Comment re-activate Windows 7 après Windows has decided it is no longer genuine après an mise à jour?

[ForumBot]

Windows just récemment decided that it was no longer genuine and it keeps telling me that J'ai besoin de re-activate. Cependant, the dialog that pops up asking me if Je veux make it genuine seems to crash or give a fatal erreur: 0xD000006. J'ai cherché in Properties page for My Ordinateur dans le Windows Activation section and it simply says:

```
Status Not Available
Product ID Not Available

```

And il n'y a pas de option to activate. I'd prefer to not have to reinstall Windows 7, so any leads serait greatly appreciated.

J'ai essayé re-activating using `slui.exe` as suggested dans le answers below, but when I do that I get the following erreur dialog.

I'm not quite sure what to do maintenant and the thought of being on hold avec Microsoft n'est pas terribly appealing to me. Thanks.

Does the **Activate Windows** wizard (`slui.exe`) dans le Panneau de configuration work?

`slui.exe` has various options for activating a Windows license. Vous pouvez try re-entering your clé de produit by running `slui.exe 3`.

**Or** vous pouvez run `slui.exe 4` to activate by phone.
