I just upgraded my laptop to Windows 8 Pro for about a week. 

This laptop is used so far for web browsing only. No additional program installed. So pretty much standard windows.

But today when I login using ordinary user account I get the following message

Windows couldn't connect to the windows all-user install agent service. Please consult your system administrator.

This is quite weird as it is a standard windows with no change ever made, none any program installed.

The product supposed to have 90 days support from Microsoft. But it is very hard to find how to contact Microsoft regarding this, and I can only find this forum.

    Hi Jon,

    Please follow the methods to fix the Windows 8 update issue:

    Method 1: Scan for Malware:

    Microsoft Safety Scanner

    http://www.microsoft.com/security/scanner/en-us/default.aspx

    Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.

    Method 2: Run SFC / Scannow. Please follow the below steps:

    a. Type Windows key +W

    b. Command Prompt (Admin)

    c. Type cmd

    d. At the Command Prompt, type: sfc/scannow

    The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

    Method 3: Run the Checksur Commands:

    My new laptop came with windows 8 and I received the same message.  Also it has failed to install several of the recent updates.  I hate using my admin account, which is what I am using now, because of the potential security risks.  How can I ensure that the updates install properly?

    Hi Sandeep,

    Thanks for your time replying this. I was able to login using Administrator account (fortunately I enabled it when I still used Win 7).

    I tried created new user but still get the same error.

    After several reboot, I the system run automatic update and suddenly the problem disappear by itself.

    So I think the update solve this.

    Thanks again,

    Agus
