Sharepoint failed installation

My issue:

ISSUE #3: when running Setup.exe for Microsoft SharePoint Server 2010 you may experience the error:

Setup is unable to proceed due to the following error(s):

A system restart from a previous installation or update is pending. Restart your computer and run setup to continue.

For the list of pre-requisites needed to install the product please refer to:

Correct the issue(s) listed above and re-run setup.

Check the value of the following Registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\UpdateExeVolatile – if the value of the UpdateExeVolatile Registry key is anything other than 0 you will see this message.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations – if the PendingFileRenameOperations Registry key has any value you will see this message.

To remove an orphaned UpdateExeVolatile registry key value

1.Open a registry editor, such as Regedit.exe or Regedt32.exe.

2.Navigate to HKLM\SOFTWARE\Microsoft\Updates\

3.In the right navigation pane, double-click the UpdateExeVolatile key.

4.Configure the key with a value of 0

5.Close Registry Editor.

To delete the orphaned PendingFileRenameOperations registry key

1.Open a registry editor, such as Regedit.exe or Regedt32.exe.

2.Navigate to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\

3.In the right navigation pane, right-click the PendingFileRenameOperations key and select Delete.

4.Close Registry Editor.

*UPDATE* 3/29/2011
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOptions”
can ALSO be a culprit..
