Problems identified
To do this, search for "Adjust the appearance and performance of Windows" in the Windows search bar.
Click on the "Advanced" tab, then click on "Change" in the "Virtual Memory" section.
Check "Automatically manage paging file size for all drives", then click "Ok".
Finally, restart your computer.
Here are the details of the identified bad practices:
System modifications :
- The registry key LargeSystemCache has been modified.
This registry key is simply not used by Windows today.
In fact, this registry key was used by Windows XP and Windows Server 2003, but is no longer used since then.
Avoid following "optimization" tutorials that advise random things.
Link to the official Microsoft documentation regarding this registry key: available here.
Software / tools not recommended :
- The optimization software CCleaner claims to improve performance.
It modifies Windows settings, "cleans" the registry, deletes files, etc.
Depending on the options used in such software, they can create problems.
For registry cleaning, it is a myth; the registry does not need to be cleaned.
If they have a paid version, their goal is to make you buy it.
They are not actually useful, and you can simply uninstall these programs.
You can watch this video to learn more about best practices.
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.
If you want to delve deeper into the subject in general, you can check out this advice page for more explanations.
Optional considerations
To enable the RAM's XMP profile (also called DOCP or EXPO), please follow this tutorial.
Note: If you cannot find the option in the BIOS and your PC is an OEM brand (HP Omen, Dell, Lenovo, etc.), it is possible that the option is not available.
You can download the update from the Nvidia website.
Here is the list and size of the detected unallocated spaces:
- Storage 4: 2 TB
If you want to allocate these spaces to use them, you can do this:
- Right-click on the Windows icon at the bottom left of the screen > "Disk Management"
If an "Initialize Disk" window appears:
- Leave the default options (GPT partition), then click "OK"
Otherwise:
- Identify the unallocated areas (they are in black)
- Check on the left if the storage indicates "not initialized" instead of "online". If so, right-click on it > "Initialize"
- Then, right-click on the unallocated area (in black) > "New Simple Volume"
- In the wizard, you can leave all the default options. Click "Next" until the end, then "Finish"
- You can now use this space

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

Few motherboards have this sensor.34°C / 51°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.F60e (2020-12-09)
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).Inactive
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.14s

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.Active
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.3d 2h
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
