Problem with windows defender

ONIFADEmohamed asked on

Windows defender has been desactived on my computer and I don't know how. Then when i want to activate windows  defender a windows is opened and write:

windows ne parvient pas a acceder au peripherique au chemin d'acces ou au fichier specifié . Vous ne disposez peut etre pas des autorisations appropriées pour avoir accès a l'élément.

Que puis je faire . Puisque c est la seule protection sur le pc et je suis le seul utilisateur.

Error message translated by Bing:

Windows cannot access the device in the path or file specified. You have may not be the right permissions to access the item.

1. Did the computer come with Win10 preinstalled, did you do a clean install of Win10, or did you upgrade a Win7 computer or a Win8.1 computer [<=PICK ONE!] to Win10?

2. Who manufactured the computer (e.g., Dell; HP; Acer; Lenovo; ASUS)?

3. Has a Norton application or a McAfee application EVER been installed on the computer since you bought it?

4. Have you ever run the Norton Removal Tool and/or the McAfee Consumer Products Removal Tool?

5. What Version & OS Build of Windows 10 is currently installed?

  • Press & hold the Windows Key and press the R key. In the RUN dialog, type WINVER and press the Enter key.


You will find French-language support for Windows Defender in this forum =>

PS: There are indeed people who understand French here, despite my colleague's rather xenophobic comment below.
