Usually scammers look in the Control Panel to see which software is installed. It is very suspicious if all the software has the same installation date or has a very fresh date. To change the installation date follow the next steps:

• hold <Windowskey> + <R>
• type regedit and hit <ENTER>
• locate HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
• in the left pane click on the key (most times the program name)
• in the right pane double click on InstallDate
• change the date (format 11112233  -> 1=year, 2=month, 3=day)
• if there is no InstallDate you can create it by yourself:
  • right click in the right pane on empty space
  • choose New > String Value
  • call it InstallDate
  • double click on the new string called InstallDate
  • enter the date in the format as shown above
