Question:

I have modified some registry values under “Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games” following a video tutorial that claimed to improve gaming performance. However, I realized that this could be risky and I want to undo the changes. What are the original default values for this registry key? I have not restarted my computer yet. The video I watched is [here].

Some additional tips for rephrasing questions are:

– Use clear and specific terms that describe what you want to know or do.

– If possible, cite the source of your information or the reason for your inquiry.

Answer:

If you are a PC gamer, you might have come across some online tutorials that claim to boost your gaming performance by tweaking some registry values. However, not all of these tutorials are reliable or safe, and some of them might even damage your system or cause instability. In this article, we will show you how to restore the original default values for a registry key that is commonly modified by these tutorials, and how to avoid such problems in the future.

What is the Registry Key in Question?

The registry key that we are talking about is located at:

`Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games`

This key contains several values that affect how Windows allocates resources for gaming applications. Some of the values are:

• `Affinity` – Determines which CPU cores are used for gaming.
• `Background Only` – Determines whether gaming applications run in the background or not.
• `Clock Rate` – Determines the base priority of gaming applications.
• `GPU Priority` – Determines the priority of GPU usage for gaming applications.
• `Priority` – Determines the priority of CPU usage for gaming applications.
• `Scheduling Category` – Determines the scheduling policy for gaming applications.

Some tutorials suggest changing these values to higher numbers or different settings, hoping to improve gaming performance. However, these changes might not have the desired effect, or might even worsen the performance or stability of your system. Therefore, it is advisable to restore these values to their original defaults, unless you know exactly what you are doing.

How to Restore the Default Values?

If you have followed a tutorial that modified these values, and you want to undo the changes, you have two options:

• Option 1: Use System Restore
• Option 2: Use Regedit

Option 1: Use System Restore

System Restore is a feature that allows you to revert your system to a previous state, including the registry. If you have created a restore point before following the tutorial, or if Windows has created one automatically, you can use this option to restore the default values for the registry key.

To use System Restore, follow these steps:

1. Open the Start menu and type “create a restore point”. Click on the result that appears.

2. In the System Properties window, click on the System Restore button.

3. In the System Restore window, click on Next.

4. Select a restore point that was created before you followed the tutorial, and click on Next.

5. Review the changes that will be made, and click on Finish.

6. Wait for the system to restore, and restart your computer.

Option 2: Use Regedit

Regedit is a tool that allows you to edit the registry directly. If you do not have a restore point, or if you prefer to manually restore the default values, you can use this option. However, be careful when using Regedit, as making a mistake might cause serious problems for your system.

To use Regedit, follow these steps:

1. Open the Start menu and type “regedit”. Click on the result that appears.

2. In the Regedit window, navigate to the following key:

`Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Games`

3. Right-click on the key and select Export. Save the file somewhere as a backup, in case you need to restore it later.

4. Double-click on each value and change it to the default setting, according to the table below:

Value | Default

— | —

Affinity | 0

Background Only | False

Clock Rate | 10000

GPU Priority | 8

Priority | 2

Scheduling Category | High

5. Close Regedit and restart your computer.

How to Avoid Such Problems in the Future?

To avoid such problems in the future, you should be careful when following online tutorials that suggest modifying the registry. Here are some tips to keep in mind:

• Always backup your registry before making any changes, either by using System Restore or by exporting the key that you are going to modify.
• Always research the source and the credibility of the tutorial, and check the comments or reviews from other users who have tried it.
• Always understand what the changes are supposed to do, and what the potential risks or side effects are.
• Always test the changes on a single game or application, and monitor the performance and stability of your system.
• Always revert the changes if you notice any problems or no improvement.
