Device Manager - Empty!!

[mistergixer]

O/S W7 x64

When I open device manager, it is completely empty, there are no devices listed in it all.

It doesn't matter how I filter the views (type, connection, resource etc), still nothing shows.

This has been happening for a while, and I never bothered with it. But I've recently installed new hardware, and it would be nice to be able to update drivers etc through DM.

Any ideas??

I had this before and tried all the suggestions from google etc to no avail, the following post is from another forum and fixed it, bit of a pain but better than reinstalling windows..


1. download the subinacl.msi file from the following link and save the installation patch on the Desktop:

(do not worry that it does not list your OS still works)

2. go to the Desktop and double click the downloaded file.

3. select the C:\Windows\System32 folder as the Destination Folder during the installation. Later we will use this tool to reset the permission settings on the current machine.

Note: If UAC (User Account Control) window is prompted for permission to continue, please click "Continue"

4. Click "Start". In the Start Search bar, type: "notepad" (without quotes) and press Enter.

5. Copy the following commands and then paste them into the opened Notepad window:

@echo off
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f
subinacl /subdirectories %windir%\*.* /grant=administrators=f
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f
subinacl /subdirectories %windir%\*.* /grant=system=f
@Echo =========================
@Echo Finished.
@Echo =========================
@pause

6. After the above commands are finished, close the Notepad window. Choose Save when you are prompted to save the file. Type "reset.bat" as the file name and choose Desktop from the left panel as the save location.

7. Refer to the Desktop and right click the reset.bat file, then choose "Run as administrator."

8. You will see a DOS-like window processing.

NOTE: It may take several minutes. When it is finished, you will be prompted with the message: "Finished, press any key to continue".

Now we will reset your user permissions:- log in as your normal user

Go to start, all programs, accessories and right click on command prompt select "run as administrator" command prompt will open I have done this on my computer and you will see the commands I have input YOU will need to substitute your user for mine Vistatest\Paul, run them in this order syntax important, press enter after each one (you should see the SUCCESS as shows here) The commands are in RED the return in BLACK
