The first solution worked. Thank you ever so much. You saved me a lengthy, expensive, and probably fruitless support call to Microsoft.

None of these options worked for me.
What did work was to create a new login and no more error messaages were generated.
Then copy all of the users files to the new profile
Bingo, all good

I spent a lot of time trying to fix this problem. it turns out it started when I uninstalled Google Chrome which apparently leaves code on the comoputer when renders links in emails/documents inaccesible. If you had installed/uninstalled chrome, you need to put it back and set your default browser to internet explorer and the problem will be solved.

The problem started when I uninstalled Norton antivirus from my computer. When I clicked My Computer for Properties it did not work. The restriction message popped up.
Then when I have looked for control panel it has vanished.
Your instructions to solve the problems are very user friendly than that of Microsoft. Really helpful.
The Solution 4 worked for me. The control panel has now reappeared in my computer and now I can access properties panel on clicking My Computer. Thanks for publishing these userfriendly solutions that any one can work on.

When clicking on a hyperlink in an e-mail, I get this Message : “This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.” I get this message every time that I attempt to use the hyperlink. I am the administrator on this stand alone computer. How do I deactivate this feature so that I activate hyperlinks ?
This is not an Outlook error. The most common cause is a corrupt registry key in Internet Explorer. The registry key found at
HKEY_Local_Machine\Software\Classes\htmlfile\shell\open\command
is either damaged or corrupt.
To fix it, try resetting Web settings in Internet Explorer. If this does not resolve the issue, set IE as the default browser following the steps in Set Program Access in Control Panel. If you use a different browser as your default, you need to set IE as the default until you verify the links work in Outlook.
uninstall Chrome
In addition to Chrome and Firefox, other HTML rendering and editing programs may take the HTML open command and cause this error. Greg reports UltraEdit is one such program.
If you received this error after uninstalling any application that takes over the HTML open command
(including, but not limited to, Chrome & Firefox browsers) you may also need to change the HTM/HTML
association in the registry.
1.Start, click Run, type Regedit in the Open box, and then click OK.
2.Browse to HKEY_CURRENT_USER\Software\Classes\.html
3.Right click the value for the .html key and select Modify…
4.Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
Repeat these steps for htm and .shtml keys if they exist. You may also want to check the xhtml and xhtm keys.

This massage I received in the MS Word while opening a page number link in the Contents.
None of the 4 solutions worked for me.
However, if I install Google Chrome, everythink is OK again. Changing the standard browser to Firefox (I do not use IE!!!) and uninstalling Google Chrome the problem appears again.
Any solution by anybody? (do not propose to keep GoogleChrome, I like Firefox!!!)
Stefan.

Solution 4 worked without having no problems.
I just opened the register, used the CTRL+7 for search, typed in ‘nocontrolpanel’ and changed the value to 0. Actually there was no value whatsoever.
Hyperlinks back to normal on Firefox.
Thanks!
