[problème] [Win 7] Restaurer des fichiers Windows

Salut,

J'ai perdu quelques applications (.exe) du sys. d'exploitation (Paint, Console de gestion...) suite à un virus et je cherche un moyen de les restaurer depuis le DVD d'installation.

Si ce n'est pas possible, est ce que quelqu'un qui utilise Windows 7 édition 32-bit aurait la gentillesse de m'uploader les deux fichiers (surtout la console de gestion puisque je ne peux même pas accéder au gestionnaire des périphériques) ?

Les fichiers sont:

1- Paint: "C:\Windows\System32\mspaint.exe"

2- Console de gestion: "C:\Windows\System32\mmc.exe"

Merci d'avance pour votre aide.

boot en console, et tape sfc /scannow

formater totalement ?

Quand la vérification s'est terminée, le message disait que Windows avait trouvé des fichiers modifiés mais n'a pas pu les réparer (Le dvd d'installation était dans le lecteur mais n'a pas été utilisé).

Jamais de la vie

A. The Windows Automated Installation Kit (WAIK) includes the Imagex utility, which, in addition to facilitating the capture and deployment of WIM images, can also be used to mount a WIM file so that you can access its content.

But before you can mount a WIM file, you need to install the WIM File System Filter, which is responsible for handling all file system requests to the mounted WIM file, enabling browsing and editing of its contents. To install the WIM File System Filter, navigate to the C:\Program Files\Windows AIK\Tools\x86 folder, right-click wimfltr.inf, and select Install. This will install and activate the wimfltr.sys file system filter.

After you install the WIM File System Filter, you can mount a WIM by following these steps:

 

1. Create a folder on the file system that will be used to access the WIM file content (e.g., d:\vistamount).
   
2. Start a command prompt with Administrative credentials (Start, Programs, Accessories; right-click Command Prompt and select "Run as administrator").
   
3. Navigate to the C:\Program Files\Windows AIK\Tools\x86 folder on a machine with WAIK installed (assuming you're running on an x86 architecture box).
   
4. Run the Imagex command with the /mount switch to open the WIM file in read-only mode or the /mountrw switch to open with full read and write abilities. Use the following command syntax: imagex or /mountrw> For example, to mount the first image of the standard Vista install.wim file to path d:\vistamount, use the following command:
   C:\Program Files\Windows AIK\Tools\x86>imagex /mountrw d:\Sources\install.wim 1 d:\vistamount
   You can then modify the WIM file via standard file system manipulation tools, such as the command prompt and Windows Explorer.
   Once editing is complete, unmount using the Imagex utility with the /unmount switch, and if you wish to keep the changes made also add the /commit switch (if you don't specify the /commit switch, all changes will be lost, and you won't be prompted for confirmation). Unmounting without the /commit switch is significantly faster because it doesn't have to convert file system changes to the relevant area inside the WIM file.
