Windows update don't update

Hello,

I am running Parallel Version 11.2.1 (32626) running Windows 7 Pro on a 2009 27' iMac running Yosemite 10.10.5.
Since a few months I have problems updating the Windows OS app in the Control Panel.
It starts donwloading but only after a few hours maybe 1 update has been loaded. I tried to left it running overninght but no success.
All internet connexion is working fine in the Windows system.
Any idea any one ?
Cheers

 

No one has a clue ? I am doing my 7th reboot, only 1 update after each other.... when is updates

 

Hi DenisB1,
Perform steps outlined at this link and let us know how it goes.

Thanks Dhana but both methods don't work.
