Acer Iconia W510 Windows 8.1 Reinstall

September 8, 2019 at 1:59 pm (computers) (, , , , )

Not quite sure why I’m persevering with this one, but it is quite a nice machine!  But as I mentioned last time, it is full and has stopped updating.  So time has come to re-install and conventional wisdom on the Internet seems to think that I won’t get anywhere putting Windows 10 on it, so Windows 8.1 re-install it is.

First problem though – I’d forgotten the admin password – doh! (actually I’m sure I wrote it down somewhere and made a Win 8.1 install disk – but I seem to have lost them both!).  Thankfully a local user account is still functioning and it would appear that from a local user account you can still invoke the start-up options to refresh (i.e. re-install) the computer.  So I did.  Which is good as it is almost impossible to invoke the rescue options any other way.

Pre-requisites:

  • Windows 8.1 32-bit (English) Installation Media – get it from here: https://www.microsoft.com/en-us/software-download/windows8ISO
  • USB DVD Drive (I burnt the ISO to a disk).
  • USB keyboard, mouse and ethernet adaptor (you’ll see why in a moment).
  • Micro USB connected (in my case via an adaptor) USB hub for the above.

On reinstallation of Windows from the ISO it doesn’t recognise the dock, touch screen or Wifi so I have to use a USB hub via the tablet’s built-in micro-usb port to connect up a keyboard, mouse and USB ethernet adaptor to get online.

There is a driver package on the Asus website that covers everything: https://www.acer.com/ac/en/ID/content/support-product/4549

It is quite scary to run though as you get a very DOS looking type update programme running on restart and I’m pretty sure it is updating the UEFI BIOS somehow.  Still, once installed and restarted it was all running fine again.

But I instantly hit the same problem with Windows Updates as when I first got the machine, which I documented here.  Basically there is a problem with the Windows Update programme, and to fix it Microsoft helpfully suggest installing KB3102812 using, you guess it, Windows Update!

On examining the files already installed it looks like the Win 8.1 ISO has all the right files to have included the prerequisites for installing KB3102812 – I checked the version numbers of a few.  It also seems to list under “update history” the April 2014 cumulative update, so I simply downloaded and installed KB3102812 myself by hand as detailed in my previous blog post.  Of course, what would have been immeasurably more useful would be for the ISO to include at least up to the point of the fixed Windows Update!  Oh well.

  1. Download of the update for KB3102812.  The 32-bit download is here: https://www.microsoft.com/en-us/download/confirmation.aspx?id=49546
  2. Open a command prompt as Administrator then extract and install:
cd \Users\me\Downloads
mkdir temp
expand -f:* “Windows8.1-KB3102812-x86.msu” temp
cd temp
start /w Pkgmgr /ip /m:Windows8.1-KB3102812-x86.cab

At this stage nothing seems to happen for a while, then you get a message box saying Pkgmgr is deprecated, but do you want to restart now? On restart you get the standard Reconfiguring Windows Update type messages and then Windows starts.

At this point we can run Windows updates normally. In my case several times to get everything up to date again.

The final step was to create a system image of the new, clean Windows 8.1 machine.  But the option to do that is quite hidden, but still there somewhere.  Basically it is hidden away under FileHistory – but not the Windows 8 PC Settings File History – you have to go to the original Control Panel -> File History, then there is an option at the bottom of the left hand panel for System Image Backup.
