I really don't understand what your are trying to do. do you want to add a new windows computer object to the database, or add an existing windows computer object to the list of related items on a work item? 
if you are trying to create a windows computer by hand, i would recommend against it. there are much easier ways to get that data from SCCM or AD via connectors. maybe you could elaborate on your need?
If you are trying to relate an existing windows computer to a work item, then your script is correct. you just need to get the computer object in one hand, the work item in the other and mash them together with a New-SCSMRelationship around the correct Relationship
class. remember that About (System.WorkItemAboutConfigItem) is for the Affected config item, where as Relates (System.WorkItemRelatesToConfigItem) is for the related config items. an arrow affects the target and is related to the archer; don't get them confused.
the only other interpretation (and the one i find least likely) is that you are trying to relate two computers together, in which case the script is still correct, except, obviously, the relationship class should be System.ConfigItemRelatesToConfigItem,
and you would need to get a windows computer in each hand.
