HowTo: Perform an In-Place Upgrade on Windows Vista, Windows 7, Windows Server 2008 & Windows Server 2008 R2 October 7, 2011


An in-place upgrade is the final alternative before you have to reinstall the operating system.
Note: It takes the same amount of time to do the upgrade as to reinstall the operating system. Also, some of your customized Windows settings may be lost through this process.

Performing a repair installation will restore the current Windows installation to the version of the installation DVD. This also requires the installation of all updates that are not included on the installation DVD.

Note: Performing a repair installation will not damage files and applications that are currently installed on your computer.

To perform a repair installation of Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2, follow these steps:

  1. Close all the running applications.
  2. Insert the Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2 DVD in the computer’s DVD drive.
  3. In the Setup window, click Install Now.

    Note: If Windows does not automatically detect the DVD, follow these steps:

    1. Click Start, and then type Drive:\setup.exe in the Start Search box.
      Note: The Drive placeholder is the drive letter of the computer’s DVD drive.
    2. In the Programs list, click Setup.exe.
    3. In the Setup window, click Install Now.
  4. Click Go online to obtain the latest updates for installation (recommended).
  5. Type the CD key if you are prompted to do this.
  6. Select the operating system in “Install Windows” page you want to Upgrade or Inplace.
  7. Click Yes to accept the Microsoft Software License Terms.
  8. On the Which type of installation do you want? screen, click Upgrade.
  9. When the installation is complete, restart your computer.

QuickTip: File on a Windows 2008 or Vista system is owned by trusted installer and can’t be replaced or modified

In Windows 2008 Server or Windows Vista, Various Files are by default owned by the ‘Trusted Installer’ account. The administrator may have read only access to these files.At various times, you may be instructed by Microsoft Support to replace versions of these protected files.
In addition, various configuration files are owned by the Trusted installer and you may need to make modification to these files to enable tracing or make other configuration changes. If you manually take ownership of the files, you will not be able to restore the default configuration since the GUI doesn’t display the account ‘trusted installer’ in the owner dialog. It is highly recommended that after making the needed changes, you restore the ACLs to their previous default configuration. The proper procedure for this is to first backup the ACLs using icacls and then later restore the ACLs back on the file(s) once the operation is complete.
These ACL’s can be backed up by typing the following command at the command prompt (use an elevated command prompt if UAC is enabled by right clicking a cmd.exe shortcut and choosing ‘run as administrator’)

icacls %windir%\system32\CustomApp.exe /save C:\BackedUpACLs.txt

After this you should take ownership of the file and modify the permissions. This will allow you to replace the file (after making a copy of it first) or make the needed modifications.

When you are finished making your changes and are ready to return the permissions to the default, you can use the following command to restore the ACLs that you previously backed up. This will allow Trusted Installer to become the owner of the file again.

icacls c:\windows\system32\ /restore c:\BackedUpACLs.txt

This file is text based and can be viewed with the following command:
notepad c:\MyBackedUpACLs.txt

Note: You may use wildcards, but keep in mind that it’ll fail if you haven’t taken ownership of all of the files that match your wildcard mask and changed the permissions to grant yourself control. In other words, if you back all of the executables in System32 with the following command:

icacls %windir%\system32\*.exe /save c:\BackedUpACLs.txt

Then, you would have to take ownership of ALL of the .exe files which ‘trusted installer’ owned and change thier permissions to grant your logged in account rights to the file. This is because the restore operation will attempt to restore ALL of the .exe’s that matched your wildcard mask. If it finds a file that it cannot access, the entire opreation will stop and the files that normally would have worked will never be reached.
