I tried Microsofts suggestion of clicking on plug and play and making sure it was set on automatic but that didn't work.

Hello Estridge48,

Thank you for your post.  Try the following registry edit to resolve your issue:

  1. Go to "Start", "Run", and enter "regedt32"
  2. Maximize the "HKEY_LOCAL_MACHINE" window.
  3. Scroll down to "SYSTEM\CurrentControlSet\Enum"
  4. With "Enum" selected click the "Security", "Permissions" menu.

Note: At this point you will probably notice there are no permissions on this key.

  1. Click "Add".
  2. Add the group "Everyone" and the user "SYSTEM".
  3. Select "Everyone" and check "Read" ONLY!
  4. Select "SYSTEM" and check "Full Control".
  5. Click the "Advanced" button at the bottom of the window.
  6. On the Advanced window check "Reset permissions on all child objects..."
  7. Click "OK"
  8. On the warning window click "Yes"
  9. Close REGEDT32

Modifying REGISTRY settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of REGISTRY settings can be solved. Modifications of these settings are at your own risk.

Please let us know if  this did or didn't help to resolve your problem.

Cheers

    This was so helpful! I spent HOURS on this problem and this finally fixed it. I wanted to note that the language on the box I checked in the Advanced window (step 10) was different. It read "Replace all child object permissions with inheritable permissions from this object". Even though I got an error message after accepting ("Registry editor could not set security in the key currently selected or one of its subkeys") the device manager now works! It took a leap of faith to do this, but I'm glad I did.

    It did not work.  I keep getting the same two fixes that do not work.  Is my last solution a reinstall of the OS?
