A simple way to apply hotfixes to a whole bunch of servers

I was recently challenged with how to apply a whole lot of hotfixes to a bunch of servers so I came up with this solution using PSexec from Sysinternals that can be downloaded here http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx

First I need to download and extract all of the hotfixes I need to install

2012 Clustering http://support.microsoft.com/kb/2784261

2012 Hyper-v http://social.technet.microsoft.com/wiki/contents/articles/15576.hyper-v-update-list-for-windows-server-2012.aspx

I had some challenges with getting WUSA to execute remotely so I needed to get the Hotfixes locally on each host. To accomplish this a simple batch file that makes a directory called "hotfix" on the root of C:\ for each host in my text file "ALL_hosts_Cluster_Nodes.txt"

for /f %%a in (ALL_hosts_Cluster_Nodes.txt) do mkdir c:\hotfix
for /f %%a in (ALL_hosts_Cluster_Nodes.txt) do xcopy /d/y \\srourceserver\c$\scripts\Hotfixes\*.msu /i \\%%a\c$\hotfix\

That was pretty quick and easy. Now I have all the Server 2012 hotfixes for hyper-v and clustering locally on each server.  

Next I created another batch file using the same server list. Save the contents below to install.bat.

psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2785638-v2-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2795531-v2-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2795997-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2796000-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2806542-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2823643-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2823956-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2825135-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2832478-v2-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2834026-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2836402-v2-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2838043-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2838669-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2840681-x64.msu /passive /quiet /norestart
psexec -s @ALL_hosts_Cluster_Nodes.txt wusa c:\hotfix\Windows8-RT-KB2848344-x64.msu /passive /quiet /norestart

Then just execute install.bat file and bam.

Success! = output of  wusa exited on rrvmash26 with error code 3010.

Don't forget to restart your servers after applying the updates.

 Thanks!
