Compatibility mise à jour for upgrading Windows 7



This mise à jour performs diagnostics sur le Windows systems that
participate dans le Windows Customer Experience Improvement Program.
These diagnostics help determine whether compatibility problèmes may be
encountered when the latest Windows système d'exploitation is installé.
This mise à jour will help Microsoft and its partners ensure compatibility
for customers who want to installez le latest Windows système d'exploitation.

Said otherwise Microsoft uses your CPU and power to detect potential problèmes they may encounter si vous move to Windows 10 (or if they force you to move to this version parce que it suits they agenda for not loosing against Google and Apple smartphones OSes).

They scan your fichiers, and send the analysis vers leir servers. The problème is that utilisateurs who "*participate dans le Windows Customer Experience Improvement Program*" have seen their système slowed a lot avec e.g. 70% CPU monopolized by the MS scanner, a programme named `Compattelrunner.exe`. The latter can be launched on 100 or more concurrent threads.

At some point utilisateurs want to stop being used as Microsoft's auxiliaries at their own expenses and discomfort.

The usual way to supprimer an mise à jour, and prevent it from reinstalling is (details on [Microsoft's site](http://windows.microsoft.com/en-us/windows/troubleshoot-problems-removing-updates#1TC=windows-7):

- Switch Windows Mise à jour in manual mode

- Désinstaller KB2952664

- Reboot

- Get nouveau Windows mises à jour

- In the nouveau mises à jour "hide" KB2952664.

- Switch Windows Mise à jour back to your usual mode.

Problème: In some cases this ne work. As soon as the système is rebooted, the KB2952664 mise à jour is reinstalled automatiquement, in spite of it being sur le "hidden mises à jour" list, *even si vous are in manual mode*. Said otherwise it installs sans your autorisations. Some have filled a complaint vers le FTC (US [Federal Trade Commission](https://www.ftc.gov/)) to try and stop this:

Si vous really ne know what Powershell is, or ne have technical knowledge about Windows, ensuite c'est better you learn better going further. Powershell is a powerful tool to do anything sur votre filesytem and configuration, including harm.
