The User Agent String can be changed by modifying the following Registry Entries, or creating them if they do not already exist.
Index: | 0x2B |
Keys: | HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\User Agent |
Value: | Version |
Type: | REG_SZ |
As you can see I made Internet Explorer look like Firefox in the screenshot below. It's worth noting however that this will likely need to be done to the SEUM-USER-X user accounts for the "HKEY_CURRENT_USER" or you can apply it to all users of the system under the "HKEY_LOCAL_MACHINE" key.
