OS PROBLEM I am computer engineer, i don't understand how i can change the registry editor with the help of software

I think The default security provider in Windows XP has been changed loadTOCNode(2, 'workaround'); To reset the default security provider in Windows XP, delete the relevant registry keys in the Windows registry. To do this, follow these steps:

1. Start the computer. Press the F8 key during startup to start the computer in Safe mode.
2. Start Registry Editor (Regedt32.exe).
3. Delete the following registry keys in the Windows registry: HKEY_USERS\.DEFAULT\Software\Microsoft\Cryptography\Providers HKEY_USERS\S-1-5-20\Software\Microsoft\Cryptography\Providers
4. Quit Registry Editor.
5. Restart the computer

The issue or problem is caused by system drive letter has change or a software has changed the default security provider without knowledge of users.

To resolve the issue, change the system drive letter to revert it back to original value, or match the new drive letter to the security provider. If the default security provider has been changed, reset the default security provider in Windows XP by deleting the relevant keys in the registry.

Reset the Default Security Provider in Windows XP

You will see a few Provider key beneath the branch. In each Provider key, edit the Image Path value to match the new drive letter.
Exit Registry Editor.
Restart computer.

Reset the Drive Letter of the System Drive

Use Registry Editor to change the drive letter of the system drive back to its original value. Edit the following registry key to change the value of the system drive:

HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

where \DosDevices\C: and other values presents the drive letters.

Unless you have a back up of your original registry, there is nothing you can do..

sorry

windows vista has a thing about admin rights and you can check every box and it says you have rights but you really don;t.
and there is now significant admin user in vista anymore.
here is what i had to do to get the rights to do anything.
Please understand that editing the registry is not for the weak computer person and you must be able to reverse any changes made that cause an issue. I used this on mine and it helped me gain some control.

click start and run,
type in regedit
when Registry editor opens
click on HKEY Local Machine
click SOFTWARE
click MICROSOFT
click WINDOWS
click CURRENT VERSION
click POLICIES
click SYSTEM
HIGHLIGHT SYSTEM
in the area where there are values right click and select new/ DWORD
enter "EnableLinkedConnections"
press enter
right click EnableLinkedConnections and chose MODIFY and change the value to 1
Save and exit Registry Editor.
Reboot your computer and try Burning again.

It sounds scarey but it's not and just remember or write down these instructions so you can refer to then easy during the process.
and also to reverse the entry if needed.
if you need any further help let me know.
Good Luck

Apparently MS in their infinite wisdom decided that in vista they would take the power away from the user and remove the administrator from the equation.
So no matter how many thing your try in the user accounts you will not get full admin rights.
but here is a reg hack that worked for me real well. I am running windows vista home basic

Click Start and Run type in regedit and enter
your now at the registry editor.
click and expand HKEYLOCALMACHINE
go down and click SOFTWARE
click MICROSOFT
click WINDOWS
click CURRENTVERSION
click POLICIES
click SYSTEM
you will see the registry entries to the right
right click in the white area and select new DWORD
Name it "EnableLinkedConnections" and enter
Right Click on EnableLinkedConnections and choose MODIFY change the Data Value to "1"
Save and exit Registry Editor
Reboot your computer and try deleting the folder you wanted to again.

WARNING:
Using this reg edit you are changing your registry and could develop problems if you don't do it correctly. Be Warned and do some research prior if you need to understand registry editor.

Are you the Administrator, and do you have the Administrator's password?

If so, then log in as Administrator and make the necesary changes.

However, if not, then you must reinstall the OS, to establish yourself as such.

The cause of the error is a problem with the Microsoft® Windows® Installer program used by the software. It produces the error when the registry entry AllocateCDRoms at the following subkey is set to a value of 1.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Additional information about the registry is also contained in the Help topics in the Microsoft Registry Editor.

Start the Registry Editor and locate the following subkey:

Hi karthee,

Every version of Windows since Windows 95 has used a Registry, which is essentially a database containing the configuration information for the OS, its peripherals, and any installed software. The Registry is among the first things that Windows loads at startup, and it tells the OS everything from how menus and the Desktop should look and feel, to where all the vital files and programs reside, to which hardware is installed on the system.

The Registry actually includes a series of data files stored in different folders in your Windows subdirectory, all according to which OS version you’re using. For instance, in WinXP Home or Professional, the Registry has six files located in the Config folder at C:\WINDOWS\SYSTEM32\CONFIG. Win98 SE and WinMe have different files in other locations, but in all cases, it’s easier to access the Registry via the Registry Editor.

The Registry Editor, the Regedit.exe program, resides in the Windows subdirectory. But the quickest way to open the Registry Editor is to click Run from the Start menu, type regedit in the field, and press ENTER.

Now that we told you how to open the Registry Editor, we should also warn you that it’s unlike other Windows programs because it saves any changes you make on the fly rather than waiting for you to decide to save your changes. Yes, the Registry Editor will save any changes you make as you make them and apply those changes to the respective files and settings on your system. You cannot negate your edits or deletes simply by bailing out of the program without officially saving anything. This means that any user venturing into the Registry Editor must take special care to track any changes made and protect him or herself by backing up the Registry before tinkering with it.

Hope it's help's you.

Enjoy!

Hope to hear more from you soon

tnx
