Explorer Right Click Context Menu Items Missing

context-menuextensionshellwindows-explorerwindows-xp

OS: Windows XP Service Pack 2
When I right click on a file/folder most of the third party context menu items are missing.
These are the items like 7zip , Unlocker, Winamp … which adds entry to right click context menu.
What could be wrong?
I checked HKEY_CLASSES_ROOT*\shellex\ContextMenuHandlers and they don't seem to have items added with any of these third party installs.

If you don't need them I would start uninstalling the programs that put the shell extensions in. Aftermarket shell extensions can wreak havoc. Smearp has a good idea too but I am not familiar with that product (it does look good though).

Also, when you have shell issues re-installing the latest service pack can often solve many problems.

In your case, installing SP3 might fix the shell. Plus, in general, it cant hurt (unless the install goes bad which is rare).
