Following on from my post last night about the Windows Updates check on MonitoringExchange a colleague reminded me that we acutally modified the script from there as we weren’t looking for the names of updates to be listed but simply to get the total number of updates that are outstanding. The modified version of the script is listed below for reference and the source for this is at the following URL: https://www.monitoringexchange.org/inventory/Check-Plugins/Operating-Systems/Windows-NRPE/Check-Windows-Updates

As you can see from the image to the left there are a vast number of options that can be configured for a user when they login. For most of the items there are four options: Create, Delete, Update and Replace which will let you make changes to the Drive Mappings, Folders etc. The difference between Update and Replace can vary from item to item but my general understanding is that the Update will attempt to modify the existing item to match what is in the Preference whereas the Replace option will remove what is there and recreate the new object (smilar to a net use P: /DELETE /Y followed by net use P: \ServerUsers%USERNAME%)
