Windows Update Error 0x800f0922

Hi Rob,

Error 0x800f0922 occurs when downloading the newest update of Windows 10. It also means that you have less than 500 MB in system reserved partition. You may follow the methods provided below and check if you'll be able to update your device.

Method 1. Check your Internet connection

You need to make sure that you have an internet connection and if possible, you are using wired connections

Method 2. Check .NET Framework

Make sure you have the latest version of NET Framework installed. You may enable it in Windows features. Here's how:

1. Type Windows Features on the search bar and press Enter.
2. Select Turn Windows Features on or off.
3. Check any boxes related to DotNet Framework and save selection.
4. Restart your PC.

Method 3. Turn off your Firewall

We know that this is strange doing, but even Firewall can prevent updates occasionally. Here's how you can turn it off:

1. Type Firewall on the search bar and press Enter.
2. Open Turn Windows Firewall on or off.
3. Turn off Firewall for both private and public networks.
4. Save your selection.
5. After saving your selection, you may try updating your device.

Neither of these helped. The update still fails.

I'm doing a hardware refresh in April on my HEDT. Hopefully the new copy of Windows 10 Home will have this update already installed on the disk. I just have to live with the constant nag messages to restart my system and the fail/rollback issue until then.

Thank you for posting back and we're sorry for the delay.

1. The system reserve and recovery partition are two different things. The former is created during Windows installation and has a fixed drive space of 500mb in Windows 10. It contains the Boot Manager, Boot Configuration Data (both responsible for booting Windows 10), and the startup files used for BitLocker Drive Encryption. While the latter is created by the user or device manufacturer for recovery purposes in case of a serious system error. It usually contains the device drivers, software, and manuals.
2. Should you need more drive space for your recovery partition, by all means, you can increase it if you still have unallocated drive space left or by shrinking other drive partitions.
3. We apologize for the confusion, we're referring to .NET.

Get back to us if you need further assistance.

 OK so WHICH partition needs to be larger. The OEM Recovery or the Reserve ? Any suggestions on how to accomplish this task ? Thanks

 OK so if the newest Windows 10 KB4487017 (OS Build 17134.590) for the last 2 days. Error code of 0x800f0922. So frustrated. Microsoft insists on forcing you to use this and now they just leave you hanging and expect us to fix what is clearly YOUR error. How frustrating do you think this is  to the consumer? Ready to go to MAC and you folks are making a great case for this to happen. NO help, no one cares, no one responds. So how should we treat you folks ?

 I have changed NOTHING and been updating for 2.5 years now and then this build just will not  complete ! FRUSTRATED to the MAX !  not update (after 2.5 years WHICH partition needs to be enlarged and by how much ? The Reserve or the Recovery ? Why is this happening after 2 plus years ? I can tell you that this is so very frustrating Microsoft.

Hello Mr. Justine,

        As suggested above, I have tried all the above options, but not able to update Windows.

       I opened the Windows Features and did not find Dotnet file, but I did find .NET Framework and >NET framework 4.7(Advanced) files and checked them. After completion of the process, I got a message:-

      "Windows could not complete the required changes. Windows requires a reboot to return to original position"

      I tried it twice and everytime, I got the above message though I also turned the Firewall(Public and Private Firewall).

     The problem remains unchanged though the update is being downloaded automatically and subsequently reversed.

    Now I have got the new message" Your device is missing important security and quality fixes."

Perhaps it is for the above update.

Having the same issues when I try to update Win 10 Home 64 Bit. Been fine for 2.5 years and now it is doing this "Unable to complete the updates undoing the recent updates. Very frustrating indeed .

same issue here for ages now disabled updates for 35 days hopping a cumulative update would work,same issue update fails roles back the update and trys again the next day...pretty annoying.

 Same issue here. Agreed It is very frustrating how MS just leaves you hanging out to dry when you have done nothing wrong. Grrrr.
