I am about to rebuild my X201 Laptop with Windows 7 Ultimate x64. I downloaded systemupdate40-2009-10-19.exe and systemupdate40-2009-10-19.txt. The txt file is extremely poorly formatted for notepad. It is one long line.
Also, from what I can make out in the description at the begining of the file it only has support for XP, 2000 and Vista:
"ThinkVantage System Updatefor Microsoft Windows XP, Windows 2000, and Windows Vista"
