart in SAFE MODE


Once restarted I logged on again, and ‘voila’ Smile


The updates started coming in Smile Smile

November 13, 2016

When connecting using a Windows 10 Home Edition I got this message :

The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.
