Sakura Editor is a Japanese text editor that runs on Windows.

[Characteristic]
  • A free text editor
  • Adopts SDI method that opens a window for each document
  • When the tab bar setting is ON, it operates as a tab type editor.

That's all for the Sakura Editor.

SDI: Single Document Interface

Well, the main subject.

After upgrading from Windows 7 to Windows 10, Sakura Editor now takes 18 seconds to start.

I felt 18 seconds was an abnormal value, so I googled it as usual.

As conclusion,

It was Windows Defender that came with Windows 10 that prevented Sakura Editor from starting.

Now that I know how to set up Windows Defender, I'll share the steps I performed.


The cause is Windows Defender

Since Antimalware Service Executable was monitoring sakura.exe, the start of Sakura Editor was delayed.

Antimalware Service Executable is a Windows Defender process whose executable is MsMpEng.exe.

Windows Defender is a security solution that comes with Windows 10.

The Microsoft Security Essentials executable file that Microsoft provides free of charge for Windows 7 is also MsMpEng.exe.
