Error Code 0x80070017- What is it?

Error Code 0x80070017 is an error code that is most often associated with Windows 10 installations, although it has also been encountered by users on previous versions of the Windows operating systems. It is usually encountered as users attempt to install a new version of the software on their machine.

Common symptoms include:

• A vague error message regarding the inability of the system to copy over the necessary files pops up as users attempt to install a new version of the Windows operating system on their computer

While it can be hard to tell what the exact cause of Error Code 0x80070017 is on your specific device, the good news is that there are two primary methods that can be used to fix the problem and to allow you to proceed with your installation. These two methods do require some degree of technical knowledge and/or skill, so if you don’t feel like you have the ability to undertake them on your own, be sure to get in touch with a trusted computer repair professional to assist you.

Solution

Error Causes

The most basic cause of Error Code 0x80070017 is that some of the files that are needed by the system to complete the installation are either not being found by the computer or are believed to be corrupted by the system. When this happens, security features within the software prevent it from completing the installation process, so as to avoid damage to the computer. Error Code 0x80070017 can be disruptive to your installation process, but there are two basic methods that can be employed to resolve it.

Further Information and Manual Repair

While it can be frustrating to encounter Error Code 0x80070017 on your Windows machine, there are two methods that can be used to try to resolve the problem. One of these methods is extremely simple, even for the most basic users, while the second method takes a little bit more skill and technical knowledge. If you aren’t able to complete these methods on your own, be sure to get in touch with a qualified computer repair technician that can assist you. Here are the best ways to attempt to resolve Error Code 0x80070017 on your device:

Method One:  Clean Your Physical Disk

If you purchased a physical disk version of the installation files for your Windows operating system, remove the disk from your drive and clean it using a microfiber or other lint-free cleaning cloth. As you wipe down the disk, do not use any chemicals, and be sure to wipe gently from the center towards the outside edge rather than the other direction, as failure to do so can damage the disk irreparably.

In some cases, you may need to contact Windows support if you believe that there is an error on the disk itself, such as a scratch, that would prevent the disk from being used as needed in the installation process. They may be able to offer you a replacement disk or you may be able to download a digital copy of the version that you are attempting to install on your machine.

Method Two:  Use the Chkdsk Utility

To determine if there may be an error within the disk drive itself, place the installation disk into the drive and restart the system. Go through the prompts until you see the option to “repair your computer.” Choose the operating system that you are using, go into the menu for System Recovery, and type in the words “Chkdsk/r” to begin to use the tool.

Whenever you run a tool like Chkdsk on your computer, it is important to restart your machine afterward to ensure that any changes that have been made are able to be fully applied and accepted by the operating system that you are running.

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.

The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way. This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success). Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

"An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights."

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.

Windows 10 is by far the most personalized Windows so far, most of its personalization comes from him learning our habits on computers and setting future experiences taking them into account.

Low on Memory is a Windows PC memory leak error. You may come across it out of the blue however, there are various underlying reasons for this PC error. It is like a warning sign that indicates memory/RAM issues on your system. The ‘Your Computer is Low on Memory’ error means that your PC does not have enough memory space for all the activities you are trying to perform. Due to this error, your Windows and programs can also stop working. If this error is not fixed timely it can lead to serious PC threats like valuable data loss and hard disk corruption. Along with this memory error, you may also come to experience other types of signs including PC poor performance, speed issues, out-of-memory notifications, and display problems.

Solution

Error Causes

The ultimate and the underlying cause of low memory error is data overload in the RAM which triggers registry issues. To understand this better, here is a comprehensive explanation. The computer has 2 types of memory, RAM (Random Access Memory) and virtual memory. All programs and activities that you do on your computer are saved by the registry in the RAM. This includes obsolete and unnecessary files too like junk files, cookies, internet history, temporary files, invalid registry entries, and bad registry keys. Due to poor PC maintenance practices, these files accumulate in the RAM, thereby overloading it. Also, all programs on the PC use RAM to run. So, when there isn’t enough RAM for the program you are trying to run on your system, Windows temporarily moves information that would normally be stored in RAM to a file called a paging file which is also referred to as the virtual memory. By moving the information to and from the paging file- the virtual memory, Windows temporarily frees up enough RAM for programs to run smoothly. However, when you start running more programs than the RAM installed on your PC can support, low memory errors begin to occur. It triggers that the computer is out of RAM and is also low on virtual memory.

Further Information and Manual Repair

PC users should know that this is a critical error therefore it is advisable to fix it immediately before the damage sets in. Here are some of the best solutions that you can try to resolve Your computer is low on memory and similar memory leak errors on your system.

1. Run Few Programs at a Time

This is a temporary solution to prevent low memory problems.  By running a few programs at one time you can easily keep this memory error away from popping on your computer screen. However, this can cause you inconvenience if you run several programs together to perform different tasks simultaneously.

2. Increase the Virtual Memory Size

Though Windows automatically attempts to augment the virtual memory size the first time you experience ‘low on memory issues; however this again is a temporary way out of this problem. But if you are looking for a solution that can resolve these memory issues for a long time, then you can try manually increasing your PC’s memory size. Increase it up to a maximum size this is by the way determined by the amount of RAM installed on your system. Nonetheless, the drawback of this solution is that increasing the paging file size can reduce your PC performance. It can make your programs run more slowly.

3. Install More RAM

Another solution to resolve low on memory issues is to install more RAM. To do this first check your system properties to see the size of the RAM already installed on your PC. To do this press the Windows key+ Pause/Break key this will open system properties. If the RAM size is lower than 2 GB then you need to install more RAM. But if it is more then you should look for two things one check the piece of software that is causing the problem and secondly you need to clean the registry and remove the unnecessary files from your RAM and hard disk.

One of the most interesting innovations that were released by Microsoft is the Surface Dial. This only goes to show that Microsoft is very competent not just in hardware but in overall innovation. Although it’s quite a piece of technology and as far as the consensus is concerned, it works pretty well, there are still some issues encountered by users. One of the particular issues experienced by users is that the Surface Dial fails to pair with every Windows 10 PC. At a time of writing, it is still not clear what the cause of the problem really is. However, their possible solutions are provided in this post that might help you resolve the problem. Before you get started troubleshooting the problem, make sure that there are two AAA batteries fitted inside properly.

Option 1 – Check if your PC supports Bluetooth 4.0 LE

In case you don’t know, the Surface Dial only works with the Windows 10 Anniversary Update and later PCs that support Bluetooth 4.0 LE. Thus, you have to check if this is supported or not before you troubleshoot further.

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, click on Bluetooth and select “Microsoft Bluetooth LE Enumerator” from the drop-down menu. However, if it is not there, then it simply means that your computer does not support this standard which is most likely why you were unable to pair with other Windows 10 PCs. On the other hand, if you were able to see it, then proceed to the next troubleshooting steps below.

Option 2 – Check if Bluetooth is on

The next thing you have to do is to check if Bluetooth is turned on. As you know, the Surface Dial connects to your computer using Bluetooth and so you need to check if it’s really on or not. Aside from that, you also have to verify pairing.

• Tap the Win + I keys to open Windows Settings.
• Next, select Devices from the menu and click on Bluetooth.
• After that, make sure that the toggle switch for Bluetooth is turned on.
• Now all you have to do is to verify pairing by pressing and holding the pairing button located beside the batteries and then wait for a few seconds until the Bluetooth light begins to flash.
• Then go back to the Bluetooth section and click on Bluetooth or other devices.
• From there, click on Add Bluetooth and select Surface Dial.
• Follow the next instructions on the screen and click on Done once everything is completed. That should fix the problem.

Option 3 – Check if Surface Dial is connected to another PC

If you think that connecting a Bluetooth device to two different PCs at the same time is wise, then think again as it does not really bode well for the overall user experience. Thus, you need to disconnect the Surface Dial from the system that you are currently using. On the other hand, if everything fails, then it’s most likely that the Bluetooth adapter is the one at fault. So you may have to get a third-party device that connects to your system via USB and then see if it works or not.
