256986 Description of the Microsoft Windows Registry



SUMMARY
When you choose to perform an in-place upgrade over an existing Windows NT installation, Windows NT Text-mode Setup adds or modifies some or all of following Windows NT Registry values:
 * HKEY_LOCAL_MACHINE\SYSTEM\Setup

RestartSetup:REG_DWORD:0x1

SystemSetupInProgress:REG_DWORD:0x1

UpgradeInProgress:REG_DWORD:0x1

SetupType:REG_DWORD:0x0
 * HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager

BootExecute:REG_MULTI_SZ: autocheck autochk* sprestrt

When you restart the computer, you automatically enter GUI-mode Setup.



MORE INFORMATION
If it is desirable to back out of the in place upgrade, you will need to modify the Windows NT registry to reset the values back to the default or replace the SYSTEM hive from a current emergency repair disk:

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" online Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" online Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

%SystemRoot%\System32\Config\System

 * 2) After you are back in the original Windows NT installation, you will need to re-enable any disabled devices and services the upgrade process turned off.
 * 3) Run Regedit (Windows 95 registry editor) and select the following key:


 * 1) From the Edit menu, select Find, and then type OldStart in the Find What box.
