WifiHistoryView is a simple tool for Windows 10/8/7/Vista that displays the history of connections to wireless networks on your computer.

BSSID of the router/Access Point, and more...
WifiHistoryView can read the wifi history information from a running system or from external event log file of another computer.
Ths utility works on any version of Windows, starting from Windows Vista and up to Windows 10. Both 32-bit and 64-bit systems are supported.
Previous versions of Windows (Windows XP and earlier) are not supported.
Source of Information
WifiHistoryView loads the Wifi history information from the 'Microsoft-Windows-WLAN-AutoConfig/Operational' event log of Windows. This even log is usually stored in the following file:
- Version 1.45:
- WifiHistoryView now reads archive log files when connecting a remote computer.
- Added 'Read archive log files' option in 'Advanced Options' window (You can turn it off if you don't want to read archive files).
- Added option to read the log files from shadow copy (Requires to run WifiHistoryView as administrator).
In shadow copies you might find older log records that don't exist in your current log files.
- Fixed bug: 'Copy Selected Items' worked improperly when setting the 'Unicode/Ascii Save Mode' to 'Always UTF-8'.
- Version 1.40:

- Version 1.36:
- Added option to set the AutoBackup/Retention mode of the wifi history log file (In 'Event Log Options' window - F8).

By default, old events are deleted when the event log is full)

- WifiHistoryView now reads archive log files ( Archive-Microsoft-Windows-WLAN-AutoConfig%4Operational*.evtx ).
Be aware that archive log files are created only if the configuration of Microsoft-Windows-WLAN-AutoConfig/Operational log is 'Archive the log when full'.
Also, in order to read the archive files, you have to run WifiHistoryView as administrator.

and modify the maximum size of the log file. This feature requires elevation.
