No Device Manager

[Guest]

hi. it takes a long time for my laptop to load during start up so i deided to
run msconfig and selected Diagnostic Startup. i wasn't able to create a
restore point, unfortunately. when i tried to use winamp an error message
occured stating that i need to install a correct cudio device. this has not
happened before even if i choose selective startup or if i terminate some
processes in the task manager. i reverted back to Normal Startup in msconfig
and restarted my pc. however, the winamp problem still occured as well as on
other applications. i checked on Audio Devices in the control panel and it
says No Audio Device. I checked the Device Manager and it is empty: no
drivers, no hardware or anything. I tried running Help and Support in the
Start Menu but I got an error message stating that Help Support "can't be
loaded bacause some services are disabled". I would appreciate very much if
you can help me with this problem without reformatting my PC. thank you

Hello Crystal,

Device Manager empty:

Go to Start => Run and type in "msconfig" {without the quotes}
Click the Services tab.
Make sure that the 'Hide All Microsoft Services' box is not checked.
Make sure that the box for the service 'Plug and Play' is checked.
Restart the computer

If Plug and Play isn't listed:

Go to Start => Run and type in "services.msc" {without the quotes}
Scroll down and double-click Plug and Play. If you receive a
Configuration Manager message, click OK.
In the Startup Type list, click Automatic, and then click OK.
Close Services.
Restart the computer.

If the Device manager is showing the System Name but not showing any
devices, then check the security permissions on the Registry key

(Start => Run and type in regedit)

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\ENUM .
The SYSTEM account must have full control permissions on this key in
order for the Device Manager to list all the devices in the window.

To access the Registry, go to Start => Run and type in
"regedit" {without the quotes}
To check Permissions, right-click on the key

Another known cause is the Windows update KB905749 which is supposed
to fix a vulnerability in Plug and Play.

To uninstall an update:
With Explorer set to 'Show Hidden Files and Folders', go to your
Windows folder. Look at the blue text folders and locate the one for
the update. Open this folder and open the folder spuninst. There is an
uninstall executable in there.
