Free ebook: Introducing Windows 8.1 for IT Professionals
Microsoft released an update yesterday for the Disk cleanup utility. The problem Windows keeps copies of installed updates from Windows Update, even after installing newer version of updates. So the older versions of updates that are no longer needed and taking up space.
In Windows XP era the uninstalls were just hidden folders under Windows directory so easy to clean. Since Windows Vista this is now stored in the Windows Services folder WinSXS.
The space used by WinSXS can grow significant. In the past you could remove Service Pack uninstall files which helped, but Service Packs are not so common anymore. I think Windows 7 will never see SP2, yet the updates keep filling the WinSXS folder every month.
After the update is installed (no reboot needed) and you run Diskcleanup:
and when you click “Clean up system files”
You’ll see new options:
This update of diskcleanup delivers a new option Windows Update cleanup which deletes older versions of updates that are no longer needed and just taking up space.
The update is available through Windows Update as important or direct download at KB article posted below:
Now unfortunately this update is not available for Windows Server 2008 R2, while there are plenty scenarios where cleaning up WinSXS folder is helpful there too!
This update extends the Key Management Service (KMS) for Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, and Windows Server 2012 to enable the enterprise licensing of Windows 8.1 and Windows Server 2012 R2.
KMS provides support for the following KMS client activations:
KMS uses a KMS host key to activate itself on a KMS host and to establish a local activation service in your environment. This update extends support for KMS to provide activation for Windows 8.1 and for Windows Server 2012 R2.

Microsoft published an important hotfix for .NET 4.5 earlier this year. It wasn’t picked up on by many, therefor a quick write up on the matter.
Since Exchange 2013 is built on top of .NET 4.5, it is recommended to install the hotfix on all Exchange 2013 Mailbox and Multi-Role servers. The hotfix will reduce the memory consumption of the store worker processes.
If you’re using Windows Server 2008 R2, the hotfix is KB2803754 and can be requested here; when using Windows Server 2012 the hotfix is KB2803755 which can be requested here.
After installing the hotfix, you need to do one of the following things:
I’d prefer the first option. Note that you need to restart the server for the change to become effective.
