RegScanner is a small utility that allows you to scan the Registry, find the desired Registry values that match to the specified search criteria, and display them in one list. After finding the Registry values, you can easily jump to the right value in RegEdit, simply by double-clicking the desired Registry item. You can also export the found Registry values into a .reg file that can be used in RegEdit.

Advantages over RegEdit find of Windows

  • RegScanner utility display the entire search result at once, so you don't have to press F3 in order to find the next value.
  • In addition to the standard string search (Like in RegEdit), RegScanner can also find Registry values by data length, value type (REG_SZ, REG_DWORD, and so on), and by modified date of the key.
  • RegScanner can find a unicode string located inside a binary value.
  • RegScanner allows you to make a case sensitive search.
  • While scanning the Registry, RegScanner display the current scanned Registry key, as opposed to RegEdit, that simply display a boring "Searching the registry" dialog-box.

System Requirements

This utility works in any version of Windows, from Windows XP to Windows 11. A separated download for x64 systems is also available.

Using RegScanner

RegScanner is a standalone executable, and it doesn't require any installation process or additional DLLs. In order to start using it, just run the executbale file - regscanner.exe

After running RegScanner, you should select the desired scan/search options, and click OK to start the scan.

Delete Selected Keys/Values

The delete feature was added in version 1.80 after many requests from RegScanner users. This feature allows you to easily delete unwanted Registry keys and values that you found in the search process. However, in order to decrease the chance of damage from accidental delete action, this feature works as follows:
  • Before any delete action, RegScanner will ask you if you want to delete, and the default answer is No.
  • When you delete a value item, only the value is deleted, when you delete a key, the entire key is deleted.
  • A key won't be deleted if it has one or more subkeys.
  • For every delete, the delete values/keys are added into a .bak file located in the folder of RegScanner.exe
    If RegScanner fails to create the .bak file, it won't delete the selected items.

Tips for using RegScanner

  • If you want to view all Registry values under a specific key, choose 'Registry item contains any value' in the matching combo-box, uncheck the 'Scan the following base keys', and in the Base Key combo-box type the desired key (For example: HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer)
  • If you want to view all Registry values that contains large amount of data, uncheck the 'Add entry for each found key' option, choose 'Registry item contains any value' in the matching combo-box, choose the 'Display only data with the following lenth range', and type the data length range that you want to find, for example: from 1000 bytes to 100000 bytes.
  • If you want to view the list of all Registry keys that have been modified in the last few hours or days, check the 'Add entry for each found key' and 'Add only keys' options, choose 'Registry item contains any value' in the matching combo-box, choose the 'Display only keys that their modified time is within the following range' option, and then select the modified date/time range that you want to view.

Searching DWORD/Binary values

Starting from version 1.40, you can search DWORD/Binary values. In order to specify a DWORD value to search, you can type (In the Find string text-box) a decimal value (for example: 255) or an hexadecimal value (for example: 0xff).
In order to specify a binary value that you want to search, type (In the Find string text-box) a sequence of hexadecimal bytes, with or without spaces between them.
For example:
01 3f c7 a1 27 cc 4a

Searching the Registry in a remote computer

Starting from version 1.40, you can search the Registry in a remote computer on your network. In order to do that, you should login to the remote computer with admin user. Also, be aware that searching the Registry in a remote computer might be quite slow.

For more information about connecting to the Registry of a remote computer, read this:
How to connect a remote Windows 7/Vista/XP computer with NirSoft utilities.

Using reg: Links

Starting from version v1.50, RegScanner allows you to use reg: URL as a link to the Registry key in RegEdit editor.
For Example: Clicking the link below will open RegEdit with the specified Registry key:
You can also type the same reg: string in the address bar of Internet Explorer or in the Run dialog-box of Windows.

In order to enable/disable this feature, go to the File menu of RegScanner utility, and choose the 'Support Reg: Links' option.
Be aware that changing this option only affects the current logged on user.

Using the /regedit and /clipregedit Command-Line Options

Starting from version 1.50, you can use RegScanner.exe utility to open the desired key in RegEdit, by using the /regedit command-line option.
For example:
RegScanner.exe /regedit "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion"
Starting from version 1.60, you can also use the /clipregedit command-line option if you want to open a key that you copied into the clipboard.

Notice about transition effects

If you want that RegEdit will be opened as fast as possible with the right Registry value, you should disable the 'transition effects' on your system. (On Windows 2000, go to the 'Display Properties' window, select the 'Effects' tab, and uncheck the 'Use transition effects...' option.
