'This script (the core was pulled from Microsoft's website, and the 
' WindowsUpdate agent install was borrowed from Torgeir Bakken - thank 
' you!) will tell the WU agent to 'detectnow', download and install 
' missing windows updates as compared to it's update server. Works for 
' WSUS and regular Windows Update site. 
'
'This will now reboot the computer if specified after the udpates have 
' been applied (or if there is a reboot pending from a previous update session). 
'
'NOTE: If there are a LOT of downloads to pull, the status window (or log) 
' will say "Downloading" for that entire time. I'm not sure how to get 
' a download progress of each update...maybe someone can help me with that. 
'
'Note on command-line switches: If you don't specify a switch (for 
' example, 'email:') the corresponding variable defined in the script will 
' provide the needed information (command-line switches take precedence). 
'
'Why I put this script together: 
'Our desktop deployment technicians needed a script that would pull 
' updates immediately and install. 
'
'We have some computers that are sometimes logged on or not (but 
' they run services that must be running almost constantly), and are never rebooted. 
'
'The user ignores the 'you have new updates available' message, so updates are never 
' installed. This script will let you install the updates, and then it tells the 
' WUA to present the 'restart' message - which more users are apt to respond to. 
'
'If the client running the script doesn't have the 2.0 WUA installed, 
' Torgeir's portion of the script will automatically install it (please 
' contact me if this doesn't work - I modified his script slightly to plug 
' into mine!). 
'
'After the script runs, it will email a recipient the resulting logfile that is 
' produced. Very handy for running with my Front-end to PSEXEC tool. 
'
'You need to edit the following variables: 
'sExePath - this is the location of the WindowsUpdateAgent20-x86.exe. Download 
' it from http://go.microsoft.com/fwlink/?LinkId=43264 
'strMailFrom - arbitrary reply-to address 
'strMailto - email address you want the report to mail to (this is for manual mode 
' - or if the command-line switch isn't specified). 
'strSMTPServer - the IP address of the email server you are sending the reports 
' through. 
'
'Optional variables: 
'Silent - 0 = verbose, 1 = silent (no windows or visible information) 
'Intdebug - 0 = off, 1 = 1 (see some variables that are being passed) 
'strAction - prompt|install|detect. Prompt gives users opportunity to install 
' updates or not, install just installs them, detect updates the WU collection and 
' downloads the updates (but does not install them) - useful if you want to 
' have the computer refresh its stats to the stat server but not install the 
' updates. 
'blnEmail - 0 = off|1 = on. If set to 0, the script will not email a log file. If 
' you specify an email address in the command-line, this will force the script 
' to switch blnEmail to '1'. 
'strRestart - 0 = Do nothing|1 = restart|2 = shutdown. Command-switch 'restart:' 
' supercedes this variable. 
'
'Command line switches: 
'action: prompt|install|detect 
'mode: silent|verbose 
'email: you@yourdomain.com 
'restart: 0 (do nothing)| 1 (restart) | 2 (shutdown) 
'force: 0 (do not enforce restart action - this is optional, by default it is set 
' to 0) | 1 (enforce restart action) 
'SMTPServer: overrides strSMTPServer above
'emailsubject: Overrides default subject. Server name is appended to this text. Use quotes if spaces
'emailifallok: 0 (dont send email if server up to date and no reboot pending) 1 (always send email)
'fulldnsname: 0 (use server name only in subject) 1 (use full dns name in email subject)
'
'Finally, rename the file with .vbs
