better than pressing keys... script it like this in powershell
while(1) { # Loop forever
sleep -Seconds 300 # Wait 5 minutes
$wshell = New-Object -ComObject wscript.shell
if($wshell.AppActivate('Chrome')) { # Switch to Chrome
Sleep 1 # Wait for Chrome to "activate"
$wshell.SendKeys('{F5}') # Send F5 (Refresh)
} else { break; } # Chrome not open, exit the loop
}
