Slow WiFi in Windows 10

Recently I’ve switched my Internet provider. The new one delivers Internet trough optic fiber to the last mile and the speed should be 100MBit/s. Speed tests over a cable confirm the speed is very close to 100 MBit/s. I however noticed some lags and slowness on my laptop when using WiFi which was not expected. Speedtest.netshowed this:

The results are far away from what I would expect! Again, when attached via LAN cable – everything is fine.

Could not locate bootia32.efi while trying to install Windows 10

Recently a Prestigio smartbook had to be reinstalled with latest Windows 10 1803. This laptop came with 32 bit Windows but had 64bit CPU. So I [wrongly] assumed 64-bit Windows would work. That was not the case!

I’d made 64-bit Windows 10 installation USB stick using Rufus (MBR:UEFI). But when booting I’ve received an error:

[FAIL] Could not locate '/efi/boot/bootia32.efi': [14] Not Found

The reason for that seems to be the cheaper hardware – the CPU was 64-bit, but the UEFI implementation was 32-bit…

Unlike in Linux, for Windows OS there’s one very simple solution: just make 32-bit Windows installation USB stick. Works like a charm!

Running Linux on Windows 10

INTRODUCTION

Often developers and related OPs need to test stuff on Linux (web, cli, .NET Core etc.). The typical approach was to spin up a Virtual machine (VM), install and configure a Linux distro and play with it.

Main Cons include: you need a hyper-visor software, enough RAM, fast hard drive, to fight with basic operations like cope-paste text and files between machines etc.

Well, good news! As of the Anniversary Update Windows 10 supports the so called “Windows Subsystem for Linux” (WSL). It allows you to run natively* most of the non GUI Linux stuff**on Windows without the overhead of a virtual machine.

How to launch Settings panel on Windows 10

In Windows 10 there are two kind of management apps:

  1. Control panel – old fashion / classic app we all know
  2. Settings – the new way of configuring Windows (a XAML app)

Prior to Windows 8, running control panel applets was about pasting strange GUIDs,Control.exe with parameters in RUN dialog or via APIs. You can also use the Canonical names.

In Windows 8/8.1/10 there are more user-friendly commands. For example you can start Windows Update app via RUN dialog:

ms-settings:windowsupdate

This will start Settings >Security > Windows Update XAML app.

Here is a list of most recently used items:

You can find an up-to-date list of all commands here:https://docs.microsoft.com/en-us/windows/uwp/launch-resume/launch-settings-app#ms-settings-uri-scheme-reference
