Power Management Driver for Windows 7 has been removed from Downloads and Software

The power management driver for Windows 7 is no longer listed for the L460/T460/P50 etc. as a download option. Revision 01 of the document n1zku15w.txt (1.67.13.12) lists Windows7 as supported whereas revision 02 of the document no longer includes Windows 7. Why has this driver been removed leaving the customer with nothing to download on models that were sold with Windows 7 installed on them?
