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.
This utility works in any version of Windows, from Windows 98 to Windows 10.
A separated download for x64 systems is also available.

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.

a key that you copied into the clipboard.
Notice about transition effects
