Windows 10 Clock in UTC

If you are running Windows and Linux in dual boot, you will soon find out, that the clocks are not matching. Most probable the reason is that Windows by default expects the computer time to be set to local time, while Linux assumes it to be UTC.

I consider the approach of Linux the better one: The BIOS/UEFI system time is there set to a global harmonised standard, UTC. The operating system then translates this to the local time. This means you can install as many operating systems in parallel without interference of them with the system time - just immagine if you have for example, Windows, FreeBSD and two Linux distributions on your computer and every one of them wants to account for daylight saving time .... When setting the system clock to UTC, this problem will never arise.

Setting Windows to use UTC as system time

Registry magic! Create a new registry key named RealTimeIsUniversal.reg with the following contents.

Alternatively you can create a QWORD (or DWORD for 32-bit Windows) with the value "1" in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\RealTimeIsUniversal

Then reboot Windows and set the time zone to UTC

If unsure, try another reboot to check if the settings persists, but that should do the job.

Cortana Go Away!

With tomorrow's Anniversary Update for Windows 10, Cortana becomes the Windows-Internal search engine with Online access, regardless if the user wants it or not.


Getting rid of Cortana

According to this article you can still disable Cortana by editing some values in the registry:

To disable Cortana for the machine: Set the DWORD value "AllowCortana" in the path "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search" to "0".

In case you want to disable Cortana just for the current user, use HKEY_CURRENT_USER instead of HKEY_LOCAL_MACHINE.

I've not yet tried it, since I'm still waiting for the Update. In case you don't want to mess up with the registry, you can download the Regkey-Files on the article page.

In a nutshell

In the Registry-Path
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windows Search

Set the DWORD Value "AllowCortana" to 0 do disable it for the whole machine. Use HKEY_CURRENT_USER instead of HKEY_LOCAL_MACHINE if you want to disable it for your user only.

Cortana becomes a Must-Have

Good news for Windows 10 users:

You won't be able to turn off Cortana once the next obligatory update comes out.

Yes, Microsoft has decided for you, that Cortana is so awesome, that you should never ever just think on turning that stupid thing off.

I really hope that Steam OS takes over the games market, so I can finally get rid of Windows for good. That's anyway the last use case where I'm still stuck on Windows sometimes.
Oh by the way: Just as a random conspiracy theory because it fits so well here: Microsoft wants to make Steam buggy and broken, so Users switch to the (also buggy and even more broken) Windows Store.

I'm really looking forward to the release of ReactOS.

Stay in touch. Once it is official and I find a way to get rid of this feature I'll tell you how you can also do this [and here it is].
