Unable to install Cumulative Update for Windows 10 for x64-based Systems (KB3081448) - Error 0x80073712, so far some of the answers I read were very difficult to performed for a regular windows 10 user.

 

Nvidia Driver not working properly

Thank You for your prompt response, I followed your instructions to the letter, but driver did not respond accordingly, I downloaded successfully NVidia 9600 but did not help that all, Microsoft sent me an update for that driver but did not install, ( NVIDIA
driver update for NVIDIA GeForce 9600M GT - Error 0x80070103) If I disable this driver temporarily for this section I'm be able to work or write this comment to you without interruptions, but in order to have a stable system again after shut down I must reinstall
the driver prior exiting, I fully believe that Nvidia should work to correct the update programing of that 9600 , and Microsoft should be advised of the problem that we are experiencing with this windows 10 driver. If you think of any thing else I should
do please let me know. Thank You

 

Try this and see if it works. How can I share any files on my network ?
Also, try this, run command prompt in admin mode,
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc.exe config mrxsmb20 start= disabled
