Windows 10 Hype! But There's no Windows 10 Reserve Notification on My PC?

Yes, Windows 10 is out today. If your computer have a genuine Windows 7/8.1 and not too old (the system specification is good enough for Windows 10), the Windows 10 notification supposed to appeared in the notification area and offered you a free Windows 10 reservation long ago. Unfortunately, there's a little problem that experienced by many people (including me!), which is there's no Windows 10 notification on the notification area until now.

If you googled this problem you will stumbled upon a solution THAT REPEATED IN MANY BLOG AND OTHER TECH SITES (this make me mad because the solution is not working for me and every site just give that same damn solution), which is copy pasting some script that hopefully will fix the GWX (get windows 10) mini apps. This is the script:

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"

There's also another script in case this script just resulted in some infinite loop. The thing is, when I run this script, the command prompt just immediately closed and nothing happened. After I googled some more, it turns out that some value in my UpgradeExperienceIndicators (this registry is mentioned in the script) registry is missing. Thanks to askvg (METHOD 2) I managed to reserve my Windows 10 with their .reg file that add some value to that UpgradeExperienceIndicators registry. So, if you stuck in a problem similar to me, try the .reg file from askvg and restart your computer.

Hope it helps!
