Introducing SysGreen 0.21.0
The first public release of SysGreen — a Windows desktop tool that reclaims startup RAM by safely and reversibly disabling the things that auto-start and sit resident after boot.
Every fresh Windows install boots fast. Then, over months, it doesn't. App updaters, chat clients, OEM utilities, telemetry, "helper" processes — each one quietly adds itself to startup, and each one claims a slice of RAM that never comes back until you reboot. Most people never notice the individual additions; they just notice that the machine got heavier.
SysGreen 0.21.0 is the first public release of a tool that does something about that — carefully.
What it does
SysGreen is a Windows desktop "footprint manager." It enumerates everything that auto-starts — Run keys, Startup folders, logon scheduled tasks, and UWP background apps — figures out what each item is and how risky it is to disable, and recommends the safe wins. Then it lets you disable them and undo every change.
It is deliberately not a "RAM cleaner" or a "booster." It doesn't free memory by force; it reduces what loads in the first place, and it tells you the truth about what it can and can't promise.
Safe is the whole point
Disabling a startup entry should never be a leap of faith:
- Nothing is ever deleted. SysGreen flips Windows' own native disable flags, so every change is reversible by construction.
- A System Restore Point is created before any batch that touches boot-relevant items.
- Full history with one-click undo — every change you make is recorded and can be reversed.
- Nothing is auto-applied. SysGreen recommends; you click Apply.
A curated, offline Knowledge Base classifies each item by Purpose and Safety, and anything it can't confidently identify defaults to Caution and is never recommended for disabling.
Self-updating, no runtime required
0.21.0 ships as a single self-contained installer (the .NET runtime is embedded — you don't install anything else), and it updates itself going forward. It installs per-user, so there's no admin prompt just to install.
Get it
Head to the Downloads page and grab the installer, or read the full changelog. The binaries aren't code-signed yet — code signing through the SignPath Foundation open-source program is in progress — so SmartScreen may warn "Unknown publisher"; choose More info → Run anyway.
SysGreen is open source under Apache-2.0. Issues, ideas, and contributions are welcome on GitHub.
