Every change the application makes

All 122 changes, with the exact registry path or system setting for each. Published before you buy, not after.

What is this?

Every change JINSHI PC Tweaks can make to a machine, generated directly from the application's own definitions rather than written by hand. If the software would write a registry value, that value is in this table. Nothing is summarised as "system optimizations".

All 122 are individually reversible, and a System Restore Point is created before any of them is applied. 82 write registry values; the rest use power plan settings, service configuration, netsh, fsutil or boot configuration.

If you want to know what an individual Windows setting actually does before changing it, the settings reference documents the ones worth understanding properly, and this page covers widely-repeated tweaks that Microsoft's documentation shows do not work as claimed.

ChangeWhat it writesRisk
Apply Timer Resolution Requests Globally
