USB storage devices are used to store small and even big files, depending on their sizes. Usually, the sizes of the USB vary from 2GB up to 16GB. And as time passes, they have advanced quite a bit and now it’s common to find USB sticks with a capacity of 32GB, 64GB, or even 128GB. And since they now have large capacities, USB storage devices are often used for storing backups of system data as well as creating an image. However, there are times when you might encounter an error message while trying to create a backup or image on your USB device. The error message states:

“The drive is not a valid backup location.”

One of the causes of this problem is that Windows was not able to recognize the USB drives as a valid backup location since USB storage devices weren’t previously large enough to store system images. To fix this error, here are some possible solutions that might help.

Option 1 – Try creating a sub-folder in the USB drive and backup all the images there

The first thing you can try to do is to create a sub-folder on your USB device. This is one good way you can bypass the USB drive limitation. How? Refer to the steps below.

• First, right-click on the USB storage device and select Format.
• Next, select NTFS as the File System and check the box next to Quick Format.
• After that, click on Start to initiate the formatting process.
• Once the formatting process is completed, open the USB drive and right-click anywhere inside its main drive window, and then select New > Folder.
• Then name the folder to be created as “Image (or anything you please)”.
• Afterward, right-click on the folder and select Properties.
• From there, go to the Sharing tab and click on Share.
• Now check if the Permission level on the System owner which should be your username is labeled as “Owner”.
• Then try to back up your files again using your USB drive while keeping the sub-folder as the backup location.

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 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Error Code 0x80072EE2 – What is it?

Windows 10 error code 0x80072EE2 usually occurs as a result of a disruption during the upgrade process when users attempt to upgrade their operating system using Windows Update.

Error Causes

Upgrade error codes like error code 0x80072EE2 usually occur when disruptions or problems related to system files, or third-party apps prevent Windows Update from completing an upgrade. In the case of error code 0x80072EE2, the most likely cause is a bad Internet connection.

Further Information and Manual Repair

Windows 10 error codes are numerous and so are the solutions to fixing these problems. In most cases, Windows users have access to several manual repair solutions depending on the error code present on their device. These manual repair methods are usually easy to implement, with the exception of a few solutions that require technical knowledge and skills. In such cases, you may need to consider using an effective automated tool or you may contact a Windows repair technician to assist you.

In terms of error code 0x80072EE2, however, no technical skills are required. Manual repair solutions for this error code involve checking and troubleshoot network problems if your connection was disrupted. Also, you may need to check your firewall settings and disable it temporarily to verify whether or not your firewall is preventing you from accessing the upgrade. Further details are provided below.

Method One: Verify Internet Connection

If for whatever reason you lost Internet connection while attempting to upgrade your operating system via Windows Update, your upgrade will time out and error code 0x80072EE2 in Windows 10 may occur. For this reason, it is important for you to check your connection once you notice the presence of error code 0x80072EE2 on your device.

There are many ways you can verify your Internet connection but one of the simplest ways is to first open your preferred Internet browser and type the web address of a site you normally visit. Once you are able to access the website, you will know for sure that your connection is not an issue. Simply restart your PC and reattempt the upgrade.

If you are unable to complete the upgrade process, however, this simply means that there is another issue causing error code 0x80072EE2 to occur. Proceed to the next manual repair method. This method may also apply if you were unable to connect to the Internet.

Method Two: Troubleshoot Network Problems

Though you may be able to access a website or open your Internet browser, there may be other issues affecting your network that are causing the error code to occur. To verify for certain whether or not the issue causing error code 0x80072EE2 in Windows 10 is related to your network, troubleshoot your network using the Network Troubleshooter tool found on your PC.

• Step one: Type Network Troubleshooter in the search box near the Start button
• Step two: Select Identify and repair network problems
• Step three: Wait until the troubleshooter has verified and fixed problems related to the network
• Step four: Restart PC

Once the issue has been resolved, it is time to verify if the error code is fixed. Open Windows Update then select the option which enables you to access the latest upgrades to your machine. Wait to see if the error code reoccurs or if you can now access the upgrade to your operating system. If the error code reoccurs, move to the next manual repair method.

Method Three: Disable Firewall Settings

Another issue that may be causing an error code to occur is your firewall. To verify if your firewall is preventing you from accessing the upgrade, disable your firewall. If you are using third-party security software, simply open the security app and check its firewall settings. Select disable or turn off the firewall.

Restart your computer, then open Windows Update to reattempt to upgrade your device. If this proves successful, you will be able to access the upgrade. Error code 0x80072EE2 in Windows 10 will no longer be present.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

What is AppCrash Error?

As the name implies the AppCrash error is an error code that indicates a crashed program/application on your system. This term is used by Windows to designate an application crash. It is reported and displayed on the system as “Problem Event Name: AppCrash,” which is followed by additional technical information which unless you are a computer programmer, you may not fully decode. There are various symptoms that trigger the occurrence of this error code on your system such as:

• Application becoming unresponsive and intermittent
• Momentary application freezing
• Application times out and then successfully recovers itself

Solution

Error Causes

The reason for AppCrash error occurrence cannot be narrowed down to a specific cause. This error code is triggered by multiple causes such as:

Black Screen During Installation - What Is It?

Many are upgrading their OS to Windows 10, however, it’s not always smooth sailing because users have been reportedly experiencing different bugs including Black Screen after a successful update.

One common issue in installing Windows 10 is the appearance of a black screen after installation. This usually occurs when the user restarts the computer. Initially, there will be a black screen only appearing on the monitor. There are also cases where a mouse cursor is present, while some cases have no cursor at all.

Not only that, it seemed that you’ve lost all your desktop icons when experiencing this bug.

Solution

Error Causes

Just like the other bugs experienced by Windows 10 users, booting to a black screen has reasons. Before you even try to look for the solution, you first have to determine the cause of the error, in this case, the error would be black screen when booting.

• Error on external devices such as printer or mouse.
• Having outdated display/video drivers that normally result in black screen when OS is updated.

If error messages are left unsolved, you may encounter other Windows 10 related issues such as error code 0xc0000142. 

Further Information and Manual Repair

Before you even think of upgrading your OS to Windows 10, you need to know that there are specific system requirements and specifications to be able to successfully update your operating system.

• Minimum of 1 gigahertz (GHz) Processor
• Either 1 (GB) (32-bit) or 2 GB (64-bit) Ram
• You need at least 16 GB of free hard disk space
• A Microsoft DirectX 9 graphics device or later with WDDM 1.0 driver graphics card
• 800 x 600 display
• A Microsoft account and Internet access.

There are more system requirements in order to use other certain Windows 10 features, but we’ll focus on solving your black screen problem in this article.

IMPORTANT NOTE: While it’s possible that you’ll be able to find the solution for your black screen during Windows 10 update, contacting the service of a professional technician or using an automated tool is advisable if you’re not confident in performing the methods to be discussed.

Method 1: Windows 10 DVD Boot

1. Hit Repair your computer at the Install Now screen.
2. Press Advanced Options
3. When you’re in the Advanced Options find Troubleshoot and click it.

4. Click Safe Mode option

There’s a chance that you’ll get an error prompt saying, “installation cannot be completed in safe mode.” If this happens, simply press Shift + F10. This command will redirect you to the Command Prompt. You just open Device Manager by keying in devmgmt.msc then disable the display adapters, now check if you’ll be able to successfully boot in normal mode.

This process will normally allow you to complete the Windows 10 installation, if that’s the case you can just update the display adapter drivers from the manufacturer’s website. Restart your computer and see if this solves the problem.

Method 3: Driver Roll Back

1. Hit Windows Key + X then press the Device Manager
2. Expand the Display Adapters option
3. Right-click the listed Display Adapter and press on properties
4. Find the Driver Tab and click on it, then press Roll Back Driver

Do take note, however, that the Roll Back Driver option is not available if there was no previous version installed.

Method 4: Check External Devices

Since one common cause of black screen during a Windows 10 update is the external devices you use in your computer, you might want to consider these steps as well.

1. Simply unplug all of the external devices you currently use
2. Restart your computer
3. If in case this solved your black screen problem, carefully plug back the devices one at a time to determine which of the device is the culprit.
4. Update the drivers for the outdated hardware using a reliable third party tool.

Method 5: Fast Startup Disabled

Some Windows 10 users had success in solving their black screen problem by disabling the fast startup.

1. Go to the Control Panel, find Power Options and press “Choose what the power button does,” which is located in the left pane of the panel.
2. Hit the “Change settings that are currently unavailable.”
3. Make sure to unmark the checkbox button saying, “Turn on fast startup.”

What is Webguard?

Developed by Interesting Solutions, Webguard is a tool supposedly used for tracking those online who’ve developed a habit of tracking you. The application would provide logical analysis into a user’s website history, providing insight on what websites you’ve visited and also how persons are able to track your every move while browsing. While Webguard is unable to dispose of who specifically is tracking your computer usage, they’re able to determine what computer installed tracking codes or cookies on your computer system. In this case, it’s then left up to the user’s discretion to determine who they want to allow or block from tracking their online use.  Overall, this application allows the user some measure of freedom and control over their online experience. Like any other application, however, which has landed themselves a spot on Virus Total, Web guard has hidden agendas. At a distance, Webguard installs a service for Windows but later distributes advertisements. Technical details about Webguard include:

Product Version: 1.0.0.0 Original File Name: crss.exe Entry Point:  0x000C5AAE

Assessment of Webguard Potentially Unwanted Program

While Webguard claims to track your computer usage, information reported by the application isn’t sufficient for the common computer user. This brings us back to the ulterior motive or principal objective of developing Webguard – to advertise and generate revenue from clicks made by users on Ads displayed on Internet Browsers – namely Chrome, Internet Explorer and Firefox. Why should a computer user remove Webguard? Simply, it compromises one's Internet privacy and security and it keeps abreast of your Internet history. If you’re online for an extended period, you’ll see what Webguard does. While the publishers behind the application did not alert users to the use of web beacons, cookies for tracking, and other related tracking technology, that’s not why Webguard is considered unwanted. The program is potentially unwanted because of the unpredictable advertisements it displays. Not all sites are trusted and so it’s difficult to determine, in some cases, what websites are legit for business.

Remove Webguard with Spyhunter

In most cases, at least from what I’ve seen, Webguard is installed as a single application. After it was installed for this assessment, it could be found in ‘All Programs”. This meant that one could manually delete the application from their computer system (see manual steps below). However, is that really sufficient to completely rid your PC of Webguard’s blueprints? While you might opt to remove Webguard manually – maybe because it’s more economical – an automated process is able to completely eradicate hidden threats from Webguard. In comparison to manually removing Webguard, Spyhunter penetrates your computer system for all infections. In most cases, nasty threats are unable to be removed manually. Additionally, Spyhunter not only removes installed threats, but it detects incoming ones – hence, acting as a preventative tool. Furthermore, Spyhunter detects cookies placed on your computer by Webguard. These are all undetectable threats and so an automated tool, as Spyhunter, should be used to remove Spyhunter effectively from your computer.

Manual Steps for Removal of Webguard

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:

• Step 1: Locate the CONTROL PANEL on your computer using the SEARCH option.
• Step 2: Once the search box appears , input 'CONTROL PANEL'.
• Step 3: The Control Panel option will then appear. From the menu, choose the "Programs" option.
• Step 4: Another menu will appear. Select "All Programs and Features".
• Step 5: From the 'Programs list', search for the Webguard application.
• Step 6: Right-click on Webguard when it's found.
• Step 7:  Choose the "Uninstall" option.
• Step 8:  Follow the uninstall wizard instructions until the Webguard application is fully removed.
