Last written time of a registry key can be determined using several ways.
Determining the "Last Write Time" of a registry key?
Whenever you modify a registry value manually or programmatically, Windows keeps track of the last written time for that particular key/branch. This article will tell you how to determine the Last Write Time of a registry key.
Using the Registry Editor
- Click Start, Run and type Regedit.exe
- Navigate to the key for which you want to determine the last write time
- From the File menu, click Export.
- In the Save As type drop-down box, select Text Files (*.txt)
- Type a file name and press Enter
- Open the text file using Notepad, and look at the Last Write Time value.
Sample text
Key Name: HKEY_USERS\.DEFAULT\Control Panel\Desktop
Class Name: <NO CLASS>
Last Write Time: 3/5/2006 - 11:45 AM
Value 0
Name: ActiveWndTrkTimeout
Type: REG_DWORD
Data: 0x0
Value 1
Name: AutoEndTasks
Type: REG_SZ
Data: 0
Note:
- Windows 95/98/ME systems do no maintain the Last Write time.
- Third-party programs use the RegQueryInfoKey API call to retrieve the Last Write Time.
