HOWTO enforce WindowsXP security

There are dozens of reasons to abandon Windows XP (security, technical, …), but if you have no option, at least you can mitigate them by enabling the PosReady option and install all MS published security updates.

Open Registry Editor and go to:

HKLM\System\WPA\PosReady

the add/edit the value ‘Install‘ as DWORD and set it to 1.

Reboot, and run Windows Update by the following command line:

wuauclt /updatenow

It should find more than hundrends of items to install.

 

PS: From April 2019, even MS Security Essentials didn’t update its definitions anymore.
