Windows10: Microsoft Fixes Search Engine Failure

Search Engine Failure [WINDOWS 10 1909, 2004] The Windows 10 Search Engine was no longer returning any results on the afternoon of Wednesday, February 5. The problem was fixed at the end of the day.

[Updated on 6February 2020 at 12:55 pm]Due to a bug, the Search Engine of Windows10 remained inoperative a few hours in the afternoon of Wednesday 5December. Users opening the OS search field resulted in an empty window where no query could be entered.  The bug was fixed in the evening. Microsoft has not communicated on the origin of the problem. The majority of users should now see the situation return to normal, but a restart is sometimes necessary, says the editor (dixit CNET).

Initially released in July 2015, Windows 10 passed the 900 million active devices milestone in October 2019. A volume that includes Windows 10 terminals such as tablet or PC, but also Xbox One consoles that now embed the OS. According to NetApplications, the operating system passed the symbolic 50% market share milestone in the desktop segment for the first time in August 2019. Its penetration rate rises to more than 54.6% in December 2019. For its part, Windows 7 continues its slow decline, recording 26.6% market share over the same period, compared to 37% a year ago.  Windows 10 and Office 365 updates are now synchronized. They take place twice a year, around April-May and October-November.

Windows 10 2004: what new features are expected?

Microsoft is preparing for the launch of the next Windows 10 update. Code name: 8:01 p.m. Version number: 2004.  Officially named Windows 10 2004(to avoid confusion with older Microsoft products such as Windows Server 2003), this upgrade available in beta (build 19041) would already be near completion.  It is not expected to be released to the general public until April.  Among its main objectives, it aims to achieve a Windows kernel common to all Microsoft’s OSes, including the server version of Windows supporting the Azure cloud of the American group. Among the salient novelties introduced in the pre-versions of this 20h1, we note :

  •  Your Phone app. A brand new application will appear with the 20:1 update. Called Your Phone, it is designed to emulate the screen of an Android smartphone on its computer or tablet. Supporting the Samsung Galaxy S10, S10+, S10e, S10 5G, it allows you to open Android applications, make or answer phone calls on your smartphone from your Windows terminal, but also to access the phone history, synchronize your files, calendar, manage notifications, SMS, MMS…
  • The search engine of the file explorer introduces an autocompletion system displaying a series of document suggestions as the name of a file is entered. It also integrates enriched results from the web giving direct access to various information (weather, news, films on display…).
  • Get rid of passwords. An option to override the Windows 10 login password is now available. Once this is selected, the user will switch to another type of identification, by PIN code or biometric recognition (facial, iris or fingerprint) via the Windows Hello function.
  • Cortana becomes independent. The Cortana voice assistant is detached from Windows and will be the object of an independent application (read the article: Microsoft wants to make Cortana a universal intelligent assistant).  In this logic, Cortana will be entirely decoupled from the taskbar, and will be able to open and manipulate itself like any software window. 
  • Reintroduction of PowerToys. Initially developed for Windows 95 and Windows XP, PowerToys are customization utilities. Microsoft plans to reintroduce them at the 20:1 update. Two PowerToys are currently announced: a guide to Windows keyboard shortcuts, and a feature called FancyZones allowing to reorganize the screen in parts to accommodate application windows.
  • An Alert Centre reviewed. In particular, it introduces the possibility to sort alerts by application or to deactivate them for certain applications.
  • Applications that restart on startup. Modern UWP (Universal Windows Platform) type applications used during the last operating system session can be automatically restarted when the OS is started or restarted, in the same way as web browsing sessions.
  • Redesign of the tablet mode. Microsoft intends to offer a tablet mode screen that is closer to the Windows PC mode than ever before, with just a few differences in terms of touch controls.
  • An optimized version of the Linux subsystem. Designed to run Linux applications on Windows, the Windows Subsystem for Linux (WSL) so far only emulates the Linux kernel API, but does not integrate it as a whole. With the 8:01 p.m. update, he’ll take it on board. Objective: to reduce the launch time of Linux software by optimizing the memory footprint and reducing the number of hardware components required.   

How do I download and install the Windows 10 November 2019 update?

The Windows 10 or Windows 10 November 2019 update (version no. 1909) was released on November 12, 2019. It is now available for all computers and tablets benefiting from Microsoft’s latest opus. In parallel, the publisher will gradually extend the automatic deployment of the November 2019 Update to Windows 10 terminals not yet equipped. All users who have not yet benefited from the automatic update now have the possibility to install it manually. Here’s how to do it.  Make sure you have previously installed the previous OS update (the Windows 10 May 2019 Update), then go through : 

  1. The Settings application,
  2. The Update and Security menu,
  3. The Windows Update menu,
  4. On the Windows Update menu, click Check for Updates,
  5. Then click Download and install Windows 10 version 1909 now.

You must then reboot your device several times for the update to be installed, which takes several minutes. If you are not prepared to wait, you can schedule restarts later. 

Once is not customary, Windows 10 November 2019 wants to be minimalist. It introduces some ergonomic evolutions, for example the possibility to create an event on the fly by opening the calendar above the taskbar. It also optimizes overall system performance, including power consumption for PCs with certain processors. On the enterprise side, Microsoft introduces the possibility to adapt the OS settings in S mode to run Win32 applications from Windows Intune. On the security tool front, it delivers a version of Windows Defender Credential Guard for ARM64 architectures and enhances Windows Defender Antivirus. In other words, this version does not introduce any major new features.

Heading for Windows 10X

The first version 2020 of Windows 10 (20h1) being almost finalized, Microsoft has delivered new betas as part of the continuous development cycle of its OS (build 19536, build 19541, build 19546, build 19551, build 19555, build 19559). Introducing better photo management in the phone application and the ability to create a multi-user Windows account for a family, it should logically point the way to the next operating system updates, but Microsoft does not specify which ones. The only certainty is that Windows 10 updates will remain bi-annual, one delivered in April-May and the other in October-November. According to Sister Mary Jo Foley of, the first will now be a major update while the second will be a minor one.

As a result, Microsoft could give itself the freedom to carry back some of the new features of its current betas in an update already ready for release or, conversely, shift them to more distant intermediate versions. As a consequence, the editor could probably integrate Windows 10X as early as 8:01 pm. This software layer is tailored to power the future Windows touch terminals with double-fold-down screens, expected by the end of 2020. Among them will be the Surface Neo tablet that Microsoft has already previewed (see photo below). Windows 10X may incorporate a new, more streamlined type of Start menu that will usher in Microsoft 365 Unified Search – combining the search engines of Windows, Bing and Office 365. For the time being, it is said to be called Microsoft Launcher by the editor’s in-house teams.
