  1. I tried your every update from last 2 months but all failed…It said “this update not support by your windows etc etc”…I have windows 10 64bit…and tried every 64bit you uploaded….all failed.

    • Hello Prasoon,
      All the latest updates are for windows 10 Version 1511. Please check the version of your windows 10 OS. Press Win + R and then write winver.exe command there and press enter. There are chances that you may have to upgrade your Operating system first. You can also download latest version of windows 10 ISO and do a clean install. But before doing so do take backup of you data first.

  2. Thanks forposting the fillesize of the x64 bit update. Microsoft has either not mentioned the size or made it difficult to find.

  3. Hi prasoon!
    I faced the same problem.
    Go to All Settings->Update & Security->Advanced options-> “untick” the Defer upgrades
    Without untick that “Defer upgrades” option, you couldn’t install the offline updates.

  4. Basically I installed this update yet the Security Update for Adobe Flash remains in Windows Update and waited days yet can’t download and install.

    Can tell me what I’ve done wrong or Windows Update screwed up again?



  5. Please update with latest cumulative updates: KB3140768 and KB3140745.

    Thank you for your fantastic effort.

  6. Great project. Is it possible to update the content and to publish links to the latest cumulative updates for Windows 10 (May-June 2016 update)?
