What to do if JPEG files won’t open in Windows 10
As you know, “JPEG” is one of the commonly used formats for image files which is a compression of digital images. It is one of the topmost used file formats by mobile phones and digital cameras and usually achieves a 10:1 compression with little visible loss in the quality of the image. There are tons of cases as of late, most particularly after the latest Windows 10 update where users were not able to open JPEG files on their PCs. Every time they try to open any JPEG file, they either get an error or nothing happens at all. This issue could be due to the default handler application for JPEG applications not being set or there could be some third-party image viewer not working properly. To fix this issue with JPEG files, refer to the troubleshooting options below.

Option 1 – Try to change the file type association

You need to check if the file type association of the JPEG files are correctly set or not since there are tons of third party programs that change the file type association automatically to themselves without your permission the instant they are installed and so if any of these third-party programs are broken, then naturally, your JPEG files won’t really open. That’s why you can try changing the setting to the default photo viewer instead of the third-party one. To do so, follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type in “control panel” in the field and hit Enter to open the Control Panel.
  • After opening Control Panel, click on the Programs category and select the “Default Programs” option from the menu.
  • Next, select the second option “Associate a file type or protocol with a program” and then select the “Choose default apps by file type” option.
  • After that, click on the .jpg file extension and choose the option from the pop-up.
  • Now restart your PC to refresh all your programs and then see if it has fixed the problem or not.

Option 2 – Try to update your computer

Microsoft frequently releases updates to target bugs and improve users’ experience. And this particular error where JPEG files won’t open is already acknowledged by Microsoft so you need to make sure that your Windows 10 PC is updated to the latest released update and that there are no pending updates.
  • Tap the Win + S keys to open Search and then type in “update” in the field and open the system setting from the search results.
  • After that, check for updates and then download and install them if needed.
  • Now restart your PC once the update is done and check if you can now open JPEG files.

Option 3 – Try to reset the Photos app via Settings

Resetting the Photos app could also help you in fixing the problem. Note that this option will reset all the configurations and your data associated with your Photos and makes the application go into a state when you first started using it and that this option will fix any discrepancies that your application might be experiencing right now.
  • Tap the Win + S keys to open the search bar.
  • Then type in “settings” in the field to open the Settings application.
  • After opening Settings, click the “Apps” category.
  • From there, a list of applications installed on your computer will appear.
  • Navigate through these applications until you find the Photos app and then click on the Advanced options.
  • Afterward, click the Reset button that appears on the next screen. Then a new pop-up comes up and will warn you that all the preferences, as well as sign-in information, will be lost. Click on “Reset” anyway to proceed in resetting the Photos app.
  • Restart your PC once the reset is done.

Option 4 – Try to reinstall the Photos app

Before you start using other third-party image viewers just yet, you can try to reinstall the Photos app first. Thus, if there is something wrong with it, it will instantly get fixed right after it reinstalls. Just take note that this option requires administrative privileges so you need to be logged in as an administrator.
  • The first thing you have to do is tap the Windows + S keys and type in “PowerShell”.
  • Next, right-click on the file and click on the “Run as administrator” option from the context menu.
  • Once PowerShell is opened, execute this command: get-appxpackage *Microsoft.Windows.Photos* | remove-appxpackage
  • The command you just entered will remove the Photos app. After the process is done, go to the Microsoft Store and look for Microsoft Photos then download and install it again.

Solution

Restoro box imageError Causes

Error code 0x80070490 might appear for various reasons but is most prominent in the following cases:

  • Attempts to install Windows 8 or 8.1
  • A corrupted Component-Based Servicing (CBS)

Further Information and Manual Repair

The solutions for error code 0x80070490 vary so users may need to attempt each solution to find the best results.

  1. Repair Corrupted Windows Files with System File Checker

The System File Checker (SFC.exe) is a Windows-based utility that enables users to check and repair corrupted or damaged system files. It can also restore missing systems files which can be the cause of errors such as error code 0x80070490.

To repair files, begin scan by swiping the right edge of the screen then opening the search box. Type Command Prompt, right-click this option, then select Run as Administrator. Once the scan begins, wait for the process to be completed then restart your device. Check if the error is resolved by reattempting updates. If error code 0x80070490 in Windows 8 or 8.1 persists on your device, proceed to the solution below.

  1. Perform Clean Boot

A clean boot is one of the best ways to reduce conflict among files – an issue that may arise whenever users update, install or run programs on their Windows device.

To run a clean boot, your device reboots using limited drives and programs. The process allows you to identify which conflict among programs is causing errors on your Windows device.

You can access the clean boot tool by entering msconfig in the search box. Select Services, then System Configuration. Check the Hide all Microsoft services checkbox then select Disable all. Next, go to the Startup tab, click and open Task Manager. After selecting the Startup tab, make sure you right-click each startup program. Click Disable from the context menu then close Task Manager when done. Select OK on the System Configuration menu then restart your machine to clean boot Windows 8 or 8.1.

If the clean boot successfully identifies and resolves issues with corrupted files, you will be able to access updates using Windows Update or Microsoft Update. Error code 0x80070490 will no longer occur. But if that proves unsuccessful, other options are available below including running Windows Update Troubleshooter.

  1. Run Windows Update Troubleshooter

This method can provide a simple solution for users as it verifies whether your Internet connection, network adapter and Windows Update services are functioning properly. However, if you are uncertain as to whether you will be able to troubleshoot, seek assistance from a qualified Microsoft technician.

To run Windows Update Troubleshooter, simply download from Microsoft’s website. Be sure you are downloading the tool recommended for your operating system, in this case Windows 8 or 8.1. After you download Windows Update Troubleshooter, run it to enable the tool to check for and resolve update issues on your device.

These kinds of hijacks are raising at an alarming rate across the world, and they could be truly nefarious and sometimes harmful too. Browser hijacker malware is created for a number of reasons. These are generally used to force hits to a specific site, manipulating web traffic to generate ad revenue. However, it’s not that harmless.

Exactly how browser hijacker finds its way onto your PC

Browser hijackers can enter a PC by some means or other, including via file sharing, downloads, and e-mail as well. They could also be deployed via the installation of an internet browser toolbar, add-on, or extension.
