hello everybdy


plzzz kindly read the following paragraph

"Restrict Applications Users Can Run (All Versions) Popular
Category: Home > Security
Windows gives the ability to restrict the applications that can be run by users on a workstation.

Open your registry and find the key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer]

Create a new DWORD value and name it "RestrictRun" set the value to "1" to enable application restrictions or "0" to allow all applications to run.

Then create a new sub-key called [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer\RestrictRun] and define the applications that are allowed. Creating a new string value for each application, named as consecutive numbers, and setting the value to the filename to be allowed (e.g. "regedit.exe").

Restart Windows for the changes to take effect. "

my box has winXP pro ,, with PIII,128 MBRAM,20 GB HDD,
i have created one admin account,, one restricted acc ,,and one common for all (guest),,,
now i folowed as per the above para instructions ,, as it is written tht current user and if i'm using my admin account then tht tantamounts to tht i will lock myself of opening regedit.exe(if i use regedit.exe as the application to stop from executing..) so then i go to my guest account ,, and go the above mentioned key and try to create a new DWORD value but to my suprise it doesnt write to the registry giving the pop up message " error writing to the registry "
now i'm in a fix as to how to stop the other users from executing regedit.exe using the above method...
any help is highly welcomed
thanx in advance
