Why Can’t drag and drop files or folders happens? In case you don’t know, there is a feature in Windows 10 called drag and drop that can help you move or copy files or even folders from one location to another. This feature is useful and can help you move or copy folders and files easier and quicker. However, if you encounter some problem while using this feature, worry not for this post will guide you on what you can do to resolve the problem. There are several suggestions you can check out to fix the problem. You can try to simply tap the Esc key or you could also troubleshoot the problem in a Clean Boot State. Aside from that, changing the drag height and width or disabling the User Account Control via Registry Editor might also help. For more details, refer to the instructions laid out below.

Option 1 – Try to tap the Esc key

According to some users who experienced the same dilemma, by simply tapping the Esc key, they were able to resolve the problem. All they did was tap the Esc key before they drag and drop the folder or files. Thus, you can try doing the same thing as it might also work for you. After you tap the Esc key, you have to check all the background applications and if you see some that could be related to the hotkeys or keyboard, you might have to disable or remove them. Once done, check if the problem is fixed or not.

Option 2 – Try troubleshooting the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the reason why you’re having trouble using the drag and drop feature in Windows 10. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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” checkbox 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 to configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 3 – Try changing the drag height and width

The next thing you can do to resolve the issue is to try changing drag height and width by following these steps:

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry key: HKEY_CURRENT_USERControl PanelDesktop
• From there, choose to modify both the “DragHeight” and “DragWidth” located on the right pane.
• After that, change the value to a very high number. Note that these values are nothing but pixel size to drag and drop folders or files.

Option 4 – Try disabling the User Account Control or UAC via Registry Editor

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem

If you were trying to install a program on your Windows 10 computer but encounter an error instead that says, “Error 1310, Error writing to file: <PATH>, Verify that you have access to that directory” then read on as this post will guide you on how you can fix it. This kind is a fairly common type of error encountered by many Windows users. You can get this error when you try to install certain programs like Excel, AutoCAD, Adobe Photoshop, and some other Adobe products on Windows. One of the most likely causes for this error is that the required files or location is already used by some other software which means that Windows finds that you are trying to overwrite a software that is already installed. Aside from that, it could also occur if the program installer does not have access to write to that directory. To fix Error 1310, here are some potential fixes that could help.

Option 1 – Clear up temporary or junk files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.

Option 2 – Reinstall the program in a Clean Boot State

You can also troubleshoot Error 1310 in a Clean Boot state. It could be that there are some third-party applications in your computer that's preventing the program from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• 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.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the program again.

Option 3 – Try to unregister and re-register the Windows Installer Module

• Tap the Win + R keys to open the Run dialog box.
• Then type the “msiexec /unregister” command and hit Enter to unregister the Windows Installer Module.
• Next, type the “msiexec /regserver” command and hit Enter to re-register the Windows Installer Module.
• Now restart your computer and see if un-registering and re-registering the Windows Installer Module fixed the problem or not.

Option 4 – Take ownership of the location where you want to install the app

The next thing you can try to do is to take ownership of the particular folder as this worked for some users who experienced the same problem. But before you do that, you have to create a System Restore Point first, once that’s done, proceed to the given steps below.

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.
• Finally, try to install the application again.

If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem. When you encounter this kind of problem on your computer, you will get the following error message on your screen:

“Secure Boot Violation The system found unauthorized changes on the firmware, operating system, or UEFI drivers. Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed. Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”

This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try running System Restore in Advanced Startup Options

Since you probably can’t 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 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

In today's age, free cloud storage is no longer anything exclusive and plenty of companies will offer some free amount of it in hopes that you will buy a premium plan. Among plenty of starter and free options, there are of course some that are more generous and more appealing and offer a larger quantity of free space and even some other services.

In this article, we are taking a look and recommending some of the best ones in our opinion.

Google drive

First on the list is of course google with its google drive. With an amazing 15GB of free could storage just given to anyone who makes a google account this had to be the first recommendation. Also since google drive is requiring a google account you will be given all google office tools for free as well as the Gmail service. Completely free 15GB at your fingertips if you do not mind google tracking policies.

Microsoft one drive

Another company on the list, with only 5GB storage seems little compared to google this entry was simply included because google Microsoft also offers you Office 365 WEB for free with skype along with their Hotmail. So all in all another full package of apps with some free storage that requires also just an account.

IceDrive

With the free offer of 10GB this comes as an easy recommendation, IceDrive is a cloud storage company that is not offering anything of productivity apps but it has some great features in their cloud solution like being able to see encrypted files in your cloud. All you have to do to get this 10GB of storage is to make a free account.

MEGA

With an amazing 20GB of free storage, MEGA is certainly one that gives the most space for free. Sadly a few years ago it was hacked and files and user information were leaked, for that reason, it is on our last place of recommendation but if you are not worried about their security and plan just to use this as a temporary file sharing service with that amount I am sure it will fill your needs.

It can cause updates to fail, which can often be frustrating for Windows users who are attempting to keep their devices up to speed.

Common symptoms include:

• Failure of updates for the Windows operating system to complete or download
• The appearance of an error message that references the number 0x80244019

While an error during the Update process can be frustrating to encounter, there are a few simple solutions that can be employed to try to address the problem at hand. At least one of the methods for resolution does require some familiarity with the command prompt and other advanced tools, so if you are not completely confident in your ability to follow the steps mentioned below, you may want to get in touch with a qualified repair technician who can assist you in resolving the error code.

Solution

Error Causes

In some cases, the error in the Update process can be caused by a conflict between the operating system and the antivirus software running on your computer. In other cases, there may be a portion of the file missing or corrupted that needs to be fixed before the Update process can be run through to completion.

Further Information and Manual Repair

For users who are experiencing the appearance of Error Code 0x80244019 on their devices, there are a few methods that can be used to attempt to resolve the issue. While at least one of these methods is fairly simple to complete, even for basic users, the other does require some comfort in using the command prompt to input a series of commands. If you do not feel comfortable in following the steps listed below, contact a computer repair professional who is familiar with Windows 10 to assist you.

Here are the top methods for dealing with Error Code 0x80244019 on a Windows machine:

  • Net stop bits
  • Net stop msiserver
  • Ren C:\Windows\Software\Distribution Software\Distribution.old
  • Ren c:\Windows\System32\catroot2\Catroot2.old
  • Net start wuauserv
  • Net start cryptSvc
  • Net start bits
  • Net start msiserver
• Step Three: Type in the word “exit” to quit out from the Command Prompt.

Once these steps are done, you can try to use the Windows Update tool again to see if the problem has successfully been resolved.

Method Three: Use 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.

One of the most useful utilities for advanced users in Windows is the Windows command line or Command Prompt. It is efficient in fixing system files, checking the disk for errors as well as other intensive tasks that are made convenient using this. One of the tasks you can carry out using Command Prompt is repairing the Windows bootup process if it encounters any issues. However, if you tried running the “bootrec/fixboot” command and you receive an error message saying, “Element not found”, read on as this post will guide you in fixing this error. This kind of error in the command line could be due to a damaged BCD or MBE, inactive system partition, or it could also be that there is no drive letter being assigned to the EFI partition. Whichever the case is, here are some possible fixes that should help you resolve the problem.

Option 1 – Try to repair BCD

As mentioned the error could be caused by a damaged BCD and so to fix the problem, you need to repair BCD by following these steps:

list volume

• Now type the following command to select the desired volume:

select volume number

• Then type the following command to assign a letter to the selected volume:

assign letter=<LETTER>

Note: Make sure to replace “<LETTER>” with the letter you want to allocate to that partition. Afterward, it will assign a letter to the selected volume.

• Reboot your PC to apply the changes made.

Option 3 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

Method Two

Activate by phone- this is a much simpler method.

1. Click on Start, type: slui.exe 4 into the Search box
2. Press Enter on the keyboard.
3. Pick your country.
4. Choose the Phone Activation option; stay on hold to speak with a customer service representative.

Method Three

Error code 0xC004C020 occurs if you have used your Windows 7 activation key on multiple computers, or multiple times on the same computer. You are not allowed to exceed the uses of the key—you should consider purchasing a new key if this is the case. A Windows 7 key is available for purchase online through the Microsoft website, in the shop section. The new product key must then be activated within 30 days, or it becomes no longer valid. It can be activated online or through the telephone. If it is not activated on time, features will stop working until the new key has been activated. This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary. 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.
