Recommended hotfixes for Windows 2012 R2 and HyperV clusters

[Rumple]

Anyone found any other links for recommended hotfixes. Seems like after June 2017, Microsoft yet again just stops updating the articles...unless of course there have been no hotfixes at all since June (highly unlikely, but you never know)

Microsoft moved to a cumulative update model so as long as you are installing the Monthly Quality Update rollup, you should be covered

These are the only hotfixes that I've deployed that I haven't confirmed are included in the monthly quality update rollups . The easiest way to check if you need any particular hotfix is to compare the build number of the files in the KB article with the build number on the files installed on your servers.

Hi Rumple,

I agree with nmdange here. Since Microsoft switched to CU updates on a monthly basis this is changed. I recommend also to install the latest update on your systems. I am aware that there have been some (serious) issues with those and I'm pretty sure it will happen again, but depending on your size of organization, you might postpone those updates for 1 or 2 weeks and monitor potential issues before testing.

Last but not least, my preferred method for testing is starting a backup in a virtual lab, try out the CU and see if it doesn't cause any issues before installing it on production

Cheers
Mike

I do install the rollup patches, I just wasn't sure if they were including these in these monthly patches or not. Typically they would have security and "updates" but hotfixes were basically released as they found issues but were not regression tested...I guess now, we all do the regression testing for them...

Mark,

The regression testing actually happens when they release it but it is a manual update. After that, it becomes automated. But you are more or less right

The whole "Recommended hotfixes" thing came out of Microsoft's broken support model for Windows 7/Server 2008 R2.

The original support model was to release hotfixes for individual issues, test them more fully, and then release a service pack. After SP1, Microsoft decided to stop releasing service packs for Windows 7/Server 2008 R2, but they kept making hotfixes. Since those hotfixes were never going to get into a service pack, the "Recommended hotfixes" pages started popping up so that customers that needed them could be made aware of them.

I'm super glad that Microsoft fixed this and went to the cumulative update model. Having to try to hunt down hotfixes was very time consuming. I've got over 400 hotfixes in my Server 2008 R2 archive that I had to individually review and evaluate (not to mention track down and download).
