NEW Block Installation In Progress

[kaka83]

Hello,
I have a problem with the SCCM software center.
I have a Windows update that crash but the software center tells me in the state "Installation in Progress ..."
How to stop the installation?
There is no setup process, nor msiexec.
I restart the ccmexec service - same

I am blocked
after restarting the PC, the MAJ went into failure, But several times the update continue the installation in progress ...

Is there a way to kill this installation

Thank you
