A Quick Guide to Fixing Error 451

If you are trying to restore your computer using a System Image that has been created by the Windows Backup and Restore tool but encountered an error message instead that says, “Windows cannot find a system image on this computer”, you’ve come to the right place as this post will walk you through in fixing this error. Here’s the complete context of the error message:

“Windows cannot find a system image on this computer, Attach the backup hard disk or insert the final DVD from a backup set and click Retry. Alternatively, close this dialog for more options.”

In the error message, you are offered two choices – to either Retry or Cancel the operation. You can try to select Retry to try again but you will most likely get the same error if you do so. This kind of error can occur if the name of the WindowsImageBackup folder or any of its sub-folders has been modified. On the other hand, this error can also pop up if this folder or any of its sub-folders have gone missing or have become corrupted. To resolve the error, you can try to move the WindowsImageBackup folder or check its sub-folders. You can also try to isolate the System Image file or rename the System Image folder or remove all the unwanted sub-folders as well as use Command Prompt in Repair mode.

Option 1 – Try to move the WindowsImageBackup folder

The WindowsImageBackup folder must be stored in the root of the volume where it is stored, in line with the functioning of the System Restore utility. For example, if the WindowsImageBackup folder is stored in the “C:/Backups/System Restore Backups/New” location, then you have to move it to the C: drive as well.

Option 2 – Try to check the subfolders of the WindowsImageBackup folder

The classification of folders and files plays an important part to restore in restoring a computer from a System Restore point. Thus, if have modified the names of any files or folders inside the WindowsImageBackup folder, then you need to set the defaults. After that, run System Restore again and check if it fixes the error.

Option 3 – Try to isolate the System Image file

If the System Image file is stored in a USB storage device along with various System Restore images, then it’s no wonder why you’re getting this error. To set things right, you have to make sure that the System Restore image you wish to restore your computer from, is the only one that’s present at the root of the USB storage device.

Option 4 – Try renaming the System Image folder

If you have renamed the System Image folder prior to running System Restore, then it is most likely the reason why you’re getting the “Windows cannot find a system image on this computer” error. This error pops up because the System Restore utility in Windows 10 looks out for the WindowsImageBackup folder so if you have renamed it, you need to change its name back to what it originally was to fix the error.

Option 5 – Try to remove all the sub-folders of the WindowsImageBackup folder

If you have stored some foreign files inside the WindowsImageBackup folder, you need to get rid of them right away and return the folder to its default state as this folder must be left alone and should not be meddled with if you want to run System Restore smoothly.

Option 6 – Try to use Command Prompt in Repair Mode

• Open Command Prompt while your computer is in the Repair Mode.
• Next, type and enter this command where you need to replace “<Partition Letter>” with your drive’s letter: dir <Partition Letter>
• After you’ve found the WindowsImageBackup folder in any of the partitions, type and enter this command: dir <Parition Letter>WindowsImageBackup /s
• The command you entered will display all the contents of the folder exceeding 10 GB in total size. You can check and confirm the integrity of the folder and if you find that the integrity is violated, then it is the reason why you’re getting the error.

If you suddenly encounter an error message that says, “This webpage is not available, Err_Connection_Closed” while browsing the internet or visiting a website and the website fails to load, then it means that there is some problem with your network connection. Similarly, you may also get other error messages like “Err_Network_Changed”, “Err_Connection_Reset” and “Err_Internet_Disconnected” errors in different browsers like Chrome, Firefox, and Edge. The problem lies in your Windows 10 computer and your internet connection since this is a network issue. So before you troubleshoot the problem using the suggestions given below, you need to refresh your browser first or you could also tap Ctrl + F5 on your keyboard to hard reload the webpage. If you’re still getting the same error message, then proceed to the guide below.

Option 1 – Try removing the Proxy

Removing the Proxy might also help you in fixing the “This webpage is not available, Err_Connection_Closed” error. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try using Google Public DNS

If the first option didn’t resolve the issue, you can try to use the Public DNS by Google and see if it can help fix the problem. You have to modify the DNS settings in your system explicitly and use the DNS IP addresses.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 3 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the Err_Connection_Closed error. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 4 – Disable both the Antivirus program and Firewall temporarily

There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects which is why you have to disable these programs temporarily as it might be the reason why you’re getting the “This webpage is not available, Err_Connection_Closed” error when trying to browse the internet.

Option 5 – Try to check the network cables and then restart your router

The most obvious thing you can do first is to try checking if the network cables connected to your computer or router are properly connected or not. If it turns out that some network cables are not connected properly, then it’s probably why you’re getting this error.

Option 6 –Try a Network Reset

When all else fails, you might have to consider resetting your entire network settings. Simply follow the steps below to do so.

• Click on the Start button and then click on the gear-like icon for Settings to open it.
• Next, select Network and Internet.
• Then scroll down and look for “Network Reset” – click on it and then click on the Reset now button.

It is common to run multiple programs and applications at the same time and it’s important to be able to switch between them using their Taskbar icons or using the usual Alt + Tab shortcut. However, there are times when you might suddenly find that neither of the aforementioned methods worked and you will no longer be able to switch between programs in the Windows Taskbar. To fix this issue, refer to the options given in this post. For instance, when you have multiple instances of Microsoft Edge running and every time you press the Alt + Tab combo nothing happens so you are left with no choice but to minimize everything and then hover your mouse on the icon and switch between the instances of Edge. You will also notice that the right-click on the taskbar won’t respond back and will only keep on showing the loading circle icon. Here are a few tips you can follow to fix the issue with the Windows 10 Taskbar.

Option 1 – Try to restart the Windows Explorer

This is one of the basic things you can try as restarting Windows Explorer helps in refreshing the user interface and makes most of the things work in relation to the user interface.

• To get started, tap the Alt + Ctrl + Del keys to pull up the Windows Task Manager.
• After opening Task Manager, look for “explorer.exe” under the list of programs.
• Once you find the explorer.exe, right-click on it and click Restart.

Option 2 – Try changing the Foreground Lock Time

Aside from restarting Windows Explorer, you could also try changing the Foreground Lock Time to fix the issue with the Taskbar.

• Tap the Win + R keys to open the Run dialog box.
• Then type in regedit in the field and tap Enter to open the Registry Editor.
• Next, go to this registry key – HKEY_CURRENT_USERControl PanelDesktop
• Next, change the ForegroundLockTimeout value from200000 to 0. After that, it will make sure that no other application will take away the focus from your current program or application. It could be that some other application has taken away the focus and even when you try to actually switch, the focus gets back to the old one. Anyhow, since you already changed the value of ForegroundLockTimeout, it will ensure that the focus is not switched.

Note: If you are running some Full-Screen applications there are some devices especially the gaming ones, disable the Windows key to make sure that you won’t be able to switch. If this is the case, you need to make some modifications to the Full-Screen games.

Recently, several Windows 10 users have reported an issue with the Windows folder sizes in their PCs. If you are one of these affected users, read on as this post will walk you through fixing this issue. For instance, if you have a folder with 100 GB worth of data and when checking its size using its properties, you see the wrong size instead of 100GB. The size displayed will most likely be a random number which can either be bigger or smaller than the real size of the folder. This incorrect folder size issue does not happen to any specific drive or certain kinds of folders as any folder can be affected by this incorrect folder size issue. When you try to rename the affected folder, the size will change but its size still remains to be incorrect. The root cause of this particular issue is in Windows 10 itself. It is a known bug that came along with one of the latest Windows Updates which prevents the File Explorer to accurately read the metadata of a certain folder or file and leads to displaying incorrect and unexpected file sizes and the reason why you might also notice that your drive is also not correct. Since this is brought upon by one of the recent or latest Windows Updates the good thing is that Microsoft will most likely release a fix on its next upcoming updates but until then, you will be left with no choice but to deal with an incorrect folder or file size. To remedy that, here are some suggestions you can try that might fix the problem.

Option 1 – Try using the System File Checker

The 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 causing the incorrect folder or file size in Windows 10. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• 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.

Option 2 – Try resetting Windows 10

To fix the folder and file size issue, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files. That way, you won’t have to deal with inaccurate folders or file sizes as you browse and use your files.

Option 3 – Wait for the Windows Update

As mentioned, this is already a known issue and a lot of Windows 10 users have already complained about it to Microsoft so a bug fix will be soon released in the latest Windows Updates.

Corsair is well known for RAM memory modules for PC but then it has expanded to PC peripherals and even selling some pre-build computers as well in past few years. New Corsair expansion now includes a laptop line, starting with their new gaming laptop Voyager.

Voyager laptop is packed with a mechanical keyboard and MacBook-like touch bar for your typing and pointing needs. It is built with a 16-inch QHD+ screen packing 240Hz that is run by Radeon 6800M GPU. Also inside lurks AMD 16 thread Ryzen 9 6900HS CPU, Wi-Fi 6E support, Dolby Atmos audio, and full HD 1080p WEB camera.

The keyboard has low-profile mechanical Cherry MX switches with per-key RGB lightning and above is what Corsair calls a macro bar, with 10 shortcut buttons and a small LCD in the center.

Corsair is also including a few features that tie in with its other products. Many of the company’s keyboards, mice, and other accessories use the ‘Slipstream’ USB wireless adapter, which is built into the Voyager laptop. The macro bar is also configured using the same software used for the Elgato Stream Deck, a popular product sold by Corsair.

If Error Code 0xc00000e9 appears on your screen, there is no cause to panic yet as there are different ways to fix this. Here, I will list down different methods to get your computer back on track:

1. Check peripheral connections
2. Check your SATA cables
3. Check your hard drive
4. Check your BIOS settings

Quick Fix 1. Check Peripheral Connections

1. Turn off your computer.
2. After the computer has been shut down, take off all the peripherals or the USB cables that are connected to your USB ports. This includes even the keyboard and the mouse. We just need to have only the monitor plugged in for this one.
3. Turn on your computer and see if it starts as it normally does.
4. If it does, try connecting back your external devices or peripherals one by one until you find the one that causes the error.
5. Once you trace the device that’s causing the error, you will have to change its USB cable and update its driver to support your operating system.

Quick Fix 2. Check your SATA cables

It is possible that what causes a barrier between your operating system and your hard drive from communicating is the SATA cable used. For example, if you’re using an older SATA with a SATA III port, there might not be adequate support for the transfer of data from one another. Or, the problem might be a loose SATA cable which would still require you to buy a new one to replace your loose or damaged cable. To check if your SATA cables are causing the error, simply follow these steps:

1. Turn off your computer.
2. Carefully open its case.
3. Check the hard drive and the SATA port where it’s connected.
4. Try to use a newer cable and connect it to your SATA port. (If you used a SATA II cable, you can see if a SATA III cable is more compatible.)
5. Replace your SATA cable with a newer one if Step 4 proves to be successful.

Quick Fix 3. Check your hard drive.

1. Try to use a different hard drive and see if error code 0xc00000e9 still appears.
2. If it works out just fine, then the problem might be physical damage to your hard drive and would need to be repaired depending on the case. Just simply take it to a technician and let him know about the issue.

Quick Fix 4. Check your BIOS settings

1. Restart your computer.
2. Once your computer starts, press and hold the ESC, F2, F12, or DEL key to go to BIOS settings.
3. You will then be redirected to the BIOS Setup Utility screen. From here, go to Boot options.
4. In the Boot Options, see if your first boot device is your hard drive. If it isn’t, press the arrow key to select the hard drive and move it to the top of the boot device list.
5. Save the settings.
6. Reboot your computer.

Note: If all the methods above do not work, the problem might be on your drivers and you might need to update them. You can update your driver in two ways: Manual driver update and Automatic driver update. You can find procedures online in updating your drivers.

What is OpenCandy?

OpenCandy is an application that downloads and installs software, including other Internet Browsers to a computer system. Used as a bundle, this application installs additional programs that you may knowingly or unknowingly agree to install. Since most users don’t accept the challenge of reading the EULA in its entirety, they tend to download bundled applications unknowingly.

Assessment of OpenCandy PUP

During the initial assessment of OpenCandy, I was a little skeptical about what to look out for or expect. In fact, I had to install the OpenCandy.exe file twice to discern its behavior. I’m not sure how this application got its name but I do believe it has something to do with the fact that it supposedly helps Internet users open a new world of Internet browsing. That conclusion was arrived at after realizing that OpenCandy.exe installed mostly Internet browsers along with a tune-up tool on the test computer. However, as a result of the system requirements, there was a pop-up message indicating that Internet Explorer 8 was not compatible with the computer system in question. In comparison to the malware I’ve encountered since I started researching malware, OpenCandy is everything but malicious. In fact, this application is only categorized as malware because of its’ subtle covert nature of installing bundled programs unsolicited by the user. Additionally, OpenCandy coerces users into changing their Internet Browsers by installing those unrequested by the user. In fact, it’s no shock that OpenCandy chose to install the Internet Browser ‘Opera’ as a part of this bundle since it’s one of the least used browsers according to the Federal Government. Clearly, this was a smoothly disguised advertisement or promotion to force users into using the Opera Browser, along with Internet Explorer 8.0. While these aforementioned browsers in themselves aren’t malicious and are in no way considered malware, they were installed as a promotional tool and without the request of the user. Despite being mentioned within the EULA, advertisers are capitalizing on this since most users do not bother to read the agreements when installing a program. Furthermore, OpenCandy, like most other bundled applications I’ve dealt with, threw in a tune-up tool as a part of the promotion. I found this tune-up application annoying since I had to hassle my way into getting it to close from the computer screen. I can only imagine the hassle users would go through trying to remove this software. Image 7: Depiction of a scan performed by Tuneup Utilities. The scan detected that several areas on the test PC could be optimized/tuned up. Image 8: After a scan was completed using the Tuneup utility program, I was given an option to buy the full version. Nothing is wrong with this marketing strategy. In fact, most utility tools if not all will scan your computer to detect threats or loopholes, but they won't exactly allow you to fix those problems unless you buy the full version. It's not unfair, it's just business. Programs installed during the installation of OpenCandy include:

• Web Companion: Developed by Lavasoft, Web Companion is said to be an application that serves as a security defense for your Internet browsers by preventing unauthorized changes (see image below)
• Tuneup Utilities: Tuneup Utilities does exactly as it says. It cleans up a computer system, whereby preventing unused programs from slowing it down.
• Opera Stable 30.01.1835.88: Opera is a fast, simple, and effective Internet browser that allows users to get around on the web.

All in all, the intent of installing an application such as OpenCandy is to unleash a world of promotion or advertisements on your computer. They are pretty annoying and in some cases difficult to remove. Furthermore, as a user, you want to control what gets installed on your computer without being dictated to or coerced in some EULA that you probably overlook.
