Fix Windows Error Code 0x80070017

As you know, the USB security keys are a secure medium to validate a lot of components in a computer. They can be used to log in to Windows 10. Now with the advancement of APIs, you can authenticate across the website as well using the same key. However, there are times when it may not work and it could be caused by several factors. It could be due to corrupted or incompatible drivers or it could also be due to compromised integrity of the key, and many more. So if you happen to encounter an issue with the USB security key on your Windows 10 computer, then there are several potential fixes you can try. You can try toggling the Internet Options settings or reinstall the respective USB drivers. You could also try changing the PIN of the security key or disable the antivirus program on your computer or troubleshoot the web browser. Refer to the potential fixes provided below to fix the problem.

Option 1 – Try to toggle the settings of the Internet Options

• In the Windows Search box, search for Internet Options to open it.
• Next, go to the Security tab and drag the security slider to the lowest possible security for all the given zones.
• After that, click on OK to save the changes made and close the Internet Options.

Note that this option is only a temporary measure as it can make your computer vulnerable. Make sure to press the Reset all zones to default level button.

Option 2 – Try to update or reinstall the respective drivers

If updating the drivers of the device did not fix the problem with the USB security key, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of 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 3 – Try to change the PIN of the security key

If the first two options didn’t work, you can try changing the PIN of the security key. There are instances when the PIN for the security key might have been corrupted. Thus, resetting it can help you resolve the problem.

Option 4 – Temporarily disable Firewall and third-party antivirus

Firewall and antivirus programs are known to block the proper functioning of the USB security key. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.

Option 5 – Try to troubleshoot the web browser

Troubleshooting your web browser can also help you fix the USB security key problem. You can do that by checking if your web browser supports the security key and you can do that by checking on the official website of your browser. You can also try to update your web browser to its latest version but if it didn’t help, you can try to reinstall it or switch to another web browser.

There are a lot of reasons to ban or block different websites in your Windows. From wanting to limit yourself from distraction to block certain sites for sake of kids not going into them. Whatever your reason might be, keep reading in order to find out how you can block any website inside Windows for all browsers. The technique I am going to share with you is universal and not tied to Windows versions, they will work in any Windows from XP onward. Also, the technique will block desired websites on any browser, already installed or even ones that will be installed after doing the trick. And we will also be looking at applications that can help you in this task if you do not wish to do it manually.

Block websites using dedicated software

A small free application called Focal Filter which can be found here: https://www.focalfilter.com/ is a software solution for your needs. It is a pretty straightforward and easy-to-understand application and not really much can be said here about it. You simply download and install it, set your websites, and you are done, the app does rest.

Blocking manually via host file

Another method besides mentioned one using the dedicating application is to manually set site addresses inside the Windows host file. The first thing, of course, is to open the host file, run a notepad with administrator privileges, go to file open, and navigate to c:\windows\system32\drivers\etc\hosts. Once the file is opened go all the way down and add: 127.0.0.1 SITENAME For example: 127.0.0.1 www.youtube.com or 127.0.0.1 www.facebook.com This way each time user on a PC tries to access a listed website computer will reroute it to the given address which is your PC's local address and asked website will not be able to load.

Error 1310 is a fairly common type of error encountered by Windows users. Error 1310 usually generates while a user is attempting to install Adobe Photoshop or some Adobe product on Windows. The message displayed to the user usually states: ‘Error 1310. Error writing to file. Verify you have access to that directory’. Once the error message appears, the installation process will be terminated.

Solution

Error Causes

While there are different conditions that may trigger this error, most likely, they are generated because of the lack of privileges a user has on a Windows log-on. When this happens, the operating system doesn’t allow the user to access the installation files. Another reason Error 1310 may occur is that often users attempt to log on to the system and choose the ‘Only for me’ option rather than the recommended ‘Anyone who uses this computer’. Because of this reason, the data is locked for all the other users. Since Error 1310 can easily disrupt your workflow on the system and may also lead to annoying consequences, it is best advised to treat it as quickly as possible.

Further Information and Manual Repair

There are different solutions to resolve these errors that are briefly listed below as follows.

• First and foremost, restart the installation by logging onto your computer from the administrator account. This error will most likely disappear because there is often a lack of privileges that will trigger it. When you will log on from the admin account, you will have access privileges and such errors will be rectified.
• Fix any corrupt system files that exist on your system. If the file resides in the Windows directory, this error will be generated. Check if any of your system files are corrupt or damaged. If yes, make sure you repair and return them back to their original position.
• This error is sometimes caused because of incorrect registry entries. If the setup program shows errors, it is possible that it is because the system is having problems retrieving data stored in the system registry.
• Another way, this error can be avoided is to run the setup in compatibility mode. Compatibility issues are a common occurrence. However, when an installation is performed in the compatibility mode, one can easily steer clear of such errors.

Implement any of the solutions listed above and protect your system against Error 1310.

It is no secret that Microsoft is trying to keep Windows relevant and that it is trying to make it as good as possible. A new Windows update will bring some interesting stuff in it which well some like it, some not so much. Among various technical and security updates Microsoft will bring some directly visible to each user.

First

of these features will be File explorer compact mode. This feature is a sort of spacing content in file explorer giving it easier access if you are using a touch screen device. Now, this feature is somewhat strange, and altho I can understand and get behind the logic of this move I am not sure I like it. Lucky for me and others who feel the same this option can be turned off for now.

Second

feature is something I can get behind, improvements for virtual desktops. There is an article on errortools about virtual desktops feature and I really hope you are using it since it is a great feature. Anyway, new update will bring us separate desktop wallpapers for each desktop and we will be able to arrange them in order we like.

Third

thing that I would like to address is animation features. We will have windows slowly fade and resize when opened, minimized, maximized, etc. So far we are unable to tell how this can and will it affect overall system performance. I am sure it will have some impact but hopes are that it will be kept to a minimum.

Recently Logitech has released a new line of ergonomic mouse products on market, strangely shaped and lifted on a vertical axis Logitech claims that these devices will fix your issues and ease your hand pains for prolonged use of the computer.

The first time I saw this mouse I was not really impressed with its looks and somehow I thought it will not feel good. This all changed when I actually started using it, surprisingly altho strange in looks it does feel much more natural and much less stressful on hand. Also, it felt like I have used it before, personally, I did not need any adjustment period in order to use it fully.

All of that being said I will admit that using it for gaming is still not an option for me, someone might find it ok, especially if they play some games that do not need to be responsive like strategies or similar but for RTS and FPS I will still stick to the typically shaped mouse. This might be just a habit for me but somehow I feel more responsive with the typical mouse, but for anything else, this is the mouse that will keep your hands stress-free.

Now in order to get the mouse to be really recommended it needs to have some good technical specifications as well, looks are not all. The less important detail is that the mouse comes in 3 different colors: Black, white and pink, and its technical specifications are:

Specs & Details

Dimensions

Height: 71 mmWidth: 70 mmDepth: 108 mmWeight: 125 g

Technical Specifications

Sensor technology

• Sensor type: Logitech Advanced Optical Tracking
• Dpi range: 400-4000 dpi (Fully adjustable with 100DPI increments)
• Nominal value: 1000 dpi
