How to block Flash animation in websites?
Flash provides a great way to make your web page interactive with graphical illustrations etc. On the other hand, visiting flash sites occupy your internet bandwidth more. If you're using a dial-up connection and wish to block Flash intro's in websites, you can disable Flash animations by setting a Kill-bit for this ActiveX control:
{D27CDB6E-AE6D-11CF-96B8-444553540000}
Shockwave Flash Object
C:\WINDOWS\system32\macromed\flash\flash.ocx
NOTE: Backup the Registry before modifying it. See this article for more information on backing up the registry keys.
*
Open Registry Editor by typing REGEDIT.EXE in the Start, Run dialog.
*
Navigate to the following location:
[HKLM\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility]
*
Create a sub-key named {D27CDB6E-AE6D-11CF-96B8-444553540000}
*
In the right-pane, create a new REG_DWORD value named Compatibility Flags
*
Set the data for Compatibility Flags to 400 (hexadecimal)
To undo the change, merge the REG file which you've created. Or, simply delete the {D27CDB6E-AE6D-11CF-96B8-444553540000} sub-key under ActiveX Compatibility key.
