The operation of deleting a parameter or registry key can be performed using the reg.exe utility supplied with the Microsoft Windows operating system and does not require the involvement of additional third-party software.
Instructions
Step 1
Click the Start button to bring up the main system menu and enter cmd in the search box to launch the Command Prompt tool.
Step 2
Call the context menu of the found object by clicking the right mouse button and select the "Run as administrator" command to meet the security requirements of Microsoft.
Step 3
Enter the value reg /? in the command line field to view the parameters of the reg.exe utility.
Step 4
Use the value of the reg delete key_name command to delete the entire selected key with subkeys and parameters. Example:
reg delete HKEY_CURRENT_USER / Software / WindowsFAQ deletes the entire WindowsFAQ section with all entries and subkeys.
Step 5
Select the reg delete key_name / v entry_name command to delete the selected entry in the partition. The absence of the specified registry entry implies the deletion of all entries and parameters of the specified key. Example:
reg delete HKEY_CURRENT_USER / Software / WindowsFAQ / Tedt / v Path deletes the entries for the Path parameter.
Step 6
Use reg delete key_name / v / ve to delete entries with missing parameter values.
Step 7
Enter the value of the reg delete key_name / v / va command to delete all entries in the specified key while preserving the subkeys of the selected key.
Step 8
Note that executing the command to delete an entry, value, or registry key must be confirmed by the user each time, and use the value reg delete key_name / f to cancel the confirmation prompt.
