    What about non-enterprise users?  Why is a 90-hotfix rollup not available to a few "bazillion" Windows 7 users whose systems exist outside of any enterprise??  For me, this "gem" is still hidden.  Unless Microsoft plans to tank Windows 7 much sooner than advertised, a W7 service packs would seem to be a much better solution.

  2. Hello df

    Thanks for the feedback. I'm passing it on to colleagues in the Windows support teams.  

    It is slightly unusual to see the word "enterprise" in the KB title however as far as I know anyone can download and install the fix. I think it is just an indication of to whom the issues addressed are most likely to be relevant to.

    This rollup is what is called a GDR release (see…/824684 for descriptions of the different release types and channels.)  

    Our support lifecycle for Windows 7 can be found here:…/lifecycle . Currently it is listed as in support until January 2020.

    Hope that helps

    The fixes in MSKB 2775511 primarily target scenarios found on domain-joined clients and servers which is why the package was  made available on the Windows Catalog site as opposed to the more transitional Windows Update site. MSKB 2775511 may be freely installed on home and non-enterprise users and may well experience boot, logon and post logon performance improvements.

  4. We've got some new wording added to the KB article now as well that hopefully clarifies this point.
