In case you don’t know, Windows 10 now allows users to check the Bluetooth battery level of devices. More often than not, the accessories or peripherals users use for their Windows 10 devices are connected to it using Bluetooth technology. This high-speed low-powered wireless technology is designed to link mobile devices, computers, and other network devices over a short distance wirelessly. Monitoring the battery level of a device where Bluetooth is enabled isn’t an easy task as most of these devices do not support the Bluetooth battery monitor or the battery level display. And even when on devices that do, you still have to install additional software to find it. However, Windows 10 eliminates this requirement and all you have to do is add a Bluetooth device and connect that Bluetooth device. How? Follow the instructions provided below. Step 1: Adding a Bluetooth Device The easiest way to get your Bluetooth device battery to be displayed on your Windows 10 screen is to simply add a Bluetooth device. To do so, follow these sub-steps:

• First, turn on the Bluetooth mode on your device.
• Next, go to Windows Settings > Devices > Bluetooth & other devices.
• From there, click on the “+” button next to the ‘Add Bluetooth or other devices” option and select the type of device you want to add.

Step 2: Connecting the Bluetooth Device Once you’ve added the device, it will be visible under the “Add a device” screen.

Error Code 0x8007001 - What is it?

Error Code 0x8007001 occurs during installations that take place in Windows 10.  Various versions of this same error have also been present in previous editions of the software and the methods to resolve the error across these versions are the same

Common symptoms include:

• Inability to complete the installation process for updates, programs, and system versions.
• Installations quitting out in the middle of the process, particularly as the files are unpacked.

Several solutions for Error Code 0x8007001 require the user to complete semi-complex tasks. If you aren’t comfortable with the processes necessary to finish the methods below, make sure that you get in touch with a certified professional who is familiar with the Windows operating system to assist you in the resolution of the error code.

Solution

Error Causes

In many cases, Error Code 0x8007001 is caused by an installation disk that is not functioning properly or installation files that have been corrupted or changed. When this is the case, the operating system will not be able to begin actually installing the files and will instead hang up as the files are unpacked from the installation set.

Further Information and Manual Repair

For Error Code 0x8007001 to be repaired properly, the missing or corrupted installation files need to be repaired or the system needs to be able to recognize the files that it is missing. This can require some advanced computing knowledge. If you don’t feel comfortable with the idea of undertaking the methods below on your own, contact a computer repair technician who can assist you in following these steps.

Method One:  Load the Install Files on an Alternative Disk

In some cases, the operating system simply cannot recognize the installation files that are present on the disk in question, whether it is on a hard drive, a set of downloaded files, or files from a flash drive. If this is the case on your particular machine, the simplest way to work around the problem is to load the installation files onto an alternative disk source, whether it be a flash drive, CD, DVD, or secondary hard drive. After these files have been properly loaded onto that alternative disk, attempt to run the installation from the alternative source instead.

If this method is successful, it means that the system may have had trouble recognizing the files involved in the installation from the first source, but that the files themselves were not corrupted or changed.

Make sure that you save the alternative disk source after your installation is complete in case you ever need to do a fresh installation on your machine.

Method Two:  Clean Your Disc and Your Drive

If you are installing files from a DVD or CD, check to make sure that the back of the disc is free from scratches and dust. If there are no visible marks on the disc, you may need to open up your disk drive to see if there is a build-up of dust or debris inside of the drive. If this is the case, simply clean your drive and re-attempt your installation process from the included disk.

Method Three:  Run the Windows Update Troubleshooter and Update Your Programs

If the error code is still appearing on your machine, you can open up your Windows Update tool and run the troubleshooting wizard, which will then scan your machine to see if there are any potential problems that it can fix. Next, run the Update tool itself if there are any updates that need to be performed. Sometimes, this can resolve the error at hand. Make sure to restart your computer after any updates or changes have been made so that you can ensure that they are applied by the operating system appropriately.

Method Four: 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.

‘R6025 pure virtual function call’ is a runtime error that occurs suddenly on the screen and disrupts the program being run prior to it. This error display indicates that the program has been corrupted. R6025 runtime error usually occurs with the Visual C++ framework.

Solution

Error Causes

This error occurs when the C++ program crashes which is usually because of the malfunctioning or missing of the device driver or incomplete device driver files. It happens because your application indirectly calls a pure virtual member function in a context where a call to the function is invalid. Most of the time, the compiler detects it and reports it as an error when building the application. R6025 error is usually detected at run time.

Further Information and Manual Repair

To fix the R6025 pure virtual function call error, you need to find the call to the pure virtual function. After you find the call, you need to rewrite the code so that it is not called again. There are 2 ways to do this:

Alternative 1

One way to fix the R6025 pure virtual function call is to replace the function with an implementation that calls the Windows API function DebugBreak. The DebugBreak causes a hard-coded breakpoint. Once the code stops running at this breakpoint, it is easy for you to view the call stack. By viewing the call stack you can identify the place where the function was actually called.

Alternative 2

Another quick way to find a call to a pure virtual function to fix the R6025 error is to set a breakpoint on the _purecall function that is usually found in PureVirt.c. By breaking this function you can trace the problem occurring and rewrite the call to ensure the error does not occur and the program you are trying to develop on the Visual C++ framework is easily developed. If R6025 Error is related to Windows Registry Problem Then here’s how you can fix the problem: To fix the runtime error R6025, run registry cleaner software to scan and fix all errors.  This alternative is suitable if the R6025 error is related to the Windows registry problem and where the error has occurred due to corrupted or malicious registry entries.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the Windows Defender error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• 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 check if the problem is fixed or not.
