Wintoys, a tweak utility for Windows, can now turn off the background AI components that its developer says hold between 2GB and 8GB of RAM on Windows 11. Version 3.0 adds the switch under its Optimizations page, along with a new add-on that saves your settings as a file.
The service in question runs several copies of a process called WorkloadsSessionHost.exe. The memory goes to models Windows keeps resident for its AI features, and he says that happens whether or not you use them. On his own Surface Pro with 16GB of RAM, Bogdan Patraucean reports that memory use fell from 11GB to 5GB after switching it off.
Patraucean says in the 3.0 release post that the app also gets a new Artificial intelligence section with controls for features such as agentic search, Recall, Click to Do and Notepad’s writing tools. It only appears on PCs with an NPU, such as laptops with a Snapdragon or Panther Lake chip. If you do not see it, the PC has no NPU or no Notepad app, and there is nothing to switch off.
The profile feature is the most requested one since the app launched. It exports your current Windows settings to a small JSON file you can import later with one click, which helps when setting up a fresh install or a friend’s PC. A profile made on Windows 10 imports on Windows 11, and one from a Copilot+ PC imports on any other machine. Settings that do not apply are skipped. Profiles come with a Wintoys+ add-on, which is sold in the Microsoft Store and works on Windows 10, but a Store bug had to be fixed first. Microsoft’s fix reached only Windows 11, from build 26100.9278 (or 26200.9278) onward. A Windows 10 user has to buy the license on a Windows 11 machine first, and it then unlocks profiles on the older PC.
A new configuration mode also changes how settings are applied. Settings that Windows allows as policies now go through the Group Policy engine instead of the registry, so the Group Policy Editor shows what Wintoys set and Windows no longer overwrites it at its 90-minute sync. Nothing changes after the update until you apply the settings again.
The storage cleaner now shows drive C: usage with a progress bar at the top, and its scan includes hidden system files, so it may report more space to free than before. Pending settings that need an Explorer or system restart are listed in the order you changed them, with a counter in the navigation bar.
