is there way modify script can following:

1. prompt me enter computer name
2. display uptime of said computer entered

this script says need insert line computer names want for, me, info.

i think understand instead of parameter reading computer list should remove , use calculated properties param?

no, calculated property output. here's quick example:

$computerlist = read-host 'enter computer name'  foreach ($computer in $computerlist) {      get-wmiobject win32_operatingsystem -computername $computer |         select @{n='computername';e={$computer}},                @{n='lastbootuptime';e={[system.management.managementdatetimeconverter]::todatetime($_.lastbootuptime)}},                @{n='uptime';e={(get-date) - ([system.management.managementdatetimeconverter]::todatetime($_.lastbootuptime))}} }
