When you attempt to upgrade to Windows 10 from a Windows 7/8 computer using Microsoft’s Media Creation Tool, the error
0x80072F8F - 0x20000 may appear. The full error message verbatim is below:
There was a problem running this tool We're not sure what happened, but we're unable to run this tool on your PC. If you continue experiencing problems, reference the error code when contacting customer support. Error code: 0x80072F8F - 0x20000
Let’s see how to fix this error on Windows 7 and Windows 8.
Important: Information in this article (and the registry fix) is for Windows 7 SP1 and Windows 8 systems only. They don’t apply to Windows 8.1 and higher!
0x80072F8F - 0x20000 happens because the Media Creation Tool uses the TLS 1.2 Protocol, but the protocol is disabled by default on Windows 7 and Windows 8 computers. By default, only SSL3 and TLS1 are enabled in Windows 7 and Windows 8. On Windows 8.1 and Windows 10, SSL3, TLS1.0, TLS1.1, and TLS1.2 are enabled by default.
[Fix] Media Creation Tool Error 0x80072F8F – 0x20000
To resolve the Media Creation Tool Error 0x80072F8F – 0x20000 error on Windows 7 and Windows 8 computers, enable the TLS 1.1 and TLS 1.2 protocols. Follow these steps to do so:
Method 1: Enable TLS 1.1 and TLS 1.2 via the registry (Windows 7 & 8)
- Make sure your system is fully updated.
- Open Notepad.
- Copy the following lines into Notepad.
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp] "DefaultSecureProtocols"=dword:00000a00 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp] "DefaultSecureProtocols"=dword:00000a00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001
- Save the file with a .reg extension — e.g.,
- Double-click the
enable_tls.regfile to apply the settings into the registry. Click Yes when asked for confirmation.
- If you’re using Windows 7, download the KB3140245 package (TLS 1.1/1.2 enablement update) from Microsoft and install it. This step may not be needed for Windows 8.
- Restart Windows.
- Download registry files: If you wish to download premade registry file(s), download enable-tls.zip. Unzip and run the enclosed file
enable_tls.reg. To reverse/undo the setting to Windows 7/8 defaults, run the
(Credits to Markus for the fix.)
Method 2: Easy Fix (for Windows 7 only)
The above registry fix was created incorporating the suggestions in the Microsoft article titled Update to enable TLS 1.1 and TLS 1.2 as default secure protocols in WinHTTP
The article talks about the Microsoft Update with will enable TLS 1.1 and TLS 1.2 support via KB3140245 package. Here are the instructions:
- Download the KB3140245 package. Don’t run it yet.
- Download the “Easy Fix” executable via the above link (direct download) and run it. The fix will create the
DefaultSecureProtocolsregistry value which is a prerequisite for the Microsoft update.
- Now run the KB3140245 .msi package you downloaded in Step 1.
This automatically enables TLS 1.1 and TLS 1.2 on the computer.
Re-run the Media Creation Tool now. It should work now!
Note that the Easy Fix sets the “
DefaultSecureProtocols” registry value only; it doesn’t write to the
SCHANNEL registry location. But the manual registry fix in “Method 1” above does both! So, if you’ve explicitly disabled the TLS 1.1 and TLS 1.2 protocols via the
SCHANNEL registry modification (e.g., by using the nisudf.reg registry fix to resolve a game/server connectivity issue), then the “Easy Fix” tool won’t help. You need to use “Method 1” in that case.

Your KB3140245 package is not just working as you said,I just followed each and every step you said but when I started this package Then its showing not applicable on your computer
I am having Dell inspiron 15 3000 series having 64 bit system processor and 4 GB RAM on which there should not be problems occuring like this
please help, I am really get much tired of this problem
It appears that your system has a newer update that supersedes KB3140245. In that case, can you just apply the TLS registry fix and let me know if that helps.
I was very sceptical, but this really worked. It was a good surprise. Thanks a lot. BTW this is not an automatically generated comment, I am real, you reading this can also write a comment down below. Cheers!
Merci infiniment !
Ramesh Srinivasan, you are my hero. Thank you my friend.
thanks working 2022 august 28
Thank you! I tried so many fixed for 2 days, and finally your Method 1 solution fixed the problem!
Hi, thank you for the manual how to resolve that issue. Today I had installed fresh Win 7, than SP1 and after that I faced that issue with upgrade to Win 10. I tried your suggestions but without success. But it was strange that even Windows Update do not find updates.
Then I saw that visiting support.microsoft.com face the untrusted SSL certificate root issue. So I found which is the root one “DigiCert Global Root G2” and installed it as trusted root certificate.
And after that, tools starts working. So this issue might be also related not only to protocol version but even to SSL certificate untrust.
@Michal: Thank you for the feedback and additional info. This info should help others.
Michal: You are The Man!
Thanks very much to you and Ramesh for the help. Updating a free to me Win7 laptop to Win10 today.
Amazing! It works! Thank you so much!
Your are my hero.
You need a cape cause are a super genuis.
I was completely lost
your are a savior.
it is working now
Wow, “Method 2: Easy Fix” did the job immediately. Thank you mate!
It worked for me I was stuck and others answers on the internet are not relevant.
i have tried method 2 nd 1 as well. still facing the issue. I got sony vaio e series. Recently formatted the laptop.
this actually worked, first time this kind of site did work. thought it was a joke! or a scam. but it wasn’t. impressive.
Nice the first method works and i did not even need to reboot.
Esta foi a única solução que explica o motivo do problema.
Works first time. tnx.
You legend, i had given up on this machine after receiving that error. thank you. had my doubts editing the registry but all worked like a dream
Hi I have found a further potential cause (which was the cause in my case..)
*error message as at the start of this article with Error 0x80072F8F – 0x20000
*also, seeing ‘invalid certificate’ errors when accessing all web pages.
Obviously, there was a good chance the two were connected.
Eventually I realised that the old, and not used for several years, laptop was displaying a date in 2020. So the incorrect system date was causing a problem, not least as the site certificates were ‘in the future’ as far as the laptop was concerned.
Once I updated the system date to the correct one, the upgrade process started.
You are my hero!! And you saved my day too! Your first method has fixed the problem that I found. Thanks you bro 😀
Worked for me.

@caleb: Download the Windows 10 ISO and mount it to a drive letter. Run Setup.exe. You don’t have to use MCT.

I tried min. 20 “solutions” before this from various sources including official Microsoft support, I even tried ChatGPT and nothing worked for me, finally solved with your solution. Thank you very much!
Solved!! With Method #1 on Windows 7 32bit. Thanks a lot!
Your instructions are a standard for others who mean to help – they should adopt and follow: Clear simple steps, leaving nothing out, with options!
