To block IE7, navigate to the following subkey (or folder) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Setup\7.0 then create a new DWORD value DoNotAllowIE70 and assign it a value of [...]]]> Here’s a quick and simple additions for you SysAdmins out there, how to block Windows XP from automatically downloading Internet Explorer 7 and IE 8. This is a simple addition to the Windows Registry

To block IE7, navigate to the following subkey (or folder)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Setup\7.0
then create a new DWORD value
DoNotAllowIE70
and assign it a value of 1

The procedure for IE8 is almost identical for IE8, just change the version number,
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Setup\8.0
then create a new DWORD value
DoNotAllowIE80
and assign it a value of 1

If you’d like to create a registry file, then just create a new text file with a .reg extension, for example IE7and8Blocker.reg once that’s created, just copy and paste the following into the registry/text file:

1
2
3
4
5
6
7

Windows Registry Editor Version 5.00
 
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Setup\7.0]
"DoNotAllowIE70"=dword:00000001
 
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Setup\8.0]
"DoNotAllowIE80"=dword:00000001

Lastly, if you don’t want to follow my examples, you can download a prepackaged Toolkit available from Microsoft for IE7 and IE8.
