Problem identified
Here are the details of the identified bad practices:
System modifications :
- The registry key SvchostSplitThresholdInKB has been modified.
System services are now grouped together instead of being separated.
It is not recommended to change the default behavior as it can impact system stability in some cases (if a service crashes, it can affect other services in the same group, potentially causing a blue screen CRITICAL_PROCESS_DIED or SYSTEM_SERVICE_EXCEPTION).
What to do about these bad practices? :
- This is not really ideal (but not the end of the world either).
Windows seems to have been modified by software/scripts or manually.
If you know how to correctly revert these settings to default, you can do so.
However, note that UserDiag does not detect all possible modifications.
You might be missing other system settings that have been changed.
There may be only a few modifications detected above, but potentially other things could have been altered.
If you have issues or if you prefer, you can always reinstall Windows properly via this tutorial.

Optional considerations
You can download the update from the Nvidia website.
You can update:
- Via Windows Update. (if available)
- Or via the Windows 11 Installation Assistant. (the tool will update Windows without affecting your personal files)

VRM temperatures min/max >VRM temperatures min/maxThe VRMs (Voltage Regulator Modules) are the power stages located on the motherboard near the processor.
High temperatures can be a sign of:
- insufficient VRM cooling
- processor too demanding for this motherboard
- aggressive overclocking
Note:
Few motherboards have this sensor.32°C / 37°C

Version >VersionThe BIOS version and date help identify the currently installed BIOS version on the machine.
Notes:
- Sometimes, the retrieved BIOS version may slightly differ from the one displayed on the manufacturer's website.
Example: With an MSI BIOS, the retrieved version might be '2.B0' while on the website, the version is listed as '7D22v2B'.
- The retrieved BIOS date may also slightly differ by a few days/months from the one displayed on the manufacturer's website.
Example: With an MSI BIOS, the retrieved date is 26/01/2024, while on the website, the date is 07/01/2023.
Here, the date on the website corresponds to the upload date, while the retrieved date is the BIOS creation date.1512 (2025-06-05)
Boot mode >Boot modeBoot mode of the computer:
- Legacy (old mode)
- UEFI (recent mode)UEFI
TPM >TPMThe TPM is a component (physical module on the motherboard or emulated by the processor) that allows secure storage of information.
Specifically, it can store encryption keys, certificates, biometric data, etc.
For example, it is used to encrypt storage with BitLocker or unlock the computer with Windows Hello.
Some anti-cheat software for video games can also use it to confirm the integrity of the game and the system.Active
Secure Boot >Secure BootThis is a security option available in the BIOS.
Secure Boot ensures that the computer boots only with a verified operating system.
This setting may be required by some game anti-cheats (Valorant, FIFA).Active
Boot duration >Boot durationBoot duration is the time elapsed between pressing the power button and the motherboard returning POST OK (successful hardware check).
This can be useful for identifying a slow boot issue.
(long memory training in DDR5, for example).
A boot duration of around ten seconds is normal.
Note that this period occurs before Windows starts.
Applications that launch at Windows startup do not affect this duration.17s

Fast startup >Fast startupWindows Fast startup allows older computers to boot faster.
Sometimes this mode (enabled by default) can be the source of issues such as LEDs staying on, or crashes at startup with incompatible drivers.Inactive
Uptime >UptimeUptime is the time elapsed since the last Windows startup.
This information can be useful to determine how long it has been since Windows was last restarted.
Note that if Fast Startup is enabled in Windows settings, shutting down the computer will actually put it into a hibernation state.
Therefore, Windows only fully shuts down during a restart.
(by clicking on restart and not on shutdown)
As a result, you may sometimes observe high uptimes of several days, even if the computer is regularly shut down and turned on.
However, if Fast Startup is disabled, the computer will fully shut down during shutdown, and the uptime will be reset with each startup.5min
VBS >VBSVirtualization-Based Security (VBS) is a security feature in Windows.
Its purpose is to protect certain parts of Windows by isolating them from the rest. It may be enabled by default on compatible Windows 11 installations.
It can also be activated if core integrity in Windows Defender is enabled, when using WSL2, or other virtual machine-related features.
However, this feature may slightly reduce performance when enabled.
This option only protects against certain complex vulnerabilities. It will not protect you from a cryptocurrency miner or password theft, etc.
Microsoft advises gamers, if they wish, to disable this option. (More information)Inactive
Antivirus >AntivirusCurrently active antivirus on your computer.
Ideally, it is better to use something like Windows Defender, which is relatively effective and already integrated by default in Windows, or use a third-party antivirus of your choice.
However, it is advisable to avoid less recommended antiviruses like Avast, Norton, McAfee, Iobit, etc., which are known for collecting your personal data rather than protecting you.Windows Defender
