PowerShell – Cleaning folders containing temporary files

At the companies I’ve worked for , disk space on the system disk ran out on a regular basis for some systems and caused a lot of monitor calls. These kind of boring repetitive tasks are always the ones you want to automate.

So when I came across the great blog post “Weekend Scripter: Use PowerShell to Clean Out Temp Folders” on the “Hey, Scripting Guy! Blog”, I wanted to post it on my own blog as well. The blog post also describes the process of creating the script very well, which is very convenient for those who are relatively new to PowerShell to scripting and want to learn how to do it better.

If you want to take it even a step further, you could automate it even more. By example by automatically running the clean script when an event is generated that the disk is running out of space. You can configure this using by example:

Or you could use PowerShell remoting to do it on many systems at the same time. This could come in handy by example when after WSUS patching the content in “C:\Windows\SoftwareDistribution\Download” is not deleted automatically.

Milestone of 50.000+ views reached !!! Thanks everybody.

My blog reached 50.000+ views. Thanks everybody, this really exceeded my expectation and motivates me even more to keep going. Special thanks go out to my fellow bloggers in my blogroll and to those who shared my posts on Twitter, Facebook and other social networks.

Even though my blog exists since January 2012, I really started to blog actively around August and ever since I’ve tried to keep posting on a regular basis. At the start of 2013 I even intended to blog every day. I was able to keep it up for a short while, but it was just too time consuming. Now I try to blog something at least once every 5 days. The blog post count is now at 170.

Personally I think Microsoft is on the right track. I’m really looking forward to all new Microsoft product (preview) releases including Windows 8.1, Windows Server 2012 R2 and System Center 2012 R2 and you can expect some blog posts about this in the near future.

Event – Free Microsoft IT Camps

On a regular basis Microsoft and its partners host Free IT Camps. In the past I’ve blogged about them because I really think they’re a good way to quickly get up-to-date on products and technologies. Besides that it’s also a good way to get to know other people.

On the Microsoft Events website you can see which future events are available and not just IT Camps events.

Also should you not be able to attend an IT Camp, for Server 2012 you can also use IT Camps On-Demand.

SCOM2012 – Extract English Only MSP Update Rollup 3 files from CAB using PowerShell (and my vision on updating using WSUS/Microsoft Update)

I created this script to automate extracting English only MSP files from CAB files in the SCOM 2012 Update Rollup 3 (UR3) files. By default it will delete extracted non-English versions. With some minor modifications it can be used for any CAB file though, not just SCOM 2012 Update Rollup 3. It includes a lot of comments, so it is manageable and can be used for getting to know PowerShell better.

SCOM 2012 Update Rollup 3 can be downloaded here : http://catalog.update.microsoft.com/v7/site/search.aspx?q=2750631

The issue with SCOM 2012 Update Rollup 3 is that after downloading you’ll end up with a total of 41 CAB files. The large number of files is because they are for different components and in multiple languages. And what is even worse, is that the file names do not show which file is for which language.This script will extract all cab files to a subfolder and will then removes the non English ones. Below are some of the example files in Update Rollup 3 to give you an idea about the nondescriptive file names:

  • all-kb2750631-amd64-console_1af57997fba722cdd3dfe4b2ddb4b8d8d829dd6f.cab
  • all-kb2750631-amd64-console_3d61c9e090622b2b59ee8bf7b13b922e815bdf15.cab
  • all-kb2750631-amd64-console_494a77ddaa09206f8f61ecdfb2edfcd1e82a497c.cab
  • all-kb2750631-amd64-console_69bb307dbd450cfd8b732c2ac3845c9870bdc6d0.cab
  • all-kb2750631-amd64-console_71c65fc2ded6769edbf610958780b5a8ac374f8c.cab

Deploying SCOM 2012 components and updates to them can be done in multiple ways:                 http://technet.microsoft.com/en-us/library/hh551142.aspx

Most of the work while updating will probably be updating the agents. Basically for SCOM 2012 there are 2 major ways to install agents:

  1. Push installation (initiated from SCOM 2012). Updates can then also be deployed from within SCOM (Remotely Manageable = Yes). Push installation is often preferred, because it is easy and also allows you to push updates to clients from within SCOM 2012. The downside however is that it also requires a lot of open ports (including RPC) which might not always be acceptable:                    http://support.microsoft.com/kb/2566152. Push install and update install can also consume a lot of bandwidth and depending on your architecture (b.e. WAN links), the push install might not be the best way.
  2. A manual installation (anything that is not a push installation). Updates cannot be deployed from within SCOM (Remotely Manageable = No). Manual installation includes running setup manually, using a GPO software install or using deployment tools like System Center Configuration Manager). Using the GUI, you cannot simply set an agent back to remotely manageable = Yes. You can change this in SQL though, but keep in mind that connectivity  requirements still need to be met.

With Update Rollup 3, it is now possible to leverage WSUS / Microsoft Update to deploy updates (not the inital agent) to all SCOM 2012 components. I predict this will probably become the preferred way of updating SCOM 2012 for most companies:
+ It does not require many ports on your firewall to be opened.
+ Better bandwidth management (local WSUS, BranchCache, BITS).
+ Auto detects components on systems (component updates are not forgotten).
+ Still in control of when which updates are deployed/approved.
+ Leverage existing patch/update management procedures and systems WSUS/SCCM (standardization).
– Initial agent installation cannot be performed using WSUS.
