How to Disable Restarting GUI Mode Setup

• Microsoft Windows NT Server versions 3.51, 4.0
• Microsoft BackOffice Small Business Server versions 4.0, 4.0a
• Microsoft Windows NT Workstation versions 3.51, 4.0

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

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.

1. Install a parallel copy of Windows NT to a different folder on your local hard disk.



2. Run Regedt32.exe from the newly installed version of Windows NT and go to the following key:
   
   HKEY_LOCAL_MACHINE



3. Click Load Hive on the Registry menu and open the following registry file on the original Windows NT installation:
   
   %SystemRoot%\System32\Config\System
   
   Assign it a name other than System (such as Test).



4. Go to the following registry key and note the value for Current:REG_DWORD (this selects which ControlSet00x to load when booting and is the one that needs modification):
   
   HKEY_LOCAL_MACHINE\TEST\Select



5. Go to the following registry key
   
   HKEY_LOCAL_MACHINE\TEST\ControlSet00x\Control\Session Manager
   
   where x is the value of Current:REG_DWORD



6. Double-click the following entry:
   
   BootExecute:REG_MULTI_SZ: autocheck autochk* sprestrt
   
   Remove the entry sprestrt from the multi-string editor box, and then click OK.



7. Go to the following registry key:
   
   HEY_LOCAL_MACHINE\test\Setup



8. Reset all of the following Registry entries to have a value of 0x0:
   
   RestartSetup:REG_DWORD:0x0
   SystemSetupInProgress:REG_DWORD:0x0
   UpgradeInProgress:REG_DWORD:0x0
   SetupType:REG_DWORD:0x0



9. After you have made the necessary changes, go to the following registry key and then click Unload Hive on the Registry menu:
   
   HKEY_LOCAL_MACHINE\TEST



10. Exit Registry Editor, exit the parallel version of Windows NT, and then restart the original version of Windows NT. The Setup program should NOT restart.



11. 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.



12. Run Regedit (Windows 95 registry editor) and select the following key:
    
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services



13. From the Edit menu, select Find, and then type OldStart in the Find What box.



14. For every disabled device or service, change the Start value to equal the OldStart value, pressing F3 to find the next value until all devices and services are set back to default values.



15. Exit Regedit and restart the computer. You should be back to an operational system
