 * Fix Windows 7 Installation When it Freezes **

When you try to upgrade your PC system from Windows Vista to Windows 7 you may find that the install process hangs at 62% and nothing else happens. This problem occurs because the Iphlpsvc service stops responding during the upgrade process. If this happens to you, you can cure the problem as follows:


 * 1) Remove the Windows 7 installation DVD from your drive then restart your computer. Your PC will revert back to Windows Vista.
 * 2) Click **Start**, right-click **Computer**, and then click **Properties**.
 * 3) Click **Advanced System Settings**, then click **Environment Variables**.
 * 4) Under System variables, click **New**.
 * 5) Type **MIG_UPGRADE_IGNORE_PLUGINS** in the Variable name field.
 * 6) Type **IphlpsvcMigPlugin.dll** in the Variable value field.
 * 7) Click **OK** > **OK** > **OK** to close the open dialogues.
 * 8) Start the upgrade installation again. This time it won’t hang at 62%.
