Common Windows 10 Upgrade Errors

Microsoft has rolled out Windows 10 on July 29, and ever since then millions of people from around the world have made the upgrade to the software giant’s latest (and perhaps last) operating system.

Inevitably, however, a release on such a massive scale can’t go through without a hitch, so many people have reported a variety of errors and bugs while going through this process – despite Microsoft’s best efforts to smoothen things out.

None of these problems are insurmountable, however, and the following post will guide you through dealing with them.

How to fix error message 80240020

Although Windows 10 wasn’t intended for everybody all at once (instead the release was supposed to be a gradual one), many people found a way around this and attempted to force the free upgrade on their computers.

However, after Windows Update is done downloading the necessary files, many of these users encountered the error 82040020 message.

Note that this isn’t actually a problem and there’s nothing wrong with the installation file – you just have to be patient until Windows 10 is ready to install. If you don’t want to wait, there is something you can do to immediately install Windows 10, which is to modify a registry key.

Here is how to do that, but be advised: modifying registries can have all sorts of nasty consequences if you don’t know what you’re doing, so proceed with caution!

First of all, find the registry key Locate the registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade]

(If this key doesn’t exist, you will have to create it.)

Now, create a new DWORD (32-bit) Value with Name = AllowOSUpgrade, and set the Value = 0x00000001.

After you’ve modified the registry, go back to the Control Panel and check for new updates. The process should now work just fine.

How to fix error message 0x80200056

If you got an error code 0x80200056, all it means is that the upgrade was interrupted by the computer rebooting or the user account signing out. To fix the issue, simply restart the process, and make sure whatever interruption there was in the first place doesn’t happen again.

How to fix error message 0x800F022

If there isn’t enough space on the System Reserved partition, you will get the error 0x800F022 message. To get around this, you will need to use a third-party software which increases the size of the System Reserved partition.

You can also get the same error if your system can’t connect to the Windows Update servers, so make sure Windows Update is enabled and you aren’t connected to a network using a VPN.

How to fix error message 0x800F0923

This particular error likely means that there’s a problem with a driver or another piece of software, which isn’t compatible with the Windows 10 upgrade. To see what went wrong, open the Get Windows 10 app, click Check your PC, and identify the software that’s having compatibility issues.

After identifying the problem, go to the manufacturer’s support website and download the latest drivers or software update. If you can’t find any, uninstall the software you are having trouble with.

How to resolve failure to upgrade to Windows 10

While upgrading your operating system, you might also encounter error messages like “Error: We couldn’t complete the updates. Undoing changes. Don’t turn off your computer.” or “Error: Failure configuring Windows Updates. Reverting changes.”

It could be difficult to figure out exactly what the issue is from such a vague message, so you’ll have to take a look at the exact error details to know more.

To find that information, go to Control Panel, then to All Control Panel Items\Windows Update\Windows update history. Once there, double-click the update with the “Failed” status to find additional details.

Once you have that, either look for the official Microsoft support instructions, or ask for help somewhere else on the internet.

How to fix compatibility issues

The error codes 0xC1900200 – 0x20008 and 0xC1900202 – 0x20008 tell you that your computer doesn’t meet the minimum requirements needed to download and install Windows 10.

You should also know that error code 0xC1900208 – 0x4000C means a particular app on your PC is preventing the update process. The easiest way to deal with this is to uninstall the software and proceed with the update.

How to make room for the upgrade

Error messages 0x80070070 – 0x50011, 0x80070070 – 0x50012, and 0x80070070 – 0x60000 tell you that there isn’t enough disk space for the update to be completed. The way to solve issues like this one is pretty straightforward (you’ve probably done this before on other occasions): make more room!

You can perform a Disk Cleanup via the tool offered by Windows, or you can simply select some files and delete them or move to an external drive.

How to update Windows to avoid errors during the upgrade

If you get an error telling you “The update isn’t applicable to your computer,” it means you’re not running the required version of the operating system which allows the upgrade to take place. Windows 7 should have Service Pack 1, while Windows 8 should be running the Windows 8.1 version.

By the way, if you’re not sure which Windows version you have installed, go to Run, type Winver, and hit Enter to find out.

How to fix Windows 10 activation issues

Some users have reported getting the message “Windows not activated” after performing a clean install of Windows 10.

First of all, you should know that Microsoft recommends updating their operating system via the “Get Windows 10” app. If you prefer to do it “manually,” by downloading the installation files yourself, here’s what you need to know:

First of all, you’ll need to upgrade your current version of the OS using Windows Update (which involves converting your Windows 7 or Windows 8.1 product key to a product key that will activate Windows 10).

Only then you should download the installation files from Microsoft and go through with the process.

You can also activate Windows 10 by phone: open the Settings app, go to Update and security, and select Activation. If your system can’t activate, you will see the Activate by phone option.

A few recommendations before upgrading

As always when performing a task on such a “scale,” it’s a good idea to back up your important files first. You can use either an external drive or a cloud service like Dropbox or Google Drive. This way, if something goes terribly wrong during the upgrade process, the consequences won’t be as severe as if you’d lost files you really needed.

Write your Windows product key on a piece of paper. If you lose it, you might end up having to purchase a new license for Windows 10, so you definitely want to take the time to do this!

Disable or uninstall security software, like antivirus programs and firewalls. Also, disconnect all the peripherals that are connected to your PC.

Finally, make sure you have a good, stable internet connection, as well as a reliable power source.
