Sometimes after uninstalling software, you may end up with blank entries in the System Configuration Utility (MSConfig.exe) in Windows XP. This happens if the startup entry is present in the registry with blank value data. This article tells you how to remove those orphaned entries by editing the registry.
Removing Blank Startup Items from MSConfig
1. First, enable the item if it’s already disabled, and then click Apply. This moves back the entry to the "Run" registry key, which you can edit manually.
2. Note down where the blank entry is located in the registry, by expanding and viewing the Location column. (Hint: HKLM represents HKEY_LOCAL_MACHINE registry branch, and HKCU means HKEY_CURRENT_USER)
3. Click Start, Run. Type Regedit.exe and press ENTER.
4. Navigate to the registry branch that you noted in Step 2.
5. Right-click on the value which has blank data, and choose Delete.
Additional Note: If the (Default) or unnamed value has blank data, you’ll have to delete that as well. Right-click on the (Default) and choose Delete. It should now read as (value not set)
Editor’s Note: MSConfig in Windows Vista and Windows 7 no longer displays the "blank" entries. See this screenshot.
