The problem was faced by one of our readers who faced the following error message whenever he clicked on a drive to open it and see the contents.
“This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator”.
Cause of the problem:
The problem is confirmed to be caused due to change in the default web browser or the Internet Explorer.
Steps to fix the problem:
You can try following solutions and see which one fix it for you.
Solution 1:
• Go to Control Panel -> Add Remove Programs, click on Set Program Access and Defaults.
• Open up the configuration whichever is selected and change the default web browser to something else.
Solution 2:
• If you use older versions of IE then upgrade it to the latest one.
Solution 3:
The problem can be caused due to the corrupt or damaged key HKEY_Local_Machine\Software\Classes\htmlfile\shell\open\command.
So just download this file, unzip it and double click to extract the registry.
Solution 4:
• Open registry editor and search (Ctrl + F) for the value nocontrolpanel.
• Change its value from 1 to 0.
Do mention the solution that worked for you.
Thanks you!

Had spent hours changing settings and anti virus settings to get hyperlinks to work. This was important to me because I wanted to use them to link some documents to audio files.
Changed the default browser as you sggested everything now O.K. Sick of Microsoft and ie problems so won’t be changing back in the forseeable future. Many thanks for your help.

Tried loads of things but still no luck,tried your option 1 but do not have add remove programs, I am running vista basic.
Error “This operation has been cancelled due to ……..”
I have get this Error after i have uninstall “Chrome” from Google. The final solution for me was, to replace in the registery all entries ChromeHTML in to htmlfile and than the problem was solved
Solution number 2 is work for me.
Thank you for your suggest.
I reinstalled google chrome and no longer get the error. Thanks ….Have been trying to fix this for 6 hours.
The 4th Options worked for me thanks a lot.
This happened to me when I uninstalled Chrome. I changed the default web browser to Firefox and the links worked. I changed the default back to IE and the links still worked. No reinstallation of Chrome was needed nor any corrections to registry.
None of the steps above worked for me.
But check out this comment: Eddy dated March 11th, 2010 at 7:08 am
That’s what did it for me!! Thank you so much.
solution 4 worked for me thanks a lot.
nice tips, work great.. thanks for sharing
Eddy no.4 solution works like a charm!
Thank you Eddy your solution save my time and effort!
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.
WORKED THANKS !!!!!!!!! great im using XP
Uninstalled Chrome to start the problem. None of the fixes worked. Reinstalled Firefox and it fixed itself.
None worked for me. I solved mine by downloading some file called “Re-Enable Portable” here http://www.softpedia.com/get/PORTABLE-SOFTWARE/System/Re-Enable-Portable.shtml
It worked!

Hi,
I also found this problem after uninstalling Google “Chrome” (excuse me while I throw up!). I tried the “change the default web browser” idea and other ideas on this page but worked. However, this worked straight away.
