By
default, Internet Explorer 6 is preinstalled in all versions of Windows XP =
and
cannot be removed. To provide computer manufacturers more flexibility in
configuring desktop versions of Windows XP, Microsoft has made it possible =
for
OEMs, administrators, and users to remove user access to Internet Explorer
while leaving the Internet Explorer code intact and fully functional to make
sure the functionality of programs and operating system functions that rely=
on
it. For example, Windows XP supports an "IEAccess=
=3Doff"
switch in the Unattend.txt file, and Internet Explorer has been added to the
Add/Remove Windows Components section of the Add/Remove Programs tool in
Control Panel. This does not reinstall Internet Explorer.
