Computer ABC, or cool tricks

To “emulate” Windows XP or an old Pentium processor, you use virtualization software like Oracle VirtualBox or PCem. You’ll need a Windows XP ISO file and install the virtualization software on your modern computer, create a virtual machine, and then install Windows XP within that virtual environment, just as you would on a physical machine. For emulating older Pentium processors and specific hardware, a low-level emulator like PCem is used, focusing on replicating vintage PC components.

For Emulating Windows XP:

  1. Download a Virtualization Program:

Get VirtualBox (for a standard virtual machine) or VMware Workstation Player (another option).

  1. Obtain a Windows XP ISO File:

You will need a Windows XP installation disc image (ISO) file. You can find these from various sources, such as archive.org.

  1. Create a New Virtual Machine:

Open your chosen virtualization software and select the option to create a new virtual machine (VM).

  1. Configure the VM:
  • Operating System: Select “Microsoft Windows” and then “Windows XP”.
  • RAM & Hard Disk: Allocate RAM (e.g., 1GB) and create a virtual hard disk (e.g., 30GB), according to XDA developers.
  1. Install Windows XP:
  • Mount the ISO: When prompted, mount the Windows XP ISO file you downloaded to the virtual machine’s CD/DVD drive.
  • Start the VM: Start the virtual machine, and it will boot from the ISO, allowing you to install Windows XP as if it were a physical computer.
  1. Install Guest Additions/Tools:

After Windows XP is installed, install the “Guest Additions” (for VirtualBox) or “VMware Tools” (for VMware) to get features like shared folders, better display resolution, and USB access, according to the YouTube video.

For Emulating Old Pentium Processors (Hardware Emulation):

  1. Use a Hardware Emulator:

For emulating actual older PC hardware, including specific Pentium CPUs, use a specialized emulator like PCem.

  1. Obtain BIOS Files:

PCem requires you to provide BIOS (Basic Input/Output System) files for the specific PC hardware you want to emulate.

  1. Configure and Use PCem:

Configure the emulator to replicate the desired PC system, including the specific Pentium processor and associated hardware, to run older software or operating systems designed for that hardware.

How to bypass Microsoft account login and no internet during Windows 11 installation?

  1. On the “Let’s connect you to a network” screen, press Shift + F10 to open Command Prompt.
  2. Type:OOBE\BYPASSNROand press Enter.
  3. The PC will restart automatically.
  4. When the setup restarts, you’ll now see an option “I don’t have Internet”.
  5. Select it → continue with limited setup → create your local account.

If you have jagged fonts on your screen, use ClearType.

ClearType - Wikipedia

To “clear” TrueType fonts for sharper text in Windows, adjust the ClearType Text Tuner by typing “ClearType” in the Windows search bar and selecting “Adjust ClearType text” to go through the calibration wizard. ClearType is a Microsoft technology that makes TrueType fonts clearer on screen by using pixel-level rendering.

Using the ClearType Text Tuner

  1. Open the tuner:

Click the Windows icon (Start menu) and type “ClearType” into the search bar. Select “Adjust ClearType text” from the results.

  1. Turn on ClearType:

In the ClearType Text Tuner window, ensure the “Turn on ClearType” box is checked.

  1. Follow the prompts:

Click “Next” to begin the process. You will be shown several text samples; select the one that appears clearest to you on your screen.

  1. Complete the calibration:

Continue to the next screens, choosing the best-looking text samples until you reach the “Finish” button.

  1. Adjust for multiple displays:

If you have multiple monitors, you can repeat these steps for each one to ensure consistency.

What ClearType does

  • Enhances readability:

ClearType is a software technology that improves text readability by making fonts look sharper and smoother on modern displays like LCDs.

  • Works with TrueType:

It’s a technology that renders TrueType fonts on your screen, not a font itself.

  • Customized to your display:

The tuner helps your computer adapt ClearType rendering to the specifics of your monitor.

Sophia Script to take back control of Windows 11

quote
I constantly change Windows 11 settings, tweaking them, so its behavior is less irksome and file management is more efficient, improving my productivity. Making specific changes on Windows often requires too many steps if done through the GUI. But I found Sophia Script (available on GitHub), which lets me fine-tune Windows more easily. It’s a PowerShell module that allows you to fine-tune Windows from the CLI.

The module boasts over 150 functions and is regularly updated. While it runs from the CLI, after getting it running, you are presented with GUI-based options for setting up scheduled tasks (which take forever), managing telemetry settings, properly uninstalling OneDrive, and more. When you click a box to schedule tasks, you can select multiple, and it will do it for you. That saves me a ton of time and makes me more productive.

Spotify has added a new Streaming quality setting: Lossless.

I’m curious which source Spotify used for The Doors: analog master tape or a standard 16-bit 44.1kHz CD.

Before listening to music on your computer, check the capabilities of your sound card.

My laptop sound card is as follows:

Audio Chip

High Definition (HD) Audio, Realtek® ALC3287 codec

It only allows a maximum of 24 bits and 48kHz.

However, full-fledged sound cards in desktop computers can do more.

You could also use a DAC plugged on USB which behaves as a second sound
card…

Of course.
But then someone will write that this is just more electronic waste. :wink:

@davitof

I can also send it to a Hi-Fi system on your home network.

Yes, but a laptop (which usually has a low grade sound board) plus a USB
DAC (for when you want to listen to music from your laptop) will have a
completely different usage and different power needs when compared to a
desktop (don’t forget to take the external monitor into account). Plus
the fact that when you change your laptop (to upgrade it or because it
broke down), you don’t have to change your USB DAC. Which combination
wins, USB DAC + low power usage or good quality sound board + high power
usage? I am unable to answer to this question.

Yes, it’s difficult, yet easy at the same time. :wink:
A laptop has a 100W power supply, a desktop has a 300W power supply. From an environmental perspective, the choice is easy.
However, when playing computer games, the performance of the graphics card (the same model) and the computer in general is also three times lower.

For notebooks, I recommend https://www.notebookcheck.net/

Advice on buying a monitor

Monitor width:

24" - 540 mm
27" - 612 mm
32" - 708 mm

We have the following reasonable resolutions to choose from:

FullHD 1980x1020
WQHD 2560x1440
4k 3840x2160

I have a 27-inch monitor with WQHD resolution.

The pixel size is 612mm/2560=0.24mm

I don’t need to increase DPI. Fonts are legible.

If someone buys a 27-inch 4k monitor, its pixel size will be 612/3840 = 0.16 mm and the font will have to be enlarged.

Moreover, if you play computer games, the graphics card on a 4k monitor has more pixels to calculate, so the FPS drops.

Another example is a FullHD laptop.

In this case, the pixel is 340mm/1980=0.17mm and Windows itself proposes a DPI of 125%.
