*** Alternately, if you don't want to get into the registry, you can download and install one of the following files bypassing steps 1 through 6. Only download and install the file for your O.S. version.
If you have tried forcing the upgrade by using the Media Creation Tool, chances are you may have run into a hilarious error which says “Something Happened 0x80070002 – 0x20016″.
(excuse the Windows Snip message – I didn’t notice it until it was too late)
This ridiculously annoying message has been drawing a lot of flak, and several users are actually having a bit of laugh at Microsoft’s expense. And here is how I came across it:
I have a Windows 7 PC, and a Windows 10 Laptop for testing all the preview builds. I have been staring at the desktop’s GWX app which has been sitting quietly on the system tray, ever since the day it first appeared. (Wake up and tell me Windows 10 is ready to download.) I knew I could manually trigger the download, but I just wanted the app to give me the good news, it really would have been a special moment.
Alas! My patience ran out today, and I tried to force the update by entering the “wuauclt.exe /updatenow” command from an elevated command prompt, and then checking for Windows Updates. After that process came to no avail, the next step was to obviously try the Windows 10 downloader tool from Microsoft, and running the Media Creation Tool threw out the “Something Happened” message. That was really helpful Microsoft, thank you. So, what now?
“Houston, we have a problem”.
No we don’t, its actually pretty easy to solve the issue. All you have to do is follow the steps below, which I came across at this thread on Reddit.
1. First, click on start and type the following command to open the Windows Registry Editor
Regedit
2. Now, on the left pane, navigate to this path
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade
3. Right click on the pane on the right hand side, and create a New -> DWORD (32-bit) value.
4. Assign the following name to it. It is case sensitive, so copy and paste it as given below.
AllowOSUpgrade
5. Double click on the entry you created, and change the value to 1 in hexadecimal base. (Hexadecimal is chosen by default)
6. Now you can close the Registry Editor.
7. Navigate to Start > All programs > Windows Update. Wait for it to finish checking for updates, and et voilà!
You should a screen like the one below, which says Windows 10 is ready for download. Click on download and you should be good to go.
Windows 10 is currently downloading on my computer, and should be ready for installation quite soon.
