Uninstalling Windows Updates / Disable Automatic Updates / Performing a System Restore (Windows 7)


Microsoft incorporates an update service (Windows Updates) that allows for periodically updating Windows and other Microsoft applications. Unfortunately, updating/maintaining Windows through the use of the update service often exposes significant risk of "breaking what's not broken", often leaving users "dead in the water" so to speak.


If you are suddenly experiencing system and/or application instabilities, a likely culprit may be a recently installed Windows Update!


One such recent Windows Update that may seriously effect our valued CompuHost users is labeled as...


"Update for Windows 7 for X64-based Systems (KB2505438)".


This update, by Microsofts' own admission (see below), potentially breaks any application that incorporates advanced "DirectWrite" technologies such as those utilized extensively within CompuHost and thousands of other high performance, multi-tasking applications.


Known Issue (quoted directly from support.microsoft.com/kb/2505438)
"Important: After you install KB2505438, applications that render text by using DirectWrite may encounter errors, including application crashes. This is because the hotfix package does not contain an updated version of another driver. The hotfix package that is described in KB2454826 contains the updated version of this driver."


Unfortunately the above example is just one of many, and most likely will not be the last. For this reason, we STRONGLY encourage users, especially those that depend on their computer for a living, to DISABLE Automatic Windows Updates and instead perform updates manually as needed. You may find instructions on disabling Automatic Updates below.


Disabling Automatic Windows Updates

  1. Open Windows Update by clicking the Start button Picture of the Start button, clicking All Programs, and then clicking Windows Update.

  2. In the left pane, click Change settings.

  3. From the drop-down selections, select "Download updates but let me choose whether to install them."

  4. Click OK. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Uninstalling Windows Updates

If a potentially errant update, suspected of causing instabilities, crashes etc., has already been installed on your system, you may uninstall the applicable update(s) by following the steps below. Alternately, you may wish to simply perform a "System Restore" back to a date preceding the first occurrences of instability, thus uninstalling all potentially errant updates installed since the selected date. (See instructions further down the page.) 

  1. Open Installed Updates by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Programs, and then, under Programs and Features, clicking View installed updates.

  2. Click the update that you want to remove, and then click Uninstall. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

If you want, you can reinstall the update later by going to Windows Update in Control Panel and checking again for updates.

Performing a "System Restore" back to a date preceding the first symptoms of instabilities.

  1. Navigate to the Start -> All Programs -> Accessories -> System Tools program group.

  2. Click on the System Restore program icon.

  3. Click Next > on the Restore system files and settings window.

  4. Choose the restore point that you want to use.


    Note: Check the Show more restore points checkbox to see more than the most recent restore points.


    Note: Any restore points that you created, scheduled restore points that Windows 7 created, and those created automatically during the installation of certain programs will be listed here. You can not use System Restore to undo Windows 7 changes to a date that a restore point does not exist.


  5. Click Next >.

  6. Click Finish on the Confirm your restore point window to begin the System Restore.


    Note: Windows 7 will shut down to complete the System Restore so be sure to save any work you might have open in other programs before continuing.


    Important: System Restore will not revert any of your non-system files like documents, email, music, etc. to a previous state. These types files are completely unaffected by System Restore.


  7. Click Yes to the Once started, System Restore cannot be interrupted. Do you want to continue? dialog box.

  8. System Restore will now restore Windows 7 to the state that was recorded in the restore point you chose in Step 4.


    Note: The System Restore process could take several minutes as you see the "Please wait while your Windows files and settings are being restored" message. Your computer will then reboot as normal when complete.


  9. Immediately after logging in to Windows 7 after the reboot, you should see a message that System Restore completed successfully.

  10. Click Close.

  11. Check to see if whatever Windows 7 problem you were troubleshooting has been corrected by this System Restore.

    If the problem still persists, you can repeat the steps above and choose another restore point if one is available.

    If this restoration caused a problem, you can always undo this particular System Restore.
