Google Chrome 94 is here and it has introduced a controversial idle detection API. For those people that do not know what idle detection API is, well basically Chrome can be asked by a website to report when a user of the site has a site open and is idle on the device. The issue that people have with this is that this particular feature can be used to report when the user is not using a computer at all. Good thing is that website or web application will prompt you to allow it to use this feature like when a site/application wants to use your microphone or web camera. Developers are on board with this feature since it can provide them with more telemetric data on how users are interacting with their website/application but there are some that are strongly voicing against this. Tantek Çelik, Mozilla Standards Lead, commented on GitHub, saying:

As it is currently specified, I consider the Idle Detection API too tempting of an opportunity for surveillance capitalism motivated websites to invade an aspect of the user’s physical privacy, keep long-term records of physical user behaviors, discerning daily rhythms (e.g. lunchtime), and using that for proactive psychological manipulation (e.g. hunger, emotion, choice)… Thus I propose labeling this API harmful and encourage further incubation, perhaps reconsidering simpler, less-invasive alternative approaches to solve the motivating use-cases.

Others who have spoken against this feature are people from the WebKit development team inside Apple. Ryosuke Niwa, an Apple software engineer who works on WebKit said:

That doesn’t seem like a strong enough use case for this API. For starters, there is no guarantee that the user won’t immediately come back to the device. Also, who is such a service supposed to know what another device user might be using at any given point? We’re definitely not going to let a website know all the devices a given user might be using at any given point. That’s a very serious breach of the said user’s privacy. It seems to me that such a suppression/distribution mechanism is best left for the underlying operating systems/web browsers to handle.

Of course, technology itself as always can be used for good or for bad and time will tell if this feature has brought good stuff or it has paved another brick in surveillance and privacy manipulation. As said for now option will prompt for agreement and let's hope that it will be used for good causes from this day into the future.

There are cases when you encounter some issues while updating your Windows 10 computer. One of these issues is the error 0x80240034. This particular error is a Windows Update Error that appears on the Windows Update pane every time an update fails to install. When this happens, your Windows Update will only get stuck at 1% and nothing happens afterward and eventually fails. If you click on the View Installed Update History, you will see the error code 0x80240034 for the failed updates. You will see this error each time you try to update your Windows PC. Take note that this issue doesn’t only happen to a specific version of the Windows Update but on various different Windows builds based on many users. What’s more, is that some users are also seeing a different error code when their Windows Update fails but they still end up seeing the error code 0x80240034 when they check the Windows Update history. At the time of writing, it isn’t determined yet what really causes this error but it’s most likely due to some corrupted files in the computer which is why the most common solution you can try is resetting the Windows Update cache. On the other hand, other users also resolved the issue by using the ISO and selecting the “Do not keep previous settings” option during the Windows Update so it might be something to do with transferring the previous settings through the update client. For clear instructions in fixing this issue, refer to the two options provided below.

Option 1 – Try to clear the Windows Update Cache/Distribution Folder

As mentioned earlier, a lot of users tried clearing the Windows Update cache to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Step 1: Tap the Windows key once.
• Step 2: Next, type in “command prompt” in the Windows Start Search, and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Step 3: After opening Command Prompt, type in “net start wuauserv” and hit Enter.
• Step 4: Then type in “rmdir %windir%SoftwareDistribution /S /Q” and hit Enter.
• Step 5: Now type in “net start wuauserv” and hit Enter. Once it’s done, try updating your Windows PC again, it should now work just fine.

Option 2 – Update Windows via ISO file

If option 1 didn’t work for you, you can try this second option of updating your Windows 10 computer using an ISO file which means that you will have to create a Windows 10 bootable media and use it to install the latest Windows 10 version. The most user reported that this option works and the reason why it does have something to do with the Windows Update client since the Windows Updates downloaded from the regular Windows Update client seems to create issues such as the error 0x80240034. However, issues like this one don’t occur when the very same Windows Updates are downloaded and installed via an ISO file. Take note that when using a Windows ISO file, you will be asked to choose what you want to do with the previous settings and apps. A lot of users opted for the “Not to keep the old Windows settings” option which has resolved the issue. So if you want to keep the previous settings then you must try to update Windows first while keeping the old settings. However, if it doesn’t work, you have to try installing the latest version of Windows without keeping the previous settings.

• Step 1: Click this link and then click the Download Tool Now button.
• Step 2: Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Step 3: Now select the ISO file option in step 5.
• Step 4: After that, you should now have an ISO file.
• Step 5: Next, go to the location where you’ve downloaded the ISO file.
• Step 6: Then right-click on the Windows 10 ISO file and select the Open with an option and then select File Explorer.
• Step 7: Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either: Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

If you suddenly encounter the DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL Blue Screen error on your Windows 10 computer along with the error codes, 0x000000D5, 0xb10BBD9E, 0x0D82DA24, 0Xfecd479D, 0x779827CB then read on as this post will provide you some troubleshooting tips that could help you resolve the BSOD error. Getting this kind of BSOD error means that a driver has referenced memory that was freed earlier and it could also mean that the Driver Verifier Special Pool option has caught the driver accessing memory which was freed earlier. Follow the given options below to fix the DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL BSOD error.

Option 1 – Use the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues.

• Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
• After that, select the option “Create custom settings”.
• Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
• Next, select the option “Select driver names from a list” option.
• Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
• Then click on the Finish button.
• Open Command Prompt as administrator and execute this command – verifier /querysettings
• The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
• Open the Command Prompt as admin again and run this command – verifier /reset
• The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 2 – Try updating SSD firmware

If you have installed SSD on your computer recently and you have started getting the DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL Blue Screen error since then you may have to update the SSD firmware. To fix this, you can download the Intel Solid-State Drive Toolbox from the official website. This toolbox is compatible with Windows 10 and Windows 7 and later versions.

Option 3 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 4 – Try running Microsoft’s online Blue Screen Troubleshooter

If running the built-in Blue Screen Troubleshooter didn’t work, you can also try running Microsoft’s online Blue Screen Troubleshooter. All you have to do is go to Microsoft’s website and from there, you will see a simple wizard that will walk you through the troubleshooting process.

Option 5 – Try to reinstall or update device drivers of recently installed hardware

If the first few options didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 6 – Try disabling Hardware Acceleration

You might want to disable Hardware Acceleration system-wide or for a particular program like Google Chrome and see if it resolves the DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL BSOD error

Lately, some users reported getting an error that says, “System doesn’t have any USB boot option, Please select other boot option in Boot Manager Menu” when they tried to reinstall the Windows 10 operating system on their PCs or boot from an installation media. If you have the same problem, then this post should help. This kind of error is applicable to multiple devices by various OEMs and is mostly due to the Secure boot being enabled, or the Legacy or CSM support being disabled. It could also be that the bootable USB device was not correctly made and so on. Whatever the cause may be, here are some suggestions you need to check out to resolve the “System doesn’t have any USB boot option, Please select other boot option in Boot Manager Menu” error and reinstall Windows 10 successfully.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the error. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try to reset the BIOS or the UEFI Settings

If updating the BIOS didn’t help in fixing Error 0199, you can try to reset the BIOS instead.

• Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
• Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
• Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
• Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

Option 4 – Try enabling Legacy or CSM boot support

If the Legacy or CSM boot support is disabled, then it’s no wonder why you’re getting an error. Thus, you need to enable it by following these steps:

• Open Settings and go to Update & Security > Advanced Startup options.
• Next, click on Restart Now to reboot your computer.
• After that, select Troubleshoot > Advanced Options where, you will see more options such as System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• From there, enable Legacy Support and then save the changes and exit. This will restart the computer.
• Once your computer has restarted, check if the error is now fixed.

We tend to move and copy tons of files on our PCs and mostly, the process of copying or moving files, especially if the file has the size of 1GB or up, tends to take quite long. This may be caused by some issues which is why you face slow copy or move speed. So if you are experiencing this issue on your Windows 10 computer, then read on as this post will give you a couple of solutions you can try to increase the speed in copying or moving files. Follow the given instructions below.

Option 1 – 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. It may sound nothing but changing the USB port can actually improve the copying or moving speeds drastically so this should be the first thing you can try to speed up the process of copying or moving files.

Option 2 – Update the USB Controller Drivers

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

You also have the option to update the motherboard and the USB driver from the manufacturer’s official website.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 4 – Try to disable Windows Auto Tuning

Disabling Windows Auto-Tuning can also help in increasing the copying or moving of files in your computer. It is said that this feature improves the performance of programs that receive TCP data over a network by adjusting the receive buffer size dynamically throughput and latency of the link. Thus, if you are trying to copy some data over the network, then the Auto Tuning feature is playing a role here. And in some cases, disabling this feature completely resulted in a lot faster copy speeds over the network.

Option 5 – Try changing the USB Removal Policy

• First, plug your USB drive or external device into your PC and then open This PC.
• Next, right-click on your device and select Properties.
• After that, go to the hardware tab and select the storage media that you want to enhance and then click on the Properties button.
• From there, you can select the Better performance option if you wish for your device to have a better performance. Once you select this option, it will enable write caching in your Windows 10 computer but you need to use the “Safely Remove Hardware” option from the notification area to safely disconnect the device otherwise it may result in data corruption.

Option 6 – Format your drive

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.
