How can I manually add Control Panel 's Accessibility Options in micro WinXP?

Hi everybody
I have micro Xp by experience, a very light version of XP.
I want to add Accessibility Options in Control Panel(for the 'mouse keys', to use keyboard to control the mouse).
I added the file 'access.cpl' in my Windows\System32 directory and the icon (of Accessibility Options) was added in the Control Panel.
So now I can start the Accessibility Options.
But the settings do not get stored.
In the Windows Registry I put the key:

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Extended Properties\{305CA226-D286-468e-B848-2B2E8E697B74} 2]

With the value(among others):

Code:

"%SystemRoot%\\system32\\access.cpl"=dword:00000007

But still the checkbox 'use mouse keys' does not get saved and the mouse keys do not work.
How can I manually restore the Accessibility Options?
Should I copy any other file except 'access.cpl'?
Or something else?

some pretty good instructions above.

 

Well as I mentioned, it's not the standard Windows XP but a 'slim' version.
So the 'Add/Remove Windows Components' does not work.
I 'll have to install the files manually.
Maybe you know which files?

 

I also have the same problem in a totally 'normal' XP which was 'thined' by enlite.
Enlite is a tool for making your XP light.
It removes some things.

 

have looked through several sites and cannot find one that specifies which files you need, but if you do find out which ones you need I can upload them to my onedrive account and then you could download them. pretty sure that it would not matter if mine are from a sp3xppro setup.
