Virtualbox ‘error in supR3HardenedWinReSpawn’ on Windows 8

I have recently bought a desktop PC with Windows 8 on-board, and one of the first programs I installed was Virtualbox.

But unfortunately I’ve got a famous error ‘VirtualBox – Error in supR3HardenedWinReSpawn’ when running any virtual machine. In my case it was NtCreateFile error.

vb-error

Forums said that the error was introduced somewhere at version 4.3.14 and had to be fixed in later builds (current build is 4.3.28), but in the latest version I still observe the error.

Solution that worked for for me was uninstalling Windows update KB3045999 (to do that, go to Control Panel -> Installed Updates, find patch KB3045999, right click it, choose Uninstall).

Unfortunately, after some time Windows installed the update again, so I had to turn the automatic updates off.

What I tried and what did NOT help:

  • Playing with VirtualBox settings.
  • Downgrading to VirtualBox 4.2.* where some security features are not present yet.

Hope this helps someone.

Even better solution would be to use Linux 🙂

‘Unstage’ a file in git

I usually use a mix of command line and IDE GUI to run git commands. And today while trying to click Git Commit I accidentally clicked Git Add  for the whole folder including my IDE .idea sub-folder which I don’t need in my repository.

So I had to ‘unstage’ the content of the .idea sub-folder.

The operation is opposite to git add  and is called git reset. The parameter is the file (or directory) which has to be ‘unstaged’.

git reset <file>

In my case it was:

git reset .idea
