You have a couple of options here:
1) Force windows update to get the Upgrade:
- Step 1: Make sure you have reserved your free copy of Windows 10.
- Step 2: Run Windows Update, and make sure you are set to receive updates automatically.
- Step 3: Navigate to C:\Windows\SoftwareDistribution\Download folder and delete everything in this folder.
- Step 4: Now run Command Prompt utility in Administrator mode. Simply search for ‘cmd’ from Start Menu/Screen, right click, and then click on run as administrator.
- Step 5: Type this command and press enter: wuauclt.exe /updatenow.
- Step 6: Allow the update to download and install
2) Download the ISO and install. You can get the by downloading the media creator tool from:
http://www.microsoft.com/en-us/software-download/windows10
And using the ISO conversion option. Alternatively, you can use the tool to create install media directly.
3) Try manually opening the "Get Windows" (GWX.exe) app from:
OR
- C:\Windows\SysWOW64\GWX (in 64-bit systems only)
If you are unable to run the windows 10 reservation app, try running the following as an administrator (copy to notepad, save as batch file):
REG QUERY "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\UpgradeExperienceIndicators" /v UpgEx | findstr UpgEx
if "%errorlevel%" == "0" GOTO RunGWX
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Appraiser" /v UtcOnetimeSend /t REG_DWORD /d 1 /f
schtasks /run /TN "\Microsoft\Windows\Application Experience\Microsoft Compatibility Appraiser"
:CompatCheckRunning
schtasks /query /TN "\Microsoft\Windows\Application Experience\Microsoft Compatibility Appraiser"
schtasks /query /TN "\Microsoft\Windows\Application Experience\Microsoft Compatibility Appraiser" | findstr Ready
if NOT "%errorlevel%" == "0" ping localhost >nul &goto :CompatCheckRunning
:RunGWX
schtasks /run /TN "\Microsoft\Windows\Setup\gwx\refreshgwxconfig"

It's possible that Windows Update server delay the update. Anyway it doesn't matter, you can just grab the latest ISO rightaway and start upgrading, it will automatically activate as long as you upgrade from 7/8, regardless if you've reserved Windows 10 on that PC
