CaptBilly1Eye Updated - 3 years ago There are a myriad of tweaking utilities that include options to "Clear History on Shutdown." Using Registry cleaners or tools like CCleaner will also clear the Run history. If you want to have Windows retain a history of what you type into the Run line, here is a quick Registry edit that will set that up: 1. Go to the following location in the Registry Editor (regedit): HKEY_CURRENT_USER → Software → Microsoft → Windows → CurrentVersion → Policies → Explorer. 2. On the right hand side panel look for ClearRecentDocsOnExit. 3. double click on ClearRecentDocsOnExit and type in its value as 0 and make sure Hexadecimal is selected. (removing the key ClearRecentDocsOnExit will accomplish the same thing) 4. Then just click on OK and close the Registry Editor. setting the value to 1 will cause Run History to be removed with each shutdown. If you find the key is missing, you can create it by right-clicking and selecting New > DWORD Value. Give it the name ClearRecentDocsOnExit. Be sure to spell it exactly that way. Then double click on it to edit the value to 1 to remove history or 0 to retain history. Put a dot in front of Hexadecimal and click OK I hope this helps.
