What Is Greenshot?
Greenshot is a lightweight screenshot app for Windows. It lets you capture the full screen, a window, or a selected region, then save, copy, annotate, or send the image to other apps.
On many PCs, Greenshot runs in the notification area so its hotkeys are always ready. That is why some setups add it to startup. If you use keyboard shortcuts for screenshots throughout the day, leaving it running can be convenient.
Is It Safe?
Yes — Greenshot from the publisher Greenshot is generally safe. It is a well-known screenshot tool, not a Windows component or security feature.
As with any app, you should still confirm that the file is the real one if something seems off. In Task Manager, right-click greenshot.exe and open its file location. A normal install is often under Program Files or your user profile's app folders, not inside random temporary folders. You can also check the file's Properties and review its Digital Signatures tab if present.
If a file named greenshot.exe is using unusual amounts of CPU, relaunching itself repeatedly, or running from an unexpected location, treat that as suspicious and investigate further.
Should I Disable It at Startup?
Usually, yes — if you do not need instant screenshot hotkeys after every sign-in.
Disabling Greenshot at startup is generally safe. The app should still work normally when you open it manually. The main thing you lose is background availability for tray access and global capture shortcuts until you launch it again.
Keep it enabled if you rely on it constantly for work, support, documentation, or bug reporting. Otherwise, it is a reasonable startup item to turn off.
Why Is It Using High CPU or Memory?
Greenshot normally uses very little CPU and memory while idle. Short spikes can happen when it captures a screen, opens the editor, processes a large image, or exports to another app.
If usage stays high, common causes include:
- a stuck screenshot or export action
- a conflict with another overlay, capture, or clipboard tool
- repeated hotkey triggers
- a damaged install or settings issue
If it keeps consuming resources, close and reopen it. If that does not help, update or reinstall Greenshot. If you rarely use it, disabling startup is a simple way to stop background usage.
How to Disable or Remove It
If Greenshot appears in Task Manager > Startup apps, you can disable it there. It may also have its own setting to start with Windows, though the exact wording can vary by version.
To remove it completely, uninstall Greenshot from Settings > Apps on Windows. If you only want to stop it from loading automatically, disable the startup entry instead of uninstalling.
Do not delete program files by hand unless the normal uninstall fails.
Where Kudu Helps
Kudu can show whether Greenshot is set to launch at sign-in and let you disable or remove the startup entry. On Windows, Startup Manager checks common startup locations such as Run entries, the Startup folder, and Task Scheduler.
If greenshot.exe is using too much CPU or memory, Kudu's Performance Monitor can confirm the process, show its PID, and help you see whether it is actually the app causing the load. If needed, you can end the process and then relaunch Greenshot manually.
If a suspicious greenshot.exe is running from an odd location, Kudu's Malware Scanner can help check for persistence and other signs that it is not the real app.
Frequently asked questions
- Can I disable Greenshot without uninstalling it?
- Yes. Disabling its startup entry only stops it from launching automatically when you sign in. You can still open Greenshot manually whenever you need it.
- Will disabling Greenshot break Windows screenshots?
- No. Windows has its own screenshot features. Disabling Greenshot only affects Greenshot's own background hotkeys and tray behavior until you launch it.
- Is greenshot.exe a system process?
- No. It is a third-party screenshot app, not part of Windows. That means it is safe to turn off at startup if you do not need it always running.
