How to Modify the Windows Registry.

[FinneasFernandez]

Hello. Recently, I successfully made my first Windows registry modification to resolve an annoyance. To ensure I don't create any issues in the future, I'm seeking guidance. Currently, we have three PCs in use. One of them has only one Local Admin Account without a Standard User Account. Following a tutorial, I made a modification to the HKEY_CURRENT_USER key, and it worked smoothly.

On the other hand, our other two PCs, operating on Windows 11 22H2, have both a Local non-Microsoft Admin Account and a Standard Local User Account. The registry keys displayed in regedit are the typical ones: HKEY_CLASSES_ROOT, HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_USERS, and HKEY_CURRENT_CONFIG.

If I wish to implement a change in the registry that applies to both the Admin and Standard User accounts, should I make modifications within the HKEY_LOCAL_MACHINE key instead of CURRENT_USER, as I did with the PC that only has one account? Additionally, I want to mention that I created a backup of the Registry before proceeding with any modifications.

I would appreciate any advice to ensure I'm following the correct approach. Thank you.

Avoid making changes unless you absolutely need to resolve a specific issue or update a setting. When adjusting settings specific to your user account, always use the HKEY_CURRENT_USER branch.
