Error 740 Requested operation requires elevation
If you are trying to open a folder or run a program or delete a file but you encounter an error message instead saying, “Error (740), The requested operation requires elevation” on your Windows 10 computer, then this post should help. Make sure that you follow each one of the options given below carefully.

Option 1 – Always run the program as an administrator

There are some apps that require administrator privilege before they can be opened. So if you are got the “Error (740), The requested operation requires elevation” error when you try to open a particular app on your computer, you have to try opening it as administrator instead. On the other hand, if you are already using an administrator account or if you are a member of the administrator group, this option may not work for you so just proceed to the next one but if you’re only using a regular account, then follow these steps:
  • First, right-click on the app you are trying to open and select Properties.
  • After that, go to the Compatibility tab and check the checkbox labeled “Run this program as an administrator”.
  • Next, click the Apply and OK buttons and see if the app opens without any problem.

Option 2 – Try to change the folder permissions

If you encounter Error 740 while opening a folder, then you need to try changing the folder permissions.
  • First, right-click on the folder and click Properties.
  • Next, go to the Security tab and click the Advanced button.
  • After that, check the checkbox labeled, “Replace all child object permission entries with inheritable permission entries from this object” and then click the Apply and OK buttons to save the changes made.

Option 3 – Try disabling UAC

The User Account Control or UAC settings might be the one that’s responsible for Error 740 which is why you have to disable the User Account Control and then verify if it’s the one that triggers the error or not. To do that, simply search for “Change user account control settings” in the Taskbar search box and then drag the blue bar down to the bottom and click the OK button to save the change made.

Option 4 – Select the Elevate without prompting option in the Group Policy Editor

There is an option in the Group Policy Editor which allows you to disable the UAC prompt. Disabling the “Elevate without prompting” option can help in resolving Error 740 and to disable it, follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
  • Next, navigate to the following path:
Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options
  • From there, go to the Security Options folder where you can find a policy named “User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode”. Double click on it to open its options.
  • Now select the Elevate without prompting option from the drop-down menu and click OK.

Windows laptop turns off when unplugged
If your Windows 10 laptop suddenly turns off when you unplug its power cord, then you’ve come to the right place as this post will guide you on how you can fix this issue. One of the most common causes for this kind of issue is that there is some problem with your laptop’s battery. It is possible that it might have gone bad or has been damaged. However, this couldn’t be the case especially if the laptop is new. The problem could have something to do with the system settings, connections, laptop hardware, and so on. To fix it, there are various suggestions you can check out such as follows:

Option 1 – Perform a hard reset on your laptop

This option works in most cases when the laptop with a removable battery is charging slowly as it is plugged in constantly. Refer to the steps below to do a hard reset on your laptop.
  1. Switch off the power of your laptop.
  2. Disconnect your laptop’s charger and then remove the battery.
  3. Tap and hold the power button for at least 30 seconds – doing so will discharge the capacitors of the motherboard and reset the memory chips that were active constantly.
  4. Plug the battery back and then charge the laptop again.
Check if the problem is fixed, if not, proceed to the next option below.

Option 2 – Try to change the Power Options

  • Tap the Win + R keys to open the Run utility.
  • Then type “powercfg.cpl” and tap Enter to open the Power Options window.
  • Next, go to your selected power plan and click the “Change plan settings” option to open a new page.
  • From there, click on the “Change advanced power settings” option. This will open a new window where you can see various power consumption options.
  • Now on the next window that appears, click on “Change advanced power settings”. This will open another window where you have to expand the Processor power management > Maximum processor state.
  • Then change the value for On battery mode to 25% and enable Adaptive brightness.
  • Now shut down your computer and try to boot it with the power cord unplugged.

Option 3 – Try to run the Power troubleshooter

The next thing you can do is to run the Power troubleshooter. To do so, follow these steps:
  • Go to Settings and navigate to Update & Security > Troubleshoot.
  • After that, look for the “Power” option from the given list of built-in troubleshooters and click on it.
  • Next, click on the “Run the troubleshooter” button to run the Power troubleshooter.
  • Once the troubleshooter is done identifying the problems, follow the next on-screen instructions to resolve the problem.

Option 4 – Try to run the Power Efficiency Diagnostics Report

You could also try to run the Power Efficiency Diagnostics Report to fix the problem. This tool is helpful and will help you analyze the status of the battery but note that this can be quite overwhelming especially if you’re not well-versed in this matter.

Option 5 – Try to uninstall or reinstall the Battery driver

You might also want to uninstall or reinstall the battery driver as it can also resolve the problem. But before you start, you have to shut down your computer and remove the power chord as well as the battery. Once you’re done, follow these steps:
  • Plug the power cord and restart your computer.
  • Once your computer has restarted, tap the Win + R keys to open the Run utility and type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
  • After that, look for the “Batteries” driver from the list of drivers and expand it.
  • Then right-click on the “Microsoft ACPI-Compliant System” driver and click on the “Uninstall device” option.
  • Once it’s done, restart shut down your computer and remove the power cord and then attach the battery.
  • Now attach the power chord again and restart your computer to automatically install the driver.

Option 6 – Try to update the BIOS

Updating the BIOS can help you fix the problem but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “msinfo32” in the field and press Enter to open System Information.
  • From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
  • After that, you should see the developer and version of the BIOS installed on your PC.
  • Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
  • If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
  • Now double click on the downloaded file and install the new BIOS version on your computer.
  • Now restart your computer to apply the changes made.
Note: If updating the BIOS didn’t help, you might want to consider resetting it instead.

Disable or Enable App Launch Tracking
The Windows 10 operating system utilizes a variety of measures in order to track your app launches so that it can boost both your start and search results. It can personalize the start menu based on the apps that you use the most on the Start menu as well as the search results. This way, the App Launch Tracking is definitely useful especially when you want to access your favorite and frequently used apps quickly in the Start menu and search results on your Windows 10 computer. On the other hand, Windows 10 provides users with the ability to control their privacy settings in order to protect the privacy of users. Windows 10 users can either opt to enable the app launch tracking to improve the start menu and search menu or opt to disable the app launch tracking in order to prevent the Windows operating system from tracking that you open if you really value your privacy that much. Whichever setting you prefer, you need to change the privacy control settings as well as make some tweaks in the Windows Registry in order to turn on or turn off the app launch tracking feature.

Option 1 – Turn off or turn on app launch tracking via Settings

  • Go to Settings and click on Privacy.
  • After that, toggle On the “Let Windows track app launches to improve Start and search results” option on the right side of the page under the General Settings to enable the app launch tracking feature.
  • And of course, if you wish to disable the app launch tracking feature, simply toggle Off the “Let Windows track app launches to improve Start and search results” option on the very same page under General Settings.
  • After that, close the Settings window.
Note: Keep in mind that when you disable the app launch tracking feature, the “Show most used app” setting will either be grayed out or labeled as “Disable” on your Windows 10 computer. Thus, if you want to keep viewing the most used apps, just re-enable the app launch tracking feature if you have disabled it.

Option 2 – Turn off or turn on app launch tracking via Windows Registry

Before you proceed, make sure to create a System Restore point
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
  • Next, navigate to the following path:
HKEY_CURRENT_USERSOFTWAREMicrosoftWindowsCurrentVersionExplorerAdvanced
  • After that, right-click on the Advanced folder and then click on New to create a new 32-bit DWORD value.
  • Name the newly created DWORD as “Start TrackProgs” and set its value to “1” to enable the app launch tracking feature.
  • If you want to disable the app launch feature, set “0” as the value instead of 1.
  • Now click OK and restart your computer.
Take note that you still have to create a 32-bit DWORD value even if you are using a 64-bit Windows computer.

How to block websites in Windows
There are a lot of reasons to ban or block different websites in your Windows. From wanting to limit yourself from distraction to block certain sites for sake of kids not going into them. Whatever your reason might be, keep reading in order to find out how you can block any website inside Windows for all browsers. The technique I am going to share with you is universal and not tied to Windows versions, they will work in any Windows from XP onward. Also, the technique will block desired websites on any browser, already installed or even ones that will be installed after doing the trick. And we will also be looking at applications that can help you in this task if you do not wish to do it manually.

Block websites using dedicated software

A small free application called Focal Filter which can be found here: https://www.focalfilter.com/ is a software solution for your needs. It is a pretty straightforward and easy-to-understand application and not really much can be said here about it. You simply download and install it, set your websites, and you are done, the app does rest.

Blocking manually via host file

Another method besides mentioned one using the dedicating application is to manually set site addresses inside the Windows host file. The first thing, of course, is to open the host file, run a notepad with administrator privileges, go to file open, and navigate to c:\windows\system32\drivers\etc\hosts. Once the file is opened go all the way down and add: 127.0.0.1 SITENAME For example: 127.0.0.1 www.youtube.com or 127.0.0.1 www.facebook.com This way each time user on a PC tries to access a listed website computer will reroute it to the given address which is your PC's local address and asked website will not be able to load.

Identify resource hogging applications
Resource hogging is a term when one single application or few of them are taking all system resources for themself causing extreme slow down in the computer and nonresponsiveness. It can be a very frustrating and time-consuming experience and it can cost you money if you can not finish work on time due to this effect. I believe that everyone has experienced at least one slowdown in their IT carrier because of resource-hogging applications and most users do not know how to deal with this. We are here to help you with this issue. Just to be aware that this method shown here is not a method to miraculously speed up your PC or anything similar, this is to be able to detect and recover from extreme slowdowns. Hardware components are still very important and if you can upgrade your computer if it is outdated, please do it because new applications will require a more modern system, and not any kind of tips and tricks will save you from outdated hardware.

Identifying resource hogging app

Now when we got that out of the way let's talk about slowdowns, it is no secret that sometimes an application has bugs and memory leaks that can cause this kind of behavior, and sometimes the application simply takes up too much memory for any other application to work normally. The most simple and straightforward way is to bring up a Windows task manager and inspect running applications and services. You can bring task manager by the key combination of CTRL + SHIFT + ESC If the system is in deep memory deficit you will have to wait for the task manager to open and show itself on-screen. Once opened, click on more details if that view is not opened by default. Once the view expands you will see all running applications with how much RAM memory have they taken and how much CPU they are using.

What to do with app?

Now you are presented with a choice on what to do with the problematic application. If you press the end task button on the bottom right, Windows will kill the application and its processes but any unsaved work inside the application will be lost and unrecoverable in most cases. Or you can try to remove smaller applications running to free up more memory and CPU in order for the computer to catch up. Any choice you make is up to you, but be very careful not to kill Windows essential service by mistake, that will cause immediate system instability with high chances of a system crash.

How to place control panel in File explorer
Recent Windows updates have been slowly but surely moved a lot of control panel features into settings. This indicates that in the long term goal is probably to get rid of the control panel altogether. No matter how the setting app is easy to use and good there are still things in the control panel that we need and we will still need until they are all moved in the setting application. There are several ways to open and get to the control panel from run dialog to shortcut keys but one perhaps more convenient and easiest way is to just simply have in file explorer right beside hard drives double click away. In order to place the control panel icon inside file explorer, we will need the help of our old friend: the registry editor. As always playing with the registry editor can cause some instability and it is always a smart thing to back up it first before attempting any kind of edits.

Registry editor adding a key
