If your USB keeps disconnecting and reconnecting after you connect your USB device on its own randomly, then the problem might have something to do with a hardware or driver issue. The first thing you have to do in such a case is to make sure that the device is working on another computer. This will help you isolate the problem and if it turns out that it works, then the problem lies in your computer and not your USB device. To fix this connection problem between your USB device and Windows 10 computer, you can use the options given below as a reference.

Option 1 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 2 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.

Option 3 – Try to turn off the Power Saving option

You could also try to turn off the Power Saving option to resolve the problem. All you have to do is switch to Power Management after you select the Properties of the USB device and from there, uncheck the “Allow the computer to turn off the device to save power” option. On the other hand, if you are using a laptop and did not use the USB device for a long time, then it could be powered off. This will ensure that the system does not turn off the USB device.

Option 4 – Try to reinstall the latest Universal Serial Bus controller drivers in Compatibility Mode

If you were unable to install the Universal Serial Bus controller drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 5 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Hello and welcome to How To Speed Up PC Startup where we will explore how to make your PC boot-up system faster. When your computer gets older, you'll see a decrease in your PC's load time. This can be very annoying and frustrating, especially if you're not accustomed to exercising patience. Your computer's boot time does not need to be sluggish, even if it's old. While there are reasons why your computer is acting up and giving you the 'slow' sign, there are ways that you can optimize how fast your PC starts up at the beginning. Once you start speeding things up, you’ll never look back!

Start With your BIOS

You may need to tweak your PC’s start-up menu. Since the majority of issues encountered on your PC might not be related to the software running in the back end, you can focus on your computer's hardware. The ideal way to speed up your PC startup is to access your computer's BIOS when booting up. This can be accessed by holding the DEL key or whichever button is used to tap into your BIOS. You can change where your computer boots from. You can opt to put your hard disk right at the top which would elude searching for CDs and other storage media devices when your PC starts up.

Tweak Startup Programs

There are many programs that execute when your computer starts up. These programs normally run in the back end. Most times back-end programs are unnecessary and do not contribute to the productivity or performance of your computer when in use. Instead of allowing these programs to execute when your PC boots up, why not disable them?  By deactivating these programs, you'll be reducing the amount of CPU usage which will accelerate your PC performance. Additionally, there are some installed programs that you never use. Instead of leaving these programs to occupy needed space on your computer system, you can uninstall these to create more room on your computer. This actually increases your PC startup speed.

Put Malware on a Leash

Malware and spyware can cause problems for your start-up. A slow computer is an indication that your computer is plagued by malware. This affects your computer's boot time and whether or not it'll startup as quickly as you intend it to. If your computer gives you the 'virus alert', you need to download an antivirus program that will be able to eradicate all virus threats. Be mindful of where you download antivirus programs since many of them are viruses or have viruses attached to them. Some viruses are tough on your computer. This means that if an antivirus works for your best friend, it may not work for you. Since malware differs in functions and the havoc they cause, it's best to know what you're up against by doing research.

Clean Your Registry

You should also clean out your registry. The fewer unused registry keys you have lying around on your computer, the faster your computer will go. Getting a good registry cleaner from a clean source can help tremendously, but be careful; registry cleaners have the potential to be very dangerous so make sure you backup everything on your computer and only download registry cleaners from a reliable source. By implementing the above tips, you'll see quick improvements when using your computer.

Windows 10 and Windows 11 have automatic dynamic screen brightness depending on the surrounding light inside the room. Please take note that this option is available only on devices with build-in screens like laptops, tablets, and all in one desktop PC. If you are connected with your PC via an external monitor you will not have these settings available and probably feature is not even working.

Some computers will also allow automatic brightness changes also on what is displayed on the screen. This option is meant to save battery life on devices. Microsoft calls this automatic brightness feature Content adaptive brightness control. In order to change this setting, we will go to settings inside Windows.

Disabling automatic brightness inside Windows

Open Settings inside Windows, in Windows 11 press WINDOWS + I to open settings, then click on the system in the sidebar and then go to Display. Click on the small arrow beside the Brightness slider in order to expand a small menu and then uncheck Help improve battery by optimizing the content show and brightness. If you see Change brightness automatically when lighting changes, uncheck that as well. Close the settings and you are good to go, now brightness will always be as set in settings.

Inside Windows 10, go to Settings and then go to System and then in Display under the Brightness and Color section look below and locate the box that says Automatically adjust contrast based on the displayed content to help improve battery and uncheck it, if the box below with text Change brightness automatically when lighting changes exists, uncheck it as well. Close settings and you are done.

Hello and welcome everyone, today we will be talking about power toys, a great, completely free, open-source, Microsoft-supported Windows project which aims to provide Windows itself with powerful features not found natively in it. We will explore power toys completely here and explain each module and its features. The first thing is of course to download power toys themselves. You can find them here. After you download them, double click on the downloaded file and install. Start power toys, you will find them at the bottom of the taskbar, note that power toys need to be active in order to use their features. When opened you will be greeted with general settings window. These are settings for power toys themselves, Here you can check for updates, change the looks of power toys, run it on system startup and run them as administrator. Set them up so they best suit your needs.

Color Picker

Moving down next tab we have is Color picker. The color picker will let you as the name suggests pick colors, it will sample colors from running applications and windows, snap their values, and place them in the clipboard. A useful application if you are working as a graphic designer, want to create some cool word document, or just want to compare the difference between colors. After the Color Picker is activated, hover your mouse cursor over the color you would like to copy and left-click the mouse button to select a color. If you want to see the area around your cursor in more detail, scroll up to zoom in. The copied color will be stored in your clipboard in the format that is configured in the settings (HEX by default). The editor lets you see the history of picked colors (up to 20) and copy their representation in any predefined string format. You can configure what color formats are visible in the editor, along with the order that they appear. This configuration can be found in PowerToys settings. The editor also allows you to fine-tune any picked color or get a new similar color. Editor previews different shades of currently selected color - 2 lighter and 2 darker ones. Clicking on any of those alternative color shades will add the selection to the history of picked colors (appears on the top of the colors history list). Color in the middle represents your currently selected color from the history of the colors. By clicking on it, the fine-tuning configuration control will appear, which will let you change the HUE or RGB values of the current color. Pressing OK will add newly configured color into the history of the colors.

Fancy Zones

Moving down, we have fancy zones. FancyZones is a window manager utility for arranging and snapping windows into efficient layouts to improve the speed of your workflow and restore layouts quickly. FancyZones allows the user to define a set of window locations for a desktop that are drag targets for windows. When the user drags a window into a zone, the window is resized and repositioned to fill that zone. When first launched, the zones editor presents a list of layouts that can be adjusted by how many windows are on the monitor. Choosing a layout shows a preview of that layout on the monitor. The selected layout is applied automatically.

File Explorer

Next, File Explorer. Only 3 options here but maybe some are important to you. This extension lets you enable SVG file preview in File Explorer, enable Markdown preview, and enable SVG thumbnails. Turn on each one you might need.

Image Resize

Next down the line, we have Image resize. Image Resizer is a Windows shell extension for bulk image-resizing. After installing PowerToys, right-click on one or more selected image files in File Explorer, and then select Resize pictures from the menu. You can specify your own sizes if you want, you can resize when dragging files, you can overwrite files or make new copies of new sizes, and many more options. A very useful tool I am sure plenty of users can use since this eliminates the need for pictures or any other image application for common resizing tasks.

Keyboard Manager

The keyboard manager is the next tab in power toys. The PowerToys Keyboard Manager enables you to redefine keys on your keyboard. For example, you can exchange the letter A for the letter D on your keyboard. When you select the A key, a D will display. You can also exchange shortcut key combinations. For example, the shortcut key, Ctrl+C, will copy the text in Microsoft Word. With the PowerToys Keyboard Manager utility, you can exchange that shortcut for ⊞ Win+C). Now, ⊞ Win+C) will copy text. If you do not specify a targeted application in PowerToys Keyboard Manager, the shortcut exchange will be applied globally across Windows. PowerToys Keyboard Manager must be enabled (with PowerToys running in the background) for remapped keys and shortcuts to be applied. If PowerToys is not running, key remapping will no longer be applied.

Power Rename

Nex we have a very cool and powerful Power Rename PowerRename is a bulk renaming tool that enables you to:

• Modify the file names of a large number of files (without renaming all of the files with the same name).
• Perform a search and replace on a targeted section of file names.
• Perform a regular expression rename on multiple files.
• Check expected rename results in a preview window before finalizing a bulk rename.
• Undo a rename operation after it is completed.

Run Utility

Power Toys Run utility follows next. PowerToys Run is a quick launcher for power users that contains some additional features without sacrificing performance. PowerToys Run features include:

• Search for applications, folders, or files
• Search for running processes (previously known as WindowWalker)
• Clickable buttons with keyboard shortcuts (such as Open as the administrator or Open containing folder)
• Invoke Shell Plugin using > (for example, > Shell:startup will open the Windows startup folder)
• Do a simple calculation using the calculator

Shortcut Guide

Last but not least we have a Shortcut guide. This guide uses PowerToys to display common keyboard shortcuts that use the Windows ⊞ key. Windows key keyboard shortcuts can be used while the guide is being shown and the result of those shortcuts (active window moved, arrow shortcut behavior changes, etc) will be displayed in the guide. Releasing the Windows ⊞ key will make the overlay disappear. Tapping the Windows ⊞ key will display the Windows Start menu. Hey, you made it till the end, thank you for reading and I hope to see you soon.

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue. There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

• In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
• Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
• Click the OK button and then restart your computer.
• Now try to use VirtualBox again and see if the problem is fixed.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

• Open VirtualBox on your computer and select the virtual machine.
