A lot of things can go wrong even when you’re only doing some simple operations or tasks on your computer and this is due to the fact that there are various small operations make up in order to perform the larger operations on your computer. So if any of these smaller operations are not properly working, it crashes the operation as a whole and it throws an error code instead. And one of these error codes is Error 0x800701e3. This particular error pops up when an error has occurred in the File Explorer when a transfer is initiated from one disk to another in your Windows 10 computer. When you encounter this error, you will get the following error message:

“Error 0x800701e3: The request failed due to a fatal hardware error.”

There are several methods you can check out to fix this error – you can try to run System Restore or Check Disk or format the destination drive or check the SMART attribute of the drive. For more details, refer to each one of the following options.

Option 1 – Try to run System Restore

Error 0x800701e3 might be due to some adjustments you’ve made in your computer’s settings. Thus, to fix this error, you can try undoing those changes using System Restore. How? Refer to these steps:

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and then check if your mouse is now back to its normal state.

Option 2 – Try running the Check Disk utility

You can also run the Check Disk utility in fixing Error 0x800701e3.

• In the Windows Search box, type “command prompt” and from the search results, right-click on Command Prompt and select “Run as administrator”.
• After opening Command Prompt, type this command and tap Enter: chkdsk <Partition Letter>: /f /r /x /b
• The command you entered will start to check for errors and fix them automatically. Else, it will throw an error message saying, “Chkdsk cannot run because the volume is in use by another process. Would you like the schedule this volume to be checked the next time the system restarts? (Y/N)”.
• Tap the Y key to schedule Disk Check the next time your computer restarts.

Option 3 – Try to format the destination drive

Formatting the destination drive could also help you resolve error 0x800701e3. To format your drive, follow these steps:

• First, open File Explorer and then right-click on the drive where you encountered the error.
• Next, select Format from the context menu. This will open a new mini window.
• Then select the NTFS option from the drop-down menu for the File System menu.
• After that, check the box labeled as Quick Format.
• Now click on Start. Keep in mind that doing so will remove all the contents of your storage device.

Option 4 – Verify the hard drive using SMART attributes

In case you don’t know, Windows has a built-in feature of SMART analysis which analyzes the hard drive/SSD and checks all the parameters by performing some minor operations. To use it, follow these steps:

• Tap the Win + S keys and type “command prompt” in the field then right-click on the related search result and select the “Run as administrator” option.
• After opening Command Prompt as admin, type the “wmic diskdrive get status” command and hit Enter.
• You should get a result after that, and if you see that it’s “normal”, proceed to the next option below

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.

There is a central location in Windows 10 that allows users to view all the notifications from its Action Center. Aside from viewing notifications, users can also manage them and take necessary actions in just one single place. Notifications in Windows 10 look similar to a message icon but can be at variance in function. However, recently, a number of users reported that even though they receive notifications about new actions but when opening them, they see nothing. In other words, the notification is false, and to fix this, read on as this post will provide you a couple of workarounds. The Windows 10 Notifications and Action Center notification messages might show a mismatch. For instance, Windows 10 may say that you have some notifications but when you open Action Center, you find it empty and there are actually no notifications there. Take the case of the following screenshot, the Windows 10 Notification says that there are 6 new notifications available for viewing but the Action Center says otherwise. Before you troubleshoot the problem, you might want to run System Restore especially if you’ve made some changes in your computer prior to this issue which might have messed with the Windows 10 Notifications and Action Center. To perform System Restore, refer to these steps:

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

If the problem wasn’t fixed and you’re still getting false notifications, you might want to troubleshoot the problem further using the options given below.

Option 1 – via Windows PowerShell

• In the Start search, type “PowerShell” in the field and hit Enter to pull up the Windows PowerShell window.
• Next, copy and paste this command and hit Enter to execute it: Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppxManifest.xml” -verbose }
• After that, reboot your computer and check if the false notifications are now gone.

Option 2 – Try renaming the Usrclass.dat file

DAT errors like the ones that are associated with the Usrclass.dat file, most likely occur during computer startup, program startup, or while you try to use a specific function in your program. Even so, it can easily be fixed. How? Refer to the given steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type %localappdata%MicrosoftWindows and hit Enter to get to the location of the UsrClass.dat file.
• After that, look for a file named UsrClass.dat and once you’ve found it, right-click on it and select the Rename option.
• Now rename the file to UsrClass.old.dat and then restart your computer and see if the problem is now fixed or not.

Default applications in previous Windows versions were a pretty straightforward process. The user went to the settings application and picked for each category which application he would like to choose from the list of installed ones. In Windows 11 things are little changed. In this article, we will show you how to choose the default internet browser inside Windows 11, and sadly it is a more tedious task than in previous versions.

Choosing default browser in settings

As in previous versions of the Windows operating system you will need to use the settings application in order to change your default Internet browser. Previously, in Windows 10, a variety of general categories like email, web browser, and photo viewer were all listed under the Default Apps section of the Settings panel. It was easy to click on one of those categories and click on the option you like best from the small pop-up suggestion window. In the Windows 11 Insider Build, you’ll see a gauche list of an individual file or link types that you’ll need to specify your preferred browser for. The types include: HTM, HTML, PDF, SHTML, SVG, WEBP, SHT, FTP, HTTP, and HTTPS. There are additional optional types you can specify your preferred browser for as well. The issue here is in order to use a single browser which most users do you will have to go through each file type and set your preferred one. I am really not sure why this was introduced or why it has to be this way, all I can do is hope that in the final release of Windows 11 this feature will be rolled back as it used to be and that you could set your default browser in just one simple click.

Windows photo viewer was a popular photo viewing application integrated into Windows 7, 8, and 8.1 but in Windows 10 it has been replaced with photos, Microsoft's new application aimed at photo viewing on your desktop. Now if any one of you wonders why should be bringing the old application back to Windows 10 since we have an alternative one, the answer would be resources and speed. The old photo viewer application is lightweight, fast, and reliable, opening the same photo in both photo viewer and in new photos shows us that Microsofts new viewer application takes even three times more RAM, and it's visibly slower in loading times for pictures. Since I am a person who prefers speed and functionality over fancy looks I would be very glad to have the option to bring back a photo viewer. If you have by any chance Windows 10 as an upgrade, bringing back photo viewer is easy as 1,2,3. you just need to open settings and go to default apps, under photo viewer you should see your current default viewing application, probably photos, click on it to see options and choose photo viewer and exit the Settings menu, and you're done. Sadly if Windows 10 has been installed clean on the system and not as upgrade things are a little bit more complicated but do not worry, stay with us, keep reading and you will get there.

Activating photo viewer

How technically photo viewer is still in the system but not used we will have to make it available again and this we will do by adding some lines in the Windows registry, that being said, open a notepad and paste the following code as it is in it.

Yup, that is a lot of keys and settings but you are almost done. Once you have pasted text into your new notepad document save it but as .REG, you can name it however you want but it has to be .REG extension. Once the file is saved double click on it to merge it into the Windows registry. You might need to turn off UAC for this operation (check our tutorial on this topic) and accept warning messages but once it is done you should now have an old photo viewer as a choice for your default viewing application. All you have to do now is to go to settings and go to default apps, under photo viewer you should see your current default viewing application, probably photos, click on it to see options and choose photo viewer and exit the Settings menu, and you're done.

If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• SYSTEM THREAD EXCEPTION NOT HANDLED
• IRQL NOT LESS OR EQUAL
• KERNEL DATA INPAGE
• SYSTEM SERVICE EXCEPTION

To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named ACPI.sys and rename it to ACPI.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the ACPI.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is 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.

• Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
• After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.

• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.
