An administrator can make use of the Windows logons counter for the following:

  • To look at a history of previous users who logged on to a particular Windows workstation in order to access information -- whether legally or illegally.

  • If a workstation has Internet access available, the administrator can use the logons counter history to determine the last user who accessed the workstation, in case of any warning of unauthorized Internet activity.

For a workstation that is dedicated to one user, the logons counter cache can be set to 5 since there will not be multiple users trying to access this workstation.

For a workstation that is located in a public area and requires various users logging in to the network, that value can be set to a higher number, 12, for example.

To set the number of past logons the network administrator will need to perform Registry editing. It is advisable to backup the Registry before performing the following steps:

  • Start the Registry Editor

  • Select HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon

  • Click on Edit select New | String Value

  • Enter CachedLogonsCount and press Enter

  • Double click on the new value and set this value to any number based on the information supplied above

  • where 0 being the lowest 50 being the highest.

  • Then click OK

Exit from the registry Editor and reboot the machine.
