Windows Update Error 0x80070643

For some time now, our systems have been encountering the error 0x80070643 with update KB5034441. After extensive searching online, I have found a solution.

Important! There’s a risk of causing damage, so I recommend either creating a data backup beforehand or having an experienced admin handle the matter.

What’s the problem? It seems that Microsoft creates a Recovery Partition during the Windows installation. This partition allows you to restore Windows to a certain state. For certain versions, this partition is quite small, and that’s where our update comes into play. This update wants to update the content on this partition, but unfortunately, there isn’t enough space, resulting in an error.

The following steps will help ensure that this update runs smoothly:

  1. Press the Windows key and type diskmgmt.msc
  2. Right-click on the entry and select “Run as administrator”
  3. You should now see a list of all the drives on your computer, and on the one where Windows is installed, there should be a partition marked as a recovery partition with about 500 MB at the end (see images).
  4. Right-click on the partition before this 500 MB partition and select “Shrink Volume”; we need to make room for the recovery partition.
  5. The dialog box may take a while to open; enter 500 under “Enter the amount of space to shrink in MB” and click “Shrink”.
  6. Shrinking will take a while, and afterward, there should be unallocated space between the two partitions.
  7. We now need to extend the last partition into this free space. To do this, we download an additional tool, AOMEI Partition Assistant Standard. Any other partitioning tool will work as well (such as Diskpart, which is included with Windows).
  8. Install and then start this tool.
  9. In AOMEI Partition Assistant Standard, select the last partition and click on “Resize Partition”.
  10. Drag the slider to the left and add the 500 MB to the partition.
  11. Confirm with OK and then click “Apply” at the top to adjust the partition size.
  12. Restart the computer.
  13. Run Windows Update.
  14. Be happy!

I hope this helps someone out there. If there are any questions, just comment.

Should i buy the new Prusa MK4 3D-Printer?

About three years ago, I bought my first Prusa MK3S, second-hand. Unfortunately, there were a few delivery issues, and the part was quite bent, making it quite a challenge to start printing initially. After some service work (replacing guides and spindles, tensioning the Y-belt), however, the printing experience was as smooth as everyone claims it to be with Prusa printers.

This year, Prusa surprised us with the MK4, and in my opinion, it brings some upgrades over the MK3S that are truly worth considering an upgrade to this new version.

So, I did it! I sold off the old printer quite decently on willhaben.at and purchased a new one. My engineer’s heart demanded the kit version, as that’s the best way to learn how the thing functions and how it’s built.

Three days ago, the printer arrived, and I could hardly wait to start assembling it. And what can I say? It was better than claimed everywhere:

  • The instructions provided via the Prusa Wiki are perfect, and practically anyone can assemble the printer with them.
  • All necessary tools and aids are included in the kit, so no extra tools are needed.
  • The division of components into individual bags, the labeling of these bags, and the level of detail in the instructions -> Perfect!
  • Prusa even developed an app that assesses belt tension using the microphone (you vibrate the fully assembled belt, and the sound helps determine whether it’s too tight or too loose). I understand that this is feasible and not exactly rocket science, but still a cool feature!
  • They even include a bag of gummy bears 🥰.

You really need to take about two days to get everything together, but it’s a delight. In short, after two days of assembly and subsequent test printing, there were ZERO problems.

By now, I’m already on the tenth consecutive print, without ever encountering an issue or problem. I definetly recommend the upgrade to the new MK4 and opting for the kit version (which is also about €250 cheaper); it pays off, and the assembly is enjoyable!

Merry Christmas and a Happy New Year,

Yours sincerely, Seesle

PS: This is not a paid advertisement or anything; I myself pondered for a long time about upgrading from the MK3S (after hours of watching YouTube influencers).
