Important information about Windows 10 and ACBLscore

Recently the Windows 10 Anniversary Update was released. It is very important that you
do NOT install this update. The Windows 10 Anniversary Update breaks the function keys (F1, F2, etc.) and requires a manual work around for them to work again.

Click the box below for instructions on how to Block the Windows 10 Anniversary Update. This will not stop Windows 10 from applying security updates and standard patches. This only blocks large incremental updates.


Note: A previous version of ACBLscore® is not needed to install.
