Windows Update fix for corruption errors like 0x80070002

Posted by essjae on February 21, 2014

Microsoft KB 947821 (http://support.microsoft.com/kb/947821)

If you’ve gotten one of those cryptic 0x800xxxxxx Windows Update errors, Microsoft finally has a fix for Vista and higher, no XP solution.

Fix Windows Update corruption errors such as 0x80070002 and 0x80070057

Windows Update corruption errors prevent Windows updates and service packs from installing. For example, an update might not install if a system file is damaged. If the error you see is in the following list, try the solution in this article.

0x80070002 | 0x8007000D | 0x800F081F | 0x80073712 | 0x800736CC | 0x800705B9 | 0x80070246 | 0x8007370D | 0x8007370B | 0x8007370A | 0x80070057 | 0x800B0100 | 0x80092003 | 0x800B0101 | 0x8007371B | 0x80070490

 

Windows 8.x and Server 2012 Rx

To resolve this problem, use the inbox Deployment Image Servicing and Management (DISM) tool. Then, install the Windows update or service pack again.

  1. Open an elevated command prompt. To do this, swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search. Type Command Prompt in the Search box, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
  2. Type the following commands. Press Enter after each command.
    Note It may take several minutes for each command operation to be completed.

    • DISM.exe /Online /Cleanup-image /Scanhealth
    • DISM.exe /Online /Cleanup-image /Restorehealth
  3. Close the command prompt, and then run Windows Update again.

DISM creates a log file (%windir%/Logs/CBS/CBS.log) that captures any issues that the tool found or fixed. %windir% is the folder in which Windows is installed. For example, the %windir% folder is C:\Windows.

Why does Windows 8 Hyper-V require SLAT?

Posted by essjae on February 6, 2013

Since Windows 8 is designed as a desktop/workstation or client OS, the requirement for SLAT makes a lot of sense for most users.

The lack of SLAT (Intel EPT and AMD RVI) was a big issue when using Hyper-V and a Windows 2008 (r1 and r2) system equipped with a high-end video card as a workstation (as opposed to a server).  When 2008r2 became able to use SLAT, the video performance issues were just resolved.

VPC Guy Ben A has an excellent selection of blog posts on SLAT and Hyper-V.

Issue: Video performance may decrease when a Windows Server 2008 or Windows Server 2008 R2 based computer has the Hyper-V role enabled and an accelerated display adapter installed

Removing the status bar and standard buttons tool bar from the Remote Desktops MMC

Posted by essjae on May 14, 2012

Two things that have always bugged me with the Remote Desktops Administrative Snap-in was that there were no options on the menu to customize the view, specifically, the status bar and standard buttons toolbar. 

I’ve googled around trying to find a fix, then it dim 20W bulb went off in my head.  Look at a standard MMC console and make one how I want it and copy the config to the TSMMC file.

It was pretty simple.  The key line from the tsmmc.msc is:

<ViewOptions ViewMode="Report" ScopePaneVisible="true" NoStatusBar="true" NoStdButtons="true" DescriptionBarVisible="false" DefaultColumn0Width="200" DefaultColumn1Width="0"/>
    </View>

By adding NoStatusBar=”true” and NoStdButtons=”true” I was able to get more remote desktop “desktop”.

On my secondary monitor, my TS screen is now 1768×1000 vs. 1768×953.  Not a big deal on a 1920×1080 monitor, but 47 pixels on smaller screens makes a big difference.

The New Efficiency

Posted by essjae on October 20, 2009

I have to say that I’m pretty excited about Windows 2008 R2, Hyper-V R2, and Exchange 2010 after hearing and seeing them today at “The New Efficiency” conference put on by Microsoft.

I’m also excited to start delving into V-Pro by Intel for my company’s notebook computers!  Remote support from the hardware level!
