Registry Hack Allows Updates For Windows XP SP2

Microsoft may have recently ditched support for its Windows XP SP2, but Finnish anti-virus software firm F-Secure has developed a hack to allow the ageing operating system to still receive security updates.

The hack can trick Windows XP SP2 in to believing its SP3 by tweaking a particular Registry key.

The trick can be used to install the patch for the critical LNK shortcut vulnerability (KB2286198) on Windows XP SP2. The same method was used to run the Grand Theft Auto IV PC game on Windows XP SP2.

The company explained in a blog post that, by editing the registry key ‘HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Windows', changing the DWORD value CSDVersion from 200 to 300 and restarting the system, the computer wil think it is running XP SP3.

F-Secure has warned that “this update is NOT officially tested or supported by Microsoft for SP2. And we do NOT recommend that anybody use this tweak in a production network of any kind.”

The company said that there is considerable amount of risk in editing the registry key.

Is it worth taking the shot? If you have installed the LNK update on your SP2? Let us know below.
