Recently i stubled upon this amazing collection which has a registry fix for almost every possoble file association in XP.
My regareds to dougnox for this collection
Here are the fixes

The files listed here are all ZIP files, which contain a REG (Registry) file. Download the ZIP and open it. Extract the REG file to your hard disk and double click it. Answer yes to the import prompt. REG files can be viewed in Notepad. Each of the REG files contains the default settings for the file extension indicated. For the ZIP file fix, the download is a REG file, since ZIP's aren't working anyway!

NOTE: If your EXE file associations are corrupted, it can be difficult to open REGEDIT, or to even import REG files. To work around this, press CTRL-ALT-DEL and open Task Manager. Once there, click File, then hold down the CTRL key and click New Task (Run). This will open a Command Prompt window. Enter REGEDIT.EXE and press Enter.

Image via CrunchBaseHow do you enable Registry Editing again if it has been disabled by your administrator?

Solution1

I found a way to get into the registry editor if it’s been disabled, here how you do it:

1. Disable as much as you can from your startup. Remove programs from your startup folder and such, so as not to lag down the bootup process.

2. Create a new shortcut on your desktop, point it to "C:\Windows\regedit.exe"

3. Log off, then log back on

4. As soon as you see your desktop, double click on the shortcut. The system does not check for policies until a few seconds after it booted up. If you click on the icon fast enough, it should let you get in.

After that, do all you need? After you close it though, it will not open unless you redo step 3 and 4.

Solution2

I found one vbs script to enable the registry editing. and below is the link.

The way to get into registry editing is simple. Open your start menu click Run and paste in the folowing command:
REGaddHKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f
