To resolve this issue:
1. Create a parallel installation of Windows NT.For additional information how to do so, click the article number below to view the article in the Microsoft Knowledge Base:
259003 (http://support.microsoft.com/kb/259003/EN-US/) How and Why to Perform a Parallel Installation of Windows NT 4.0
2. Start your computer to the parallel installation of Windows NT, and then start Registry Editor.
3. On the Window menu, click HKEY_LOCAL_MACHINE on Local Machine.
4. On the Registry menu, click Load Hive.
5. Type the path to the System hive of the prior installation, typically %systemroot%\system32\config\system, and then click Open.
6. When you are prompted for the name of the key, type TEST, and then view the following registry entry:
HKEY_LOCAL_MACHINE\TEST\Select
7. Note the setting for the Current DWord value in the preceding registry key. This is typically 0x1, and is represented as CURRENT:Reg_Dword:0x1. This value indicates that the "CurrentControlSet" for your original Windows NT installation corresponds to ControlSet001 in this window. A value of 2 would indicate that the "CurrentControlSet" for your original Windows NT installation would correspond to ControlSet002, and so on.
8. Locate the following registry key
HKEY_LOCAL_MACHINE\TEST\ControlSetXXX\Control\Sess ion Manager
where XXX is the CurrentControlSet that you identified in the preceding step.
9. Under the Session Manager key, note and then delete any PendingFileRenameOperations entries.
10. Click the TEST hive, and then click Unload Hive on the Registry menu.
11. On the Registry menu, click Load Hive.
12. Type the path to the Software hive of the prior installation, typically %systemroot%\system32\config\Software, and then click Open.
13. When you are prompted for the name of the key, type TEST2.
14. Remove any PendingFileRenameOperations entries in the following registry keys:
HKEY_LOCAL_MACHINE\TEST2\Microsoft\Windows\Current Version\RunOnce

HKEY_LOCAL_MACHINE\TEST2\Microsoft\Windows\Current Version\RunOnceEx
15. Click the TEST2 hive, and then click Unload Hive on the Registry menu.
16. Quit Registry Editor, and then restart your original installation.
