Fix Screen Aspect Ratio issues in Windows

While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

Option 3 – Bypass the Certificate Revocation Check

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.

• In the search box of your browser, type “internet options” and open it once it appears.
• After that, go to the Advanced tab and navigate to the Security subheading.
• Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
• Now restart your computer. Upon the next startup, try opening the website again. This time, your browser will stop checking it for certificate issues. However, it’s not safe to leave those options unchecked so make sure that once the website’s SSL certificate is fixed or once you no longer have to visit that website, you recheck those options.

One of the cool and interesting features in Windows is the Screensaver which allows users to display animation or change the wallpaper automatically when the computer is not being used. This feature can also time out and lock your computer when it remains idle for quite some time. However, if you notice that the screensaver of your computer turns on a lot earlier, then you’ve come to the right place as this post will guide you on how you can change the timeout settings of the screensaver of your Windows 10 computer. Usually, the screensaver in Windows 10 is turned off by default, however, if some other user has turned it on or if you have turned it on, you can actually change the timeout settings of the screensaver using several methods. You can do it through the Personalization settings, Registry Editor, as well as the Group Policy Editor. Before you proceed with the instructions provided below, make sure that you create a System Restore point first. Once done, follow each one of the suggestions carefully to successfully change the Screensaver timeout settings in Windows 10.

Option 1 – Modify the timeout settings of Screensaver via Personalization settings

Researchers have discovered 16 vulnerabilities in Bluetooth connections that could be exploited and make from minor to some serious damage to your device. The flaw can be used on chips manufactured by Intel, Qualcomm, and Texas Instruments while connecting to external devices like speakers, headphones, keyboards, mice, etc.

Who is affected?

Mentioned chips are used by many in a vast range of devices including big players with their products like Microsoft Surface laptops, Dell desktops, Samsung Phones, Google Pixel, and OnePlus handsets. The Bluetooth bug affects a wide range of devices, including smartphones, laptops as well as smart home gadgets. In total, more than one billion devices that rely on Bluetooth are believed to be impacted.

What is the damage?

The amount of damage possible with this flaw depends on the type of device with the chipset. Some devices can only be crashed after a specially crafted packet is sent to the flawed chip. If that's the case with your gadget, it can be easily resolved with a simple restart. With other devices, hackers can take advantage of the Bluetooth Classic flaw to remotely run malicious code. That could allow malware to be installed remotely. Researchers say vendors were informed about these issues months ago before the findings were published. The good news is this should have given plenty of time for the relevant patches to be pushed out that remedy the flaws. However, you'll need to make sure that you're running the latest version of the operating system to be protected by the patch crafted by the manufacturers.

Android Bluetooth threat

The researchers emphasize the lack of basic tests in Bluetooth certification to validate the security of Bluetooth Low Energy (BLE) devices. The BrakTooth family of vulnerabilities revisits and reasserts this issue in the case of the older, but yet heavily used Bluetooth classic (BR/EDR) protocol implementations. We would also advise users to disable Bluetooth on devices that do not need it. This way you can prevent attackers from sending you malformed LMP packets. Since BrakTooth is based on the Bluetooth Classic protocol, an adversary would have to be in the radio range of the target to execute the attacks. So, in a safe environment Bluetooth can be enabled.

5. After you’ve done this, reboot your computer and wait for the next startup to complete.
6. Open Windows Update once again and see if the installation of this pending update is now successful.

Installing the pending Update Manually

Whether you’re experiencing this issue with an integrated webcam driver or with anything else, chances are you’ll be able to circumvent the apparition of the 0x800705b3 error by using the Microsoft Update Catalog to find, download and install the pending update manually.

1. Open your default browser and navigate to the root web page of the Microsoft Update Catalog.
2. Once you’re inside the Microsoft Update Catalog, use the search function (top-right corner of the screen) to search for the update that is failing.
3. After the search is completed and you get the list of results, look for an updated driver version that is compatible with your Windows version and CPU architecture.
4. Once you manage to identify the correct Windows Update, click on the hyperlink associated with the update that you want to install, then click the Download button and wait for the process to complete.
5. After the download is complete, use File Explorer to navigate to the location where you previously downloaded the update.
6. When you get to the correct location, right-click on the .inf file and choose Install from the context menu that just appeared. Note: If you have multiple failing updates with the same 0x800705b3, repeat the instructions above with every Windows Update that you’re having trouble installing.
7. At the end of this operation, reboot your computer and see if the problem is fixed at the next computer startup.

Enabling the Windows Installer Service

The Windows installer service is responsible for installing pending updates that get downloaded by the Windows Update component. If this service is disabled on your configuration, none of the updates waiting to get installed will get completed.

1. Press ⊞ WINDOWS + R to open up a Run dialog box. Inside the text box, type ‘services.msc’ and press ENTER to open up the Services utility.
2. Once you’re inside the Services screen, move over to the right-hand tab of the screen, scroll down through the list of services and locate the Windows Installer service. When you find it, right-click on it and choose Properties from the context menu that just appeared.
3. Once you are inside the Properties screen of the Windows Installer services, access the General tab, click on the Start button to force-start the service. Note: If you can, also change the Startup type to Automatic via the associated drop-down menu. However, depending on your administrator settings, this might not be possible.
4. Restart your computer and wait for the next startup to complete. Once your PC boots back up, attempt to reinstall the driver that was previously triggering the 0x800705b3 error and see if the issue is now fixed.

Performing a Winsock Reset

In case the 0x800705b3 error is related to some kind of network inconsistency (TCP or IP related), you might see Windows Updates failing due to bad data that forces the Windows to abort the installation of new pending updates. In this case, you should proceed by doing a complete Winsock reset procedure to fix the majority of the socket and temporary data-related issues that might cause this behavior. Several affected users have confirmed that this method was the only thing that allowed them to finally fix the Windows Update issue and install pending updates normally. Here are some step-by-step instructions that will walk you through the process of performing Winsock Reset:

1. Open up a Run dialog box by pressing ⊞ WINDOWS + R. Inside the text box, type ‘cmd’, then press CTRL + SHIFT + ENTER to open up an elevated Command Prompt. Accessing an elevated CMD prompt Note: When prompted by the UAC (User Account Control) prompt, click Yes to grant admin access.
2. Inside the elevated CMD prompt, type and taste the following commands in order and press ENTER after each one to effectively reset the TCP and IP data that might be responsible for the apparition of the 0x800705b3 error code:

   nbtstat -R
   nbtstat -RR
   netsh int reset all
   netsh int ip reset
   netsh winsock reset

3. Once every command above is processed successfully, you can go ahead and close the elevated Command Prompt and reboot your computer.
4. After the next startup is complete, repeat the installation of the Windows Update that was previously failing and see if the issue is now fixed.

Performing SFC and DISM Scans

If none of the ‘superficial’ causes have worked in your case, you should start considering some type of system corruption that might affect your computer’s ability to complete pending updates that are currently waiting to be installed. In case you find yourself in this particular scenario, you should run a couple of built-in utilities capable of fixing corrupted instances that might be currently affecting the Windows Update component. Our recommendation is to start with a simple System File Checker scan. An SFC scan will cross-check every Windows File against a local archive that maintains healthy copies. In case corrupted instances are found, this utility will swap the corrupted instance with the healthy equivalent.

Performing an SFC scan

Once the SFC scan is complete, reboot your computer and wait for the next startup to complete. After your computer boots back up, initiate a DISM scan. This utility works differently in the sense that it relies on a sub-component of Windows Update to download healthy copies for the corrupted Windows files that need to be replaced. Because of this, it’s important to make sure that you have a reliable Internet connection before initiating this operation.

Doing a DISM scan

After the DISM scan is complete, reboot your computer one final time and see if the issue is fixed once the next startup is complete.

If you receive an error that says, “An unspecified error occurred during System Restore (0x800700b7)” when you tried to restore your Windows 10 PC, worry not, for this post will help you resolve the problem. This kind of error typically occurs when System Restore was not completed successfully and fails instead with this error. Before you start, you must not abruptly shut down your computer and wait for the error to occur. You may receive this error due to many possible reasons. It could be caused by your antivirus program that’s not letting the process complete or corrupted system files which causes the failure or it could also be caused by an unsuccessful installation of a Windows Update. Here are some fixes you can check out if you can still boot into your computer:

Option 1 – Try to disable your antivirus program

Disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the System Restore process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and then run System Restore again, don’t forget to enable the antivirus program back again.

Option 2 – Run the DISM tool

The next thing you can do is run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the blank dialog boxes. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the problem is now fixed.

Option 3 – Run the System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why you’re getting the errors 0x8024a11a and 0x8024a112. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Now restart your computer and see if the problem is fixed or not.

Option 4 – Try to run the System Restore in a Clean Boot State

If the first three given options didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run System Restore again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to run System Restore again and see if the process goes smoothly.

Option 5 – Run the Windows Update Troubleshooter

You might also want to run the Windows Update Troubleshooter as it could also help in fixing the problem with System Restore. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go. On the other hand, if you can’t boot into your Windows 10 computer, here are some fixes you can try instead:

Option 6 – Try running System Restore in Advanced Startup Options

If you cannot boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 7 – Run the SFC scan and DISM via Advanced Startup Options

Like what you did in the first given option, you can use the Advanced Startup Options to run both System File Checker and DISM. All you have to do is boot into the Advanced Startup Options and from there select Troubleshoot > Advanced Options > Command Prompt. After accessing Command Prompt, you can run the System File Checker scan first by entering the “sfc /scannow”. As for DISM, you can run the “Dism /Online /Cleanup-Image /RestoreHealth” command.

Option 8 – Try to run the Automatic Repair Utility

You might also want to use Automatic Repair in fixing the error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.

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.

3. 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.

4. Use DSIM or System Update Readiness Tool

The System Readiness Tool or DSIM is another method you can use to correct issues related to error code 0x80070490. This tool checks problems on your system that might prevent your computer from performing Windows updates including issues related to damaged system files.

Once you download and install this tool, it will be able to run automatically. The process may be technical, however, requiring specialized knowledge to successfully download and run the tool. Consider getting assistance from an IT professional in this case. Also, check Microsoft's online resources to download the tool.

5. Use an Automated Tool

Having an automated tool at hand will enable users to always be prepared. Download a powerful automated utility tool to provide solutions whenever error codes or other problems affect your Windows 8 device.
