I installed 3 updates, which after rebooting resulted in a reboot loop, never going past the "configuring your computer for windows" stage.
Last known good configuration, safe mode etc make no difference (as expected). I have no system restore images available.
I used dism to uninstall one of the updates, but the other two appear to be MSP patches, and so I cannot use dism to uninstall them.
From what I have been reading it appears I must use wusa, however wusa does not seem to be included in WinRE.
Does anyone have a suggestion of how I can access wusa to uninstall these updates, and hopefully reverse this problem?
