You only need to use the Extend option on the Recovery Partition. It will automatically resize the partition you're taking space from. Just make sure you select the correct partition to grab space from, in the pull down menu (most likely C:).

Used the tool to increase my partition by 1GB. Spat it's dummy 1st time, but another restart and the update worked successfully.

Good job. 👍

Brian you're a legend man! Long time subscriber here. I booted my old win 10 gaming PC and I got that error. I remembered you posted a vid about an update and came here for help. You never disappoint!

[oldfrenchie]

Win 10 Pro user. Followed the MiniTool method. Once done, rebooted and attempted to install the KB503441. It failed (error 0x80070643). Rebooted a second time, tried the update again, it sat at "0%" for a minute, disappeared, checked list of installed updates and son of a gun, there it was, successfully installed. Merci Beaucoup Brian.

[JeaneGenie]

That was so simple and easy to follow. MS should recruit you as their chief engineer.

Followed your instruction using MiniTool....and it worked perfactly...expept with the operation where we hane to ''extend '' the partition once it is created didn't have the ''window RE minitool '' option to right clic on....i had to right clic on the ''unallocated space '' in the lil square, bottom right of the minitool window then choose in the menu to extend partion....mayby it has to do with the fact that my OS is win10 pro....anyway....thanks for this i can update window no problem...

[algercomalekmalki]

For the operation with the Mini Tool it worked because you had the recovery partition and the unallocated partition adjacent . I tried the operation when the two partitions were not adjacent the Mini Tool refused to do the job . I didn’t dare to do it the Microsoft way because of the ‘adjacent ‘ stuff . In you example you had the two partitions adjacent so every thing worked fine.

Hello sir Brian. I followed every instruction of this video and it worked flawlessly. Thanks for your help and here's my like, subscription and all my respects for you. Greetings from Tehuacan, Puebla, Mexico. God bless you so much.

Hi there...I have a question please...My recovery partition, there is no name on it and i did the second way so now i have 4GB of space on that partition. All was good on Minitool software...But it didnt worked out. Still the same update error. On my disk management the recovery partition is in the first place and not at the end like you. And there is no name, is blank. But it was the only partition that was 500 and something megabytes and also was wroten on the Minitool as a recover partition. What can i do? Thank you

[drsysop]

Do not mess with the partitions as it's a Microsoft issue. I made a new install of 10 & same error. It is not necessary to get update & they will have a fix for it soon, Just ignore it!

[ludwigboyadjian]

Thank you very much Brian. It's seems that the mini tool is much easier to use over what is suggested by MS. But personally we should not fix their error. I would rather wait for the patch. Maybe MS want us to break our computer in order to buy a newer one.

[sansy]

Hmmm, I don't quite understand. My recovery partition is 1.61 GB and 100% free (as shown in Disk Management). Why do I still encounter this error, while the update only requires 250MB?

[keyonno]

On my system the Recovery Partition is the very 1st partition with the EFI Partition 2nd then my OS is the 3rd partition. When I did a clean install of Windows 10 it just defaults to that configuration.
Has anyone else seem that difference in their partition layout?

[wbgudpk]

Worked slick to fix the Microsoft Windows 10 break. My computer had 2 primary partitions, so the 1st way was too risky. The 2nd method was safer and it fixed the error.

[gpcrawford]

I’m confused when you use minipartition you refer to partition tool that you created surely this would be called recovery if you haven’t used Microsoft’s workaround or am I missing something.

[dariopoloniato]

Sorry, Britec09! But do it manually like that it is a huge risk to lose all you data in hard disk.
It is highly recommended to do a backup of the entire C: before start this procedure!

[Lubmachine]

Bit confused sorry. I gathered that the instructions were 2 parts.. first part the hard way and the second part the easy way using the tool. I skipped forward to the Mini tool part and did everything in that part but then it said that you needed to use command prompt before hand to make the bit that says ""Windows RE Tools partition".. so now im scared to do anything in case i stuff it all up lol SO do you need to do every single part mentioned in the video from the start?

[christopherdecker]

It worked! You will be using Disk Management and the Minitool Partition Editor if your Windows 10 partition is encrypted by Bitlocker, like my laptop's is 😉. Just wanted to let you guys know!

[BassLife]

For the first method, what should I do if everything seems right, but when it try reagent /enable it says “REAGENTC.EXE: The Windows RE image was not found.”? my Windows 10 works just fine, which means the steps should be right. I know because I have two desktops, both with Windows 10 Pro, and the first one it worked just fine. Any help would be much appreciated

[KeronBullock]

Great video! I have already applied the commands to my pc as well. It's pretty straight forward once you know what to do however I will not recommend anyone who isn't comfortable modifying partitions to do this and just wait for them to fix it themselves. I hope Microsoft never repeats this mistake again by telling everyone to modify partitions. I hope they will update the Installation media for currently supported versions of Windows to enforce the change.
