Fix: PDF Files will not open in Internet Explorer 10 | 11

PDF Files will not open in Internet Explorer

1. Press Windows Key + R combination, type put Regedt32.exe in Run dialog box and hit Enter to open the Registry Editor.

2. Navigate to the following location:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main

3. In the right pane of this location, look for the TabProcGrowth namedDWORD. This DWORD actually is short from of Tab Process Growth; which sets the rate at which IE creates New Tab processes. If you’ll find theDWORD there, it must having the Value data as 0. If you don’t find it there, create it manually using Right click -> New -> DWORD Value. Now click on the same DWORD to modify its Value data:

4. Now set the Value data from 0 to 1. Click OK. Putting Value data 1 ensures that all tabs for a given frame process run in a single tab process for a given mandatory integrity level (MIC) level. You may now close the Registry editor and reboot to see the results.

Hope you find the fix useful!
