Had .1474 program version since installing clean W8-64 Pro on Oct. 26 and these BSOD's, mostly when logging back in after a screen lock or return from hibernation. Certainly networking seemed unstable, needing to frequently disconnect the WIFI and reconnect to get the web going again, loosing shared resources on the WLAN. After applying the patch following the instructions, system stable and dozen locks, log-in, hibernates and things remain running. The Intertubes operate spiffy again.
