There is a lot of high resource utilization by any process that slows down a Windows operating system and one of the services that could cause such a thing is the utcsvc.exe process. This particular process at times can cause high CPU and disk usage. So if you are currently facing this problem, read on as this post will guide you on how you can resolve the problem. UTC which stands for Universal Telemetry Client is a software that runs a service named Diagnostic Tracking Service or DiagTrak. This service is used by Microsoft to collect customer feedback, analyze customer’s problems, and push resolution via updates in order to make the Windows 10 operating system better. This service is an executable file that could be translated to Service Host and even though the process does not usually cause problems, there are actually times when it does especially if it results in high resource utilization. In such cases, you might want to consider disabling it to fix its high CPU and disk usage.

According to Microsoft:

“We collect information about you, your devices, applications and networks, and your use of those devices, applications, and networks. Examples of data we collect include your name, email address, preferences, and interests; browsing, search and file history; phone call and SMS data; device configuration and sensor data; and application usage.”

There are several ways you can disable the utcsvc.exe process. You can disable it using the Service Manager, Registry Editor, and Group Policy Editor. For more details, refer to the instructions laid out below.

Google Chrome 94 is here and it has introduced a controversial idle detection API. For those people that do not know what idle detection API is, well basically Chrome can be asked by a website to report when a user of the site has a site open and is idle on the device. The issue that people have with this is that this particular feature can be used to report when the user is not using a computer at all. Good thing is that website or web application will prompt you to allow it to use this feature like when a site/application wants to use your microphone or web camera. Developers are on board with this feature since it can provide them with more telemetric data on how users are interacting with their website/application but there are some that are strongly voicing against this. Tantek Çelik, Mozilla Standards Lead, commented on GitHub, saying:

As it is currently specified, I consider the Idle Detection API too tempting of an opportunity for surveillance capitalism motivated websites to invade an aspect of the user’s physical privacy, keep long-term records of physical user behaviors, discerning daily rhythms (e.g. lunchtime), and using that for proactive psychological manipulation (e.g. hunger, emotion, choice)… Thus I propose labeling this API harmful and encourage further incubation, perhaps reconsidering simpler, less-invasive alternative approaches to solve the motivating use-cases.

Others who have spoken against this feature are people from the WebKit development team inside Apple. Ryosuke Niwa, an Apple software engineer who works on WebKit said:

That doesn’t seem like a strong enough use case for this API. For starters, there is no guarantee that the user won’t immediately come back to the device. Also, who is such a service supposed to know what another device user might be using at any given point? We’re definitely not going to let a website know all the devices a given user might be using at any given point. That’s a very serious breach of the said user’s privacy. It seems to me that such a suppression/distribution mechanism is best left for the underlying operating systems/web browsers to handle.

Of course, technology itself as always can be used for good or for bad and time will tell if this feature has brought good stuff or it has paved another brick in surveillance and privacy manipulation. As said for now option will prompt for agreement and let's hope that it will be used for good causes from this day into the future.

The Control Panel is one of the most important tools in Windows which allows users to control and change various settings. However, there are cases when it experiences some problems like when users aren’t able to open it. Recently, a lot of users complained about not being able to open the Control Panel. To be more specific, users were able to open it but only lasted for a second, and then it’s gone. This is not just some issue you can ignore as this will prevent you from accessing some major settings in your computer and you won’t be able to perform some important task without it. According to security experts, this issue is most likely caused by a bug in the Windows Update. If you have installed an update recently, then it’s most likely the culprit. Aside from the Windows Update, there are also other things that can cause this issue. Some of them are the IDT audio panel and a control panel file that causes conflicting issues with the control panel that leads to this problem. Aside from these aforementioned cases, the Windows Error reporting services could also be one of the causes of this issue. As you can see, since there are a lot of possible causes for this problem, this post prepared a lot of options as well which you have to check out. Follow each one of them and see which one worked best for you.

Option 1 – Try updating your Windows 10 PC

If you haven’t updated your PC to the latest version of Windows 10, then you should. A lot of users found that the issue with the Control Panel was fixed right after they updated their Windows 10 PCs. This is probably because Microsoft has probably released a fix on one of the latest updates.

Option 2 – Try uninstalling the IDT Audio Panel

For some users, uninstalling the IDT Audio Panel from their PCs did the trick. You can also try doing the same thing to fix the vanishing Control Panel. According to these users. The IDT audio panel was the one that’s causing the issue. To uninstall the IDT audio panel, here’s what you have to do:

• Tap the Win + R keys at the same time to open the Run dialog box.
• Then type in “appwiz.cpl” in the field and tap Enter to open the “Uninstall or change a program” screen of the Control Panel.
• From there, look for the IDT audio panel, select it and then select the Uninstall option and follow the next on-screen instructions that appear.

Note: If you are unable to locate the IDT audio panel or you simply can’t access the Uninstall or change program screen or you can’t keep Control Panel open for a long time, here’s what you can do:

• Tap the Win + R keys at the same time once again to open the Run dialog box.
• And in the field, type in “devmgmt.msc” and hit Enter to open the Device Manager.
• After opening the Device Manager, look for the “Sound, video and game controllers” option and double-click on it.
• From there, locate the IDT audio panel or “IDT High Definition CODEC” and select Uninstall and follow the next instructions that appear.

Option 3 – Try deleting or renaming IDTNC64.cpl

IDTNC64.cpl is a control file in the control panel. However, it might be the one that’s causing the problem as it could be conflicting with the control panel. As a result, the control panel crashes after a second or more. Many users have fixed the problem by either renaming or deleting this file – the safer option would be is renaming it.

• Tap the Win + E keys to open File Explorer.
• In the address bar located at the top, type in “C:\Windows\System32” and tap Enter to open this folder.
• From there, look for the IDTNC64.cpl file, right-click on it and select the Rename option.
• You can name the file anything you want but it’s better if you rename it to “oldcpl”.
• After you rename the file, try opening the Control Panel again. It should work fine now.

Option 4 – Try to disable the Windows Error Reporting Service

As mentioned earlier, the Windows Error Reporting Service is also known to cause the issue so some users disable it and got the issue fixed.

• Tap the Win + R keys.
• In the field, type in “MSConfig” and hit Enter to open System Configuration.
• After opening System Configuration, go to the Services tab and look for the Windows Error Reporting Service and uncheck its checkbox.
• Click the Apply button and click OK. You should now see a date in the Disable Date column. Then check if the Control Panel is now working properly if not, restart your computer and check once more. That should fix the problem.

Option 5 – Try opening Control Panel via Run

This option is more of a workaround than a solution as it does not really fix the issue with the Control Panel but rather helps you in accessing the controls at the very least.

• Tap the Win + R keys to open Run.
• Type in “appwiz.cpl” in the field and tap Enter to open the Uninstall or change program screen of the Control Panel.
• Next, copy and paste “Control panel all control panel items” on the address bar located at the top-mid part of your screen. You must not type the given address and simply copy and paste it. After that, you will see a list of control panel controls you can use.

A slow PC startup can be pretty annoying. This usually results from various computer issues. If your computer is acting sluggishly, here are four ways to speed up your PC startup.

As you know, Windows has a built-in Automatic Maintenance feature that takes care of important tasks such as security scanning and updating, Windows software updates, Disk Defragmentation, System Diagnostics, Disk Volume Errors, and many more. So if you receive an error message saying, “Windows is unable to run automatic maintenance, The maintenance schedule is unavailable”, then this post will guide you in what you can do to resolve this issue. Here are some suggestions you can try if the Automatic Maintenance in your Windows 10 PC is not able to run.

• Next, look for the “MaintenanceDisabled” key and then double click on it to open it and then set its value to “0”.
• Click OK and exit the Registry Editor.
• Restart your computer.

Option 2 – Check the Task Scheduler Services status

Majority of the tasks in Windows 10 run via services. So it is most likely that either the Service has been stopped or is set to the manual which is why Windows is unable to run Automatic Maintenance. Thus, you need to change it to automatic mode.

• Tap the Win + R keys to open Run.
• Type “services.msc” in the field and hit Enter to open Services.
• Next, look for the Task Scheduler service and tap the T key on your keyboard which should take you to the services that start with T.
• Double click on the Task Scheduler service and select the Automatic option under the Startup Type.
• If it is not started yet, click on the Start button.
• Then click Apply and OK to save the changes.

Option 3 – Check the Status in Task Scheduler

You can also try checking the status in the Task Scheduler. Just open the Task Scheduler > Task Scheduler Library > Microsoft > Windows > TaskScheduler. From there, make sure that Idle Maintenance, Maintenance Configurator, and Regular Maintenance are enabled.

Option 4 – Run the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Automatic Maintenance issue. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 5 – Run the DISM tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
• The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Restart your PC.
