What’s new
Verified 3h ago# System Informer 4.0
The first 4.0 release: a new kernel/user transport, a Process Monitor, Hybrid Analysis integration, a JSON settings store, a rewritten installer, and a year of fixes across the app, driver, plugins, and phnt headers.
## Highlights
- Process Monitor (Tools menu): a driver-backed live log of process, thread, image, registry, file, handle and silo events with filtering, access-mask decoding, and configurable look-back.
- Hybrid Analysis integration (OnlineChecks): System Informer can now automatically check running processes and loaded images against Hybrid Analysis, showing verdicts directly in the process and module lists via a new Hybrid Analysis column. Unknown files can optionally be submitted for analysis. Results are cached locally so repeated lookups are free, and scanning is opt-in with per-service API keys, path exclusions, and rate handling built in.
- Ring-buffer informer transport in the kernel driver: large shared-memory ring instead of per-message port round-trips, with rate limiting and per-client statistics; informer callbacks run at APC/DPC level where possible.
- New installer: modern wizard with dark mode, DPI scaling, uninstaller,
