Haven't as yet tried your command line solution. Last night I re-installed W8,then tried to update again
This time ,it still didn't show any downloading in percentages,but when I went to switch off the laptop,it stated switch off & update. So I did
This lead to the laptop spending hours reversing the updates and getting stuck in a re-boot cycle
This morning ,the only way to stop this,was to use F8 and action yet another fresh install. This is still happening
Before the below, I will try the CMD line option.
I will switch off updates,and wait for a W8 Image/repair disc I bought from Ebay. The plan is to reinstall W8 from the disc,from in the current W8 environment .
I'm still trying to find the option is the BIOS to allow booting from a DVD & USB drive
It sounds to me that the trial/free software (including the security software)installed by these manufacturers might be the problem. I personally call them junk. Is this an Acer laptop we're talking about? If so restore to factory setting and do the usual. Once windows is loaded and you get to the desktop, uninstall all the junk via programs and features without opening any of the supplied software. Change how you install updates by selecting notify me but let me download and install. Reboot, and then go to Windows update and select a few at a time. Don't connect anything to a usb port while you do this, just use the thumb pad.
