Adjust For Daylight Saving Time Automatically Is Grayed Out In Windows 11/10

If you live in the USA or some other countries where Daylight Saving Time is available, but find that the setting is not working on your Windows 11/10 computer, then this post will show you is how to fix it. If the Adjust for daylight saving time automatically option is grayed out in the Windows Settings panel, here are some troubleshooting suggestions that might be helpful for you.

What is Daylight Saving Time setting in Windows 11/10

Daylight Saving Time or DST is a common practice in the United States and some other regions. If the Daylight Saving Time option is activated on your PC, your system will forward the clock one hour from standard time in the summer and revert the change in the fall. It does this so that users can utilize the sunlight or daylight better during that period.

Like some other devices, Windows 10 has this feature as well. However, if it is not working on your PC or the option is grayed out in the Windows Settings, you can fix it with the help of this guide.

Adjust for daylight saving time automatically is grayed out

To fix Daylight Saving Time is grayed out error in Windows 11/10, follow these suggestions-

Change Time Zone

Enable DST from Registry Editor.

1] Change time zone Windows 11

Select Time & language settings from the side panel on the left.

When directed to a new screen, locate the Time zone heading and hit the drop-down menu next to it, and select a different time zone where Daylight Saving Time is available.

Windows 10

As mentioned earlier, DST is available only in a few countries around the world. You may, therefore, need to change the Time Zone so that Windows 10 can enable this functionality.

Press Win+I to open Windows Settings, and go to Time & Language setting. Make sure that you are in the Date & time tab. If so, you can expand the Time zone drop-down menu, and select a different time zone where Daylight Saving Time is available.

2] Enable DST from Registry Editor

If the solution, as mentioned above, is not working for you, you must force the adjustment from Registry Editor. For that, open Registry Editor on your PC, and navigate to this path-

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTimeZoneInformation

Make sure that the Data is set to zero (0). If not, you can set that specific data and check if the DST setting is enabled or not.

If you want to force-update the DST adjustment, you can set the Data to one (1).

I hope this works for you.

What is the purpose of Daylight Savings Time?

The sole purpose of Daylight Saving Time is to make better use of daylight by tweaking the clocks to move an hour of daylight from the morning to the evening. It is done during the summer months and hence, also known as Summer Time. Research suggests Daylight Saving Time helps in cutting short the entire country’s electricity usage by a small but significant amount.

What is the rule for Daylight Savings Time?

The daylight saving time (DST) period in the U.S. kickstarts each year on the second Sunday in March when clocks are set forward by one hour. The process is reversed and changed back to standard time on the first Sunday in November when DST ends.

How To Fix Microsoft Compatibility Telemetry High Cpu

The Microsoft Compatibility Telemetry or Windows Compatibility Telemetry is a program that periodically sends your diagnostic and usage data to the Microsoft server. Microsoft uses this information to introduce new features and resolve bugs in the system.

By default, your system runs this process periodically, during which it can consume a significant portion of your system resources. If it causes high CPU usage, your computer slows down considerably and impacts you from doing any tasks on your system.

The only way to resolve the issue is by disabling this process. There are many ways to do so on a Windows system, which we have mentioned below. Depending on your current system configuration, you may need to perform one or more solutions to resolve your issue.

The Microsoft Compatibility Telemetry is a part of the complete Telemetry or Diagnostic Data windows component. Windows Settings allow you to choose if you want to send only the required diagnostic data to Microsoft or optional data as well.

If you enable sending optional diagnostic data, this telemetry process will use more resources. So you can try disabling this option and see if it fixes the issue.

Press Win + I to open Settings.

Go to Privacy & Security or Privacy and then Diagnostic & feedback.

Select Delete under Delete diagnostic data.

You can also try disabling the Connected User Experience and Telemetry service. The Microsoft Compatibility Telemetry program uses this service for its operation. So, disabling the service prevents the program from running. To disable the service,

Open Run by pressing Win + R.

Type services.msc and press Enter to open Windows Services.

It is also possible to disable optional telemetry operations on your system using the Local Group Policy Editor to avoid high CPU usage of this process. Here’s how to can do so:

Open Run.

Type gpedit.msc and press Enter to open the Local Group Policy Editor.

Restart your PC to apply the change.

Windows Home users do not have the Local Group Policy Editor by default. In such scenarios, you can disable the Allow Telemetry setting from the Registry Editor.

Open Run.

Type regedit and press Enter to open the Registry Editor.

Navigate to ComputerHKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsDataCollection

Then, go to ComputerHKEY_CURRENT_USERSOFTWAREPoliciesMicrosoftWindowsDataCollection

The different telemetry processes run at separate intervals or instances. By default, Microsoft Compatibility Telemetry runs every day at a certain time by default regardless of whether the user is logged in or not.

If you are experiencing high CPU usage due to this process, you can disable this task through the Task Scheduler. Here are the necessary steps:

Open Run.

Type taskschd.msc and press Enter to open the Task Scheduler.

If you don’t think you’ll ever need to send compatibility diagnostic data to Microsoft, you can permanently delete the Microsoft Compatibility Telemetry program or CompatTelRunner.exe from your system.

However, this program is under the ownership of Windows NTTrustedInstaller by default. So you will need to take ownership and provide full permission of the file to your user account to delete it. Here is the complete process:

Log into an administrator account on your PC.

Open Run.

Type cmd and press Ctrl + Shift + Enter to open the Elevated Command Prompt.

Enter the following commands to take ownership of the CompatTelRunner.exe file and provide permissions to modify it:

takeown /f “%WinDir%System32CompatTelRunner.exe” /a

Then, you can delete the file using the command del “%WinDir%System32CompatTelRunner.exe”

Alternatively, you can rename it to something else to leave a backup. To do so, use the command: ren “%WinDir%System32CompatTelRunner.exe” CompatTelRunner.old

.Net Runtime Optimization Service High Cpu Windows 11/10

If you’ve experienced your computer suddenly slowing down, you might have checked the Task Manager and found a process called .NET Runtime Optimization Service (Mscorsvw.exe) causing high CPU usage in Windows 11 or Windows 10. This process can be puzzling, but this article will help you understand what it is and provide you with solutions to resolve the high CPU usage issue.

Also see: What is Microsoft Edge WebView2 Runtime and How to Uninstall it?

.NET Runtime Optimization Service, also known as chúng tôi , is a core component of Windows. It is a Windows service that pre-compiles .NET assembly files, making the launch of programs made in .NET framework much faster.

You must have used some apps built with .NET Framework without even realizing it. The .NET Runtime Optimization Service is responsible for optimizing your Windows to make apps launch much faster. By default, the service runs in the background when it detects that your PC is in idle mode, and once the compilation is complete, it will stop.

However, depending on the number of .NET programs you have installed, the size of those programs, and your PC’s performance, it may take some time for the service to complete its run, causing high CPU usage in Windows 11/10 during the process.

The service can also appear in multiple chúng tôi processes, causing high CPU, RAM, or Disk usage spikes up to 100%.

You do not need to worry about this process as it will go away by itself once its work is done. It will only run when a new app or program made in .NET Framework is installed on your system, or when you install the .NET Framework Redist.

If the .NET Runtime Optimization Service runs endlessly at high CPU usage, the problematic program might be the one causing the issue. Instead of disabling the process, try fixing or removing the program first.

If the CPU resource consumption by the process bothers you, or if you want to stop the service entirely, read below.

Before disabling the service, try to speed up the process. By doing this, it can get its work done faster, and you can then get on with other things.

After the change, the .NET Runtime Optimization Service may cause temporary high CPU usage and spike up to 100%, but this will allow the service to run at maximum speed, completing its work faster. Once its job is done, it will go away by itself.

We don’t recommend disabling the service, but if you prefer to do so, you can disable the .NET Runtime Optimization Service in the Services setting. Here’s how:

Press Win+R keys on your keyboard to open Run window.

Type chúng tôi and hit Enter.

Close the Services panel and restart your PC to see if the issue is resolved.

If you have no access to the Services panel or you just prefer to do it the other way, you can disable the service via Registry Editor. Please keep in mind that registry editing may cause serious problems if it is done incorrectly. Backup your registry before modifying anything and do it at your own risk.

Go to the start menu or press Win+R key. Type regedit to open Registry Editor. Navigate to the following registry folder. If you see multiple clr_optimization folders, select the latest version number.

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesclr_optimization_(version number)

Once done, close the Registry Editor and restart your computer. Verify if the high CPU usage problem is fixed.

The .NET Runtime Optimization Service is a core component of Windows that pre-compiles .NET assembly files so that apps made in .NET can launch faster. Although the service may cause high CPU usage in Windows 11/10, it will go away when its work is done.

If you experience endless high CPU usage, try to fix or remove the problematic .NET program first. If you want to stop the service entirely, you can disable it temporarily or permanently via Task Manager or Registry Editor, respectively. However, we do not recommend disabling the service, as it is typically doing something good for your PC.

What Is Spooler Subsystem App? Why Does It Have High Cpu Usage

Spooler Subsystem apps are integral in operating a printer and giving it commands to print, scan or send a fax. This Windows service is like a middleman between your PC and the printer. 

Thankfully, this issue is quickly resolved mainly through performing a software update or a quick clearing of the printer queue. The only way to tell if the spooler subsystem app is malfunctioning is when you open the task manager and notice that it’s taking too much of your CPU resources. 

Is the Spooler Subsystem App a Virus?

The spooler subsystem app comes by default with any Windows operating system and is completely safe and made to serve a specific purpose. However, malware is out there that masks ordinary processes to circumvent your antivirus systems.

What Causes High CPU Usage for the Spooler Subsystem?

Here is a list of the most common reasons why you get very high CPU usage for this application:

Your Printing queue is full: This is perhaps the most common reason why you get high CPU usage for the Spooler subsystem app.

Queuing of files set for printing enters a loop: Any loop would cause very high CPU usage, as it goes on indefinitely until stopped.

Your printer has encountered an error: If the printer encounters an error, it might constantly try to resolve it with the operating system – causing abnormally high CPU usage

Outdated drivers: In rarer cases, the problem is caused due to an improperly configured PC or printer driver.

Your system has malware masking as a Spooler subsystem app: Some malware are specially designed to mimic windows processes in order to bypass the defenses.

How to Fix Spooler Subsystem App With a High CPU Usage?

As a non-essential Windows process, seeing that this application takes up more than 1% of your CPU is abnormal and is, in essence, wasted performance. This article will show you how to fix high spooler subsystem CPU usage as well as how to prevent this bug in the future. Here are the different ways to fix it:

Use the Built-in Troubleshooter

Let the process finish, restart your PC and check if the spooler subsystem’s high CPU issue persists. 

Clear the Printer Queue

Here are the steps to clear the printer queue:

Disable the Process

A quick solution to temporarily resolve this issue is by forcing windows to stop running the process manually. Here are the exact steps to do so:

You will notice that it is completely gone if you check your task manager. While this fix works wonders, the con is that you might have to perform it every time you encounter a high CPU usage problem.

Update Your Drivers

Having the latest drivers for both your Printer and PC can prevent a spooler subsystem from malfunctioning. In general, there are two ways to update a printer’s drivers. The first is by using the built-in Windows driver update function, and the second is by using the printer manufacturer’s driver assistant application. 

Since every printer manufacturer has a slightly different proprietary app that can install drivers, we will show you the universal way to do so via the Windows Driver Update function:

After the procedure is finished, restart your computer and check if the high CPU usage issue persists. 

Reset Your Printer 

This last resort measure involves performing a factory reset on your printer. When a printer’s internal memory and settings are reset, this might clear up an error in the printing queue system that causes abnormally high CPU usage. 

Every printer has a different way to perform a factory reset; some require you to go to the printer’s settings via its built-in interface, while others require a simple prolonged holding of the power button. In any case, check your printer’s instruction manual online to find the specific steps to perform a factory reset.

After the reset is done, restart your devices, then open up your Windows task manager and check if the issue persists.
