Control Panel will not open in Vista

1) Launch services.msc from a run command
2) Find the SLUNotify service & stop it
3) Find the Software Licensing service & stop it
(it may say that ReadyBoost needs that service to run; stop it anyway)
4) Restart both services, starting with Software Licensing

5) If you have access to the Start button, just type regerit in the Start Search field and hit enter
If you don't have access to the Start button, then you will need to run the regedit.exe from the CMD window.

Once you have the Registry Editor open, click 'File' and select 'Export'.
Name it 'RegBackup' and save it to your desktop.
If there are any problems, you can double click this files and your Registry will reset back to how it is right now.

In the Rgistry Editor, expand 'HKEYLOCAL_MACHINE'
Then expand 'SYSTEM"
Then expand 'CurrentControlSet'
Then expand 'Services'
Now, find (and click on) 'slsvc'

You should see 13 entries. I would like you to look at the "Description", "DisplayName" and "ImagePath" entries and compare them to what I list below:

Name Type Data



Are all 3 of these Entries visable in your Registry?
If so, do they exactly match what I have listed?
If not, what is different?

6) Restart the computer in safe mode and create another user account.
7) Many of Vista’s Control Panel tools are found in CPL files in the Windows\System32 folder. Using the Control Panel command-line shortcuts, you can launch any of these CPL files using a command formatted as follows:

control tool.cpl

Where tool is any Control Panel tool on your system that still has a CPL file in the Windows\System32 folder.

8) cut all the cpl file and saved on desktop, then try to open control panel. If open then the issue is with the cpl file. Might be one of the cpl file has corrupted. Need to check which cpl file create problem. Ten more useful .CPL files

1. Appwiz.cpl (Programs and Features replaces Add or Remove Programs)

2. Collab.cpl (People Near Me)

3. Firewall.cpl

4. Hdwwiz.cpl (Add Hardware Wizard)

5. Intl.cpl (Regional Settings)

6. Mmsys.cpl (Sound) Also Setasio.cpl. [NCPA.cpl] (Network Connections - see above)

7. Powercfg.cpl (Power Settings)

8. Sysdm.cpl (System Properties)

9. Telephon.cpl

10. Wscui.cpl (Windows Security Console)

9) If still face the same problem then repair or reinstall the operating system
