Several users have reported an issue in which web links (hyperlinks) no longer work in Outlook 2007 and Word 2007. Users experiencing this problem may receive the following error message:
“This operation has been cancelled due to restrictions if effect on this computer. Please contact your system administrator.”
This problem is generally caused by a corrupt Internet Explorer registry key. As such, the first thing you should try is resetting web settings in Internet Explorer. In Internet Exploer, click the Tools menu, click and select Internet Options. In Windows XP, go to the Programs tab, and then click the Reset button. In Windows Vista and Windows 7, click the Advanced tab then select reset. Apply the changes.
If that doesn’t work, you will need to edit the registry, following these steps, as described by Slipstick Systems:
- Start, click Run, type Regedit in the Open box, and then click OK.
- Browse to HKEY_CURRENT_USER\Software\Classes\.html
- Right click the value for the .html key and select Modify…
- Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
Repeat this process for each of the following keys:
- [HKEY_CURRENT_USER\Software\Classes\.htm]
- [HKEY_CURRENT_USER\Software\Classes\.html]
- [HKEY_CURRENT_USER\Software\Classes\.shtml]
- [HKEY_CURRENT_USER\Software\Classes\.xht]
- [HKEY_CURRENT_USER\Software\Classes\.xhtml]

Several users have reported significantly slower performance under Internet Explorer 8, particularly when the browser is first launched or when navigating to new pages. Delays of up to 30 seconds or more have been reported.
The problem, in most cases, is the presence of IE restricted sites and enhanced security configuration zones, which are generally created automatically by spyware removal software, such as Spybot and IESpyAd. Traditionally, the presence of these entries has been hugely beneficial, offering protection against malicious software. However, Internet Explorer 8 includes new security measures that may obviate the need for these entries, and the browser can suffer a tremendous speed hit in their presence.
The fastest and easiest way to remove these entries and dramatically increase Internet Explorer 8′s speed is to use the DelDomains package. Right click on this link and save the file to your desktop. Next, right-click on the downloaded file (DelDomains.inf) and select “Install.” The package will remove all Internet Explorer restricted sites, enhanced security configuration zones and trusted sites.
Alternatively, or in addition to the above fix, you can try registering actxprxy.dll, a process that has improved Internet Explorer 8′s performance for a handful of users.
Click the Start button then search for “CMD.” Right-click cmd.exe and select “Run as Administrator,” then type regsvr32 actxprxy.dll and press return. Quit then re-launch Internet Explorer 8 and check for improved performance.
