Workaround when Sakura Editor starts up slowly

to japanese

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.

Explanation of terms
phrase	Explanation
Windows Defender	Security solution attached to Windows 10
Antimalware Service Executable	Windows Defender process
sakura.exe	Executable file of Sakura Editor
MsMpEng.exe	Windows Defender executable Microsoft Security Essentials executable

Workaround

Exclude sakura.exe from the monitoring targets of Windows Defender.

1. Start Windows Defender Security Center

Startup method 1

Click ∨ on the taskbar and click the Windows Defender icon.

Startup method 2

Start Menu> Settings> Update & Security> Windows Defender> "Open Windows Defender Security Center"

4. Exclusions-Adding or removing exclusions

Transcription

Windows Defender Antivirus does not scan the excluded items. Excluded items may include threats that can make your device vulnerable.

5. Add exclusions

If there is a program whose startup is slow other than sakura.exe, add it here. Symptoms may improve.

Click Add Exclusion and select "File" from the drop-down list to select the program to exclude (sakura.exe this time).

UAC (User Account Control) will be displayed. Click “OK”.

6. End of procedure

Sakura Editor startup time has been reduced from 18 seconds to 0.5 seconds.

Summary

If you feel that the Sakura Editor starts up slowly...

Start Windows Defender
Open "Virus and threat protection settings"
Exclude sakura.exe
End of procedure
