A lot of Windows 10 users prefer the black theme on their computers and when you see anything but black it can get quite annoying. Such as is the case of the Taskbar which, as you know, is usually dark, however, when you take a look at the Cortana search bar, instead of seeing black, you’ll see that it has turned white. To fix this issue, read on as we will provide you some options you can try to set the Cortana search bar back to black. Before you proceed, take note that the options provided below will change all white search boxes to black and that one of these options needs administrative privileges.

Option 1 – Try changing the default App mode

As you know, Windows 10 has two modes, namely the Light and the Dark. Thus, you can switch to the Dark mode so that your Cortana search bar will be black as well. However, remember that it will completely change everything into dark mode so there will be no more Light mode elsewhere.

• First, you need to click on the Start button and then click on the cog icon to open the Windows 10 Settings.
• Next, from the Settings Menu, select Personalization and then select Colours from the left pane.
• Then scroll down until you see the “Choose your default app mode” option and select “Dark”.

After you apply the changes, it will change the Cortana search bar into black instantly. Aside from that, you will also see the User Interface changing into dark mode.

Option 2 – Try changing the Registry value

If you are well-versed in editing registry keys, then you need to try this option. But before you go over the steps below, make sure that you create a System Restore point first so that if anything goes wrong, you can always go back to how it was before the changes were applied.

• Tap the Win + R keys to open the Run prompt.
• Then in the field, type in “regedit” and hit Enter to open the Registry Editor. If a User Account Control prompt appears, just click Yes.
• Now that you’ve opened the Registry Editor, navigate to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionSearchFlightingWhiteSearchBox

• After that, double-click on the “Value” key located on the right pane and set the value to “0” instead of “1” and then click Ok to save the changes made. You should now see a black or grey text box color instead of white.

Option 3 – Try changing the Region

In some forums, a lot of users stated that changing the Region also worked out for them in changing the white Cortana search bar to white. Thus, you need to change the region settings of your computer temporarily. To do so, follow the steps below.

• Type in “Regional Settings” in the box and then click it as soon as it appears from the search results.
• Next, make sure to select a region where Cortana is not available.
• Then select apply to that region. After that, it will change the Cortana search bar color to black.
• Now sign out and sign back in and revert to the original settings. But the changes you made earlier in Cortana will still remain.

When your computer is slow, you don’t have much choice but to wait until it gets done with a task at its own pace, albeit a slow one. So if you want to switch user accounts on your computer a couple of times daily, then a slow computer can get really irritating. What makes system processes slow is that the accounts have some programs or applications running and resources allocated to them. And besides, if your computer is already low on performance, it will kill the natural fluidic flow of the user. But worry not, for this post will guide you in switching user accounts with the help of some minor tweaks in your Windows 10 computer. To disable or enable Fast User Switching, you have two methods to do that using the Registry Editor and the Group Policy Editor. Either way, refer to the instructions laid out below.

Option 1 – Enable or disable Fast User Switching via Registry Editor

• After that, type “Regedit” in the field and tap Enter to open the Registry Editor.
• Next, go to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem
• Then right-click on System and select New > DWORD (32-bit) Value and name this newly created DWORD as “HideFastUserSwitching”.
• Now double click on it. If you want to enable Fast User Switching, input “0” as the value, and if you want to disable it, input “1” as its value.
• Restart your PC to successfully apply the changes made.

Option 2 – Enable or disable Fast User Switching via Group Policy Editor

Take note that this option will not work if you are using the Windows 10 Home edition since the Group Policy Editor does not come with Windows 10 Home. Refer to the steps below to enable or disable Fast User Switching using Group Policy Editor.

• Tap the Win + R keys to open the Run dialog box and then type in “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.

Error Code 0x80070017 is an error code that is most often associated with Windows 10 installations, although it has also been encountered by users on previous versions of the Windows operating systems. It is usually encountered as users attempt to install a new version of the software on their machine.

Common symptoms include:

• A vague error message regarding the inability of the system to copy over the necessary files pops up as users attempt to install a new version of the Windows operating system on their computer

While it can be hard to tell what the exact cause of Error Code 0x80070017 is on your specific device, the good news is that there are two primary methods that can be used to fix the problem and to allow you to proceed with your installation. These two methods do require some degree of technical knowledge and/or skill, so if you don’t feel like you have the ability to undertake them on your own, be sure to get in touch with a trusted computer repair professional to assist you.

Solution

Error Causes

The most basic cause of Error Code 0x80070017 is that some of the files that are needed by the system to complete the installation are either not being found by the computer or are believed to be corrupted by the system. When this happens, security features within the software prevent it from completing the installation process, so as to avoid damage to the computer. Error Code 0x80070017 can be disruptive to your installation process, but there are two basic methods that can be employed to resolve it.

Further Information and Manual Repair

While it can be frustrating to encounter Error Code 0x80070017 on your Windows machine, there are two methods that can be used to try to resolve the problem. One of these methods is extremely simple, even for the most basic users, while the second method takes a little bit more skill and technical knowledge. If you aren’t able to complete these methods on your own, be sure to get in touch with a qualified computer repair technician that can assist you. Here are the best ways to attempt to resolve Error Code 0x80070017 on your device:

Method One:  Clean Your Physical Disk

If you purchased a physical disk version of the installation files for your Windows operating system, remove the disk from your drive and clean it using a microfiber or other lint-free cleaning cloth. As you wipe down the disk, do not use any chemicals, and be sure to wipe gently from the center towards the outside edge rather than the other direction, as failure to do so can damage the disk irreparably.

In some cases, you may need to contact Windows support if you believe that there is an error on the disk itself, such as a scratch, that would prevent the disk from being used as needed in the installation process. They may be able to offer you a replacement disk or you may be able to download a digital copy of the version that you are attempting to install on your machine.

Method Two:  Use the Chkdsk Utility

To determine if there may be an error within the disk drive itself, place the installation disk into the drive and restart the system. Go through the prompts until you see the option to “repair your computer.” Choose the operating system that you are using, go into the menu for System Recovery, and type in the words “Chkdsk/r” to begin to use the tool.

Whenever you run a tool like Chkdsk on your computer, it is important to restart your machine afterward to ensure that any changes that have been made are able to be fully applied and accepted by the operating system that you are running.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

In this post, you will be guided on how you can set up the USB tethering feature on your Windows 10 computer and share your mobile device’s mobile data so other devices can also access the internet. Tethering is usually known as Wi-Fi tethering which allows users to share mobile data to any device with Wi-Fi, laptops included. This is really useful especially when you have no other way to access the internet. For instance, if you are using a desktop computer and there is no way for you to connect to the Ethernet, and you have no Wi-Fi adapter that you can use to connect to a router as well, you can use USB tethering instead to access the internet. It is almost similar to Wi-Fi tethering except that it works over a USB connection instead of a Wi-Fi adapter. USB tethering is almost quite the same as an Ethernet connection except that it’s faster compared to Wi-Fi tethering as well as Bluetooth tethering. Just like Wi-Fi tethering, USB tethering is free unless your network carrier has blocked it. Thus, it’s better if you make that clear with your operator. Once you have that covered,

Follow the instructions provided below to set up USB tethering on your Windows 10 computer.

Step 1: First, connect your mobile device to your Windows 10 computer using a USB cable. Step 2: If it asks you to enable the file transfer feature, just cancel it. A prompt that says, “Tethering or Hotspot active—Tap to setup” should be available as soon as you get connected – tap on it. Note: If there is no prompt, just go to Settings > Network and Internet > Hotspot and Tethering and from there, toggle on the USB tethering option. Step 3: Afterwards, the setup will create a new network adapter in Windows 10 automatically and your computer should now be connected to the internet using USB tethering. Note: You have to make sure that the Wi-Fi connection in your mobile device is turned off and if it is connected to an existing network, the USB tethering will be disabled but if you see its status as enabled, then the USB tethering setup is successfully done. In addition, keep in mind that the location of tethering can be different for every phone, especially on a customized operating system such as RealMe, Redmi, Samsung, and any other mobile device although they are clubbed in the section of Mobile and Data Network. In case you encounter some problems when using USB tethering in your Windows 10 computer, there are troubleshooting tips you should follow. The NDIS-based Internet Sharing Device network adapter is what Windows 10 uses to make USB tethering possible so if it stops working, follow the options provided below.

Option 1 – Perform basic check

The first thing you can do if you encounter problems in USB tethering is to do a basic check like checking if Wi-Fi is enabled automatically as well as check if the USB cable is disconnected or if you’ve turned off USB tethering accidentally.

Option 2 – Try installing or updating the USB RNDIS adapter

RNDIS or Remote Network Driver Interface Specification can also help you resolve any USB tethering problem. If the pre-installed driver does not help you in connecting to the internet, then you can try installing the USB RNDIS driver that is, if it’s not installed yet. If it is already installed, you can try to update it instead.

• Tap the Win + R keys to open Run and type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• Next, expand the Network adapters section and look for the Remote NDIS based Internet Sharing Device. But if you are using a Samsung smartphone, you might see “Samsung” instead of under Network adapters.
• Right-click on it and then select the “Update driver” option.
• Then select the “Browse my computer for driver software” option.
• After that, select the “Let me pick from a list of available drivers on my computer” option.
• Now uncheck the checkbox for “Show compatible hardware”.
• From the given list on your left-hand side, look for Microsoft and then select the Remote NDIS based Internet Sharing Device on your right-hand side.
• Click on Next. A new popup will appear where you have to click on Yes. This will install the driver.
• Now click on the Close button and restart your computer.

Over time Applications change, some for the better some for worse. Some of them even stop receiving updates and are old and vulnerable. Sometimes standards change and some file types are not used anymore. Software evolves along with technology and that is good. Keeping old and useless applications inside your Windows is not so good. From various exploits to simply taking up space, maybe even slowing down OS it is always wise and good to clean your Windows from unwanted old applications. In this article, we will be mentioning some relics of old and providing you with an explanation of why you should remove them from your system if by any chance you still have them on it.

Silverlight

Silverlight was meant to be a competitor for Adobe Flash, it is a WEB framework that enables rich media content inside your WEB browser. The issue is that it is not developed anymore and today's browsers do not support it. The only browser that actually can support it is internet explorer which itself is not supported and how there is practically 0 content on today's modern WEB that will require Silverlight, it is safe and recommended to remove it.

Adobe Flash

Speaking of Adobe Flash, you should remove it as well. Flash has stopped receiving support as of January 2021 and browsers have dropped support for it and even blocked it due to security issues. However, there still might be some local installation of Flash itself inside Windows along with the old Shockwave player that stopped receiving support in 2019. You should remove them both.

JAVA

Now this one is tricky, by itself JAVA does not present any security issues since browsers do not support it anymore and the desktop version is not really slowing down your computer. This one has simply put just another media runtime that is not used and simply takes up space and resources. However if you have some applications that you do use that rely on it (I can really just think of JAVA Minecraft at this point) leave it of course but in any other case, it is just purely not needed.

Quicktime

While we are at media runtime and stuff that just simply is not needed, Quicktime is one of them. Now this Apple Video player and codec is still pretty developed and active in Apple’s iOS environment, Windows version has not been updated since 2016 and it was discovered that it contains some critical vulnerabilities. Uninstall it and if you need a player that could play MOV files, just use a VLC player that can play them without any separately installed codec.

uTorrent

This one, the same as CCleaner was once a good application, as a matter of fact, it was the best torrenting application. Sadly it has fallen from its grace very low, from getting tons of ads in its interface to findings in 2015 that code of torrent client was packed with a crypto miner that used system resources of an installed computer to mine crypto without user’s awareness. You should uninstall this torrent client if you would like to get your PC back and not provide it for cryptocurrency mining for the company that developed it. Use qBittorrent or TIxati, open-source and free ones that have everything needed for any torrenting needs.

Toolbars and Browser extensions

There are a lot of toolbars for browsers and extensions that are malicious in nature or simply not updated providing security issues. It is very advisable to remove this as soon as possible.

WinRAR

WinRAR has gained its large popularity solely for the reason that you could download it from the official site like shareware and use it forever. The license never expired and you could use it indefinitely. Sadly not much has been improved in the application itself and it is slowly falling out in its range of what it can do. There are better open source and free options today like 7zip, PeaZip, ZIPvare, and more that are working the same as WinRAR if not even better.

Windows and manufacturers Bloatware

Yes, applications that come bundled with Windows and with some laptops that include manufacturers made software for different tasks like its own specific media players, calculators, etc. It is known that these applications are not better than their open-source rivals and there are too many of them including some that you will probably never use. It is the same as buying a new phone bundled with tons of applications that you do not need, did not ask for, and do not use. Delete all of them. Considering Windows there are also some Store application like Candy Crush Saga demo and other are safe to remove if not needed. That’s it, our advice for old and not needed applications so you can keep your PC safe and fast.

There is one service in the Windows operating system that is responsible for managing all the print jobs as well as handles the interaction with the printer. This service is known as the Print Spooler service. However, if it stops running, then you won’t be able to print anything on your computer. In such a case, you can try to restart the Print Spooler service, and to do that, you have to open the Windows Services Manager and look for the Print Spooler Service. Once you found it, right-click on it and select Restart. If it isn’t running, select Start and if the Service starts working again, then good but if not and you got an error message instead that says, “Windows could not start the Print Spooler service on Local Computer, Error 1068, The dependency service or group failed to start”, then read on as this post will give you a couple of suggestions you can try to resolve the issue. The reason why you could not start the service is most likely because the Print Spooler service is dependent on other services which might not be properly running. If the following services are not running then it’s no wonder why you’re getting the error.

• HTTP Service
• Remote Procedure Control (RPC) Service

You might not see the RPC service which means that the Print Spooler Service does not recognize its dependency on the RPC service. In such a case, you have to manually configure the dependency by following the options given below.

Option 1 – Try configuring the dependency via CMD

The first thing you have to do is to configure the dependency using CMD. Refer to the steps below to do so:

• Open an elevated Command Prompt.
• Then type in “sc config spooler depend= RPCSS” and hit Enter.
• After the command has been executed, restart your computer and then check if it fixed the problem. If not, proceed to the next given option below.

Option 2 – Fix dependency via the Registry Editor

You can also resolve dependency using the Registry Editor. How? Refer to these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesSpooler
• Next, right-click on the “DependOnService” entry located on the right pane and select Modify.
• Now change its value data to “RPCSS” and click OK to save the changes made and then exit the Registry Editor.
• Reboot your computer and see if the issue is resolved.

Option 3 – Try running the Printer Troubleshooter

Another option you can check out is the Printer Troubleshooter. This built-in troubleshooter in Windows 10 can help you fix most print issues. It checks if you have the latest printer drivers and then tries to fix and update them automatically. Aside from that, it also checks if you have connectivity issues or if the Print Spooler and the required Services are running fine. To run it, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

BIOS is software that is running in a chip located on your motherboard, you can enter BIOS usually by hitting DEL once the computer is turned ON but this sometimes varies and it depends solely on the motherboard manufacturer. Inside BIOS you can configure your computer components and set up some other important things including passwords for BIOS itself or for the entire system. Password itself is meant to protect access to BIOS from other non-technical users or to prevent access to the system from other people if for example computer is in one household and you would like to be the only one having access to it. However, passwords can be forgotten, and sometimes you can even purchase a second-hand computer with a password on it. In this guide, we will lead you through ways on how to remove your BIOS password so you can regain access to your BIOS settings.

1. Use Manufacturers master password

   Most motherboard manufacturers have built-in a couple of master passwords for BIOS access. If your motherboard has one you can easily find it on the manufacturer's website. Use the master password and remove other passwords inside BIOS, save and exit.

2. Remove CMOS battery

   If you could not find the manufacturer's master password or your motherboard model does not have one remove the CMOS battery to reset BIOS. Note that this method will reset the whole BIOS not only the password. Open on side of your computer casing and locate the round battery on it, do not worry, there is only one battery so you can not make mistake. Remove the battery and leave it outside for around 20 to 30 minutes then place it back as it was, CMOS is reset now and you can access BIOS.

3. Reset BIOS via jumper

   If you want to remove only the password and do not touch other BIOS setting you can locate the BIOS password reset jumper. How the location of this jumper and position is different from the motherboard to motherboard we can not cover them all here and it is advisable to read the manual or find information on the official manufacturer's website.
