I have a tablet that run Windows 8.1 RT. I did a restore few days ago then I started do the updates availables in Windows Update. After a few Update/Reboot cycles, KB 2919355 April 2014 Update 1 was installed and now Windows Update keep searching for update forever. I've tried everything I found on the net to fix this (Windows Update Troubleshooter, stop the service / delete c:\Windows\SoftwareDistribution folder, etc.) but I can get this fixed.

I found two similar posts for Windows 8.1 with accepted answer that suggest to install KB3102812:

  1. Cannot install any updates on clean Windows 8.1
  2. https://answers.microsoft.com/en-us/windows/forum/windows8_1-update/windows-81-windows-update-stuck-at-checking-for/c0d42129-7479-44cb-a150-a95ad707ab2b

However, the tablet run Windows RT and KB3102812 page (https://support.microsoft.com/en-us/kb/3102812) state that :

The update for Windows RT 8.1 can be got only from Windows Update.

The update is also not available on the Windows Update Catalog for ARM architecture.

Does anyone has a suggestion to fix this Windows Update issue or any hint where I could go to download the KB3102812 for RT?

EDIT

I now know from Microsoft Support that installing KB3138615 should fix the issue but I still can't find a link to manually download this update for ARM devices.

You can download the update kb3138615, which includes the latest Windows Update Agent, from this link. Also stop Windows Update service like in Windows 7 to avoid the hang at "Searching for updates on this computer" while trying to install the MSU.

Can you please describe step by step, how did you install the kb3138615? When I try to install the downloaded msu file, it creates a new folder in C:, which contains the following files:

Windows8.1-KB3138615-arm.cab

Windows8.1-KB3138615-arm.xml

Windows8.1-KB3138615-arm-pkgProperties.txt

WSUSSCAN.cab

and then the installation hangs at "Searching for updates on this computer". I do not understand the linked article how to avoid that.

I found some advice, how to install an update cab files so I restarted the tablet, then I launched Command Promt as an administrator and used the follovig command:

dism /online /add-package /packagepath:"C:\foldername\Windows8.1-KB3138615-arm.cab"

It seems the update KB3138615 is installed.

Then I had to restart the tablet, run the Windows update troubleshooting tool and after another restart the Windows Update service started to work.

So it is OK now, but I am not sure about my installation method of the kb3138615. There is also the WSUSSCAN.cab in the folder and I didn't install it. Is it OK?

In any case I would like to know, how to install the KB3138615 msu file next time better way and avoid the hang at "Searching for updates on this computer".
