ListUpdates.ps1

#
# Description: List Windows Update from computers in array and export to file.
#              We used it for troubleshooting a strange problem which lead us to
#              believe it could be a common windows update for the affected computers.
#
# Usage:       1) Enter hostnames in $hosts array
#              2) Change wanted timeline date in the Where-Object { } clause
#              3) Run script
#
# Note:        - Requires local administrator access on remote computer (i.e. domain admin)
#              - Threads aren't implemented so it currently queries the computers one by one.
