Delay updates in Windows 10

On more occasions Microsoft released Windows 10 updates that disabled the network connection, the webcam or caused other inconveniences. Windows 10 automatically downloads and installs the updates without asking for permission from the owner of the computer. In Windows professional you can delay the installation of updates, so your work is not interrupted with frequent recommended updates, and Microsoft can fix the update before your computer installs it. The important security updates are still installed when those are released.

Visual Studio 2015 is very slow on Windows 10

When I have upgraded Windows 7 my computer to Windows 10 I have also installed Visual Studio 2015 professional. From the first moment Visual Studio 2015 was very slow. My computer was freezing all the time.

I have read many articles about the slowness of Visual Studio 2015, but I cold not find anything that helped, so I have decided to switch back to Windows 7. Unfortunately after the downgrade process my computer did not boot anymore. Finally I had to reinstall Windows 7 and all my applications. Luckily all my files were on the hard drive, so I did not lose anything.

Since that, I have found the following recommendation at

  • Uncheck [Tools->Options->General->Automatically adjust visual experience based on client performance]
  • Uncheck [Use graphics acceleration if available]
  • You can leave [Enable rich client visual experience] checked

Sooner or later I will have to bite the bullet and install Windows 10 again, hopefully by that time Microsoft corrects this very serious problem, or I will try these steps to make it work.
