<![CDATA[Windows 11 constantly crashing when having NP++ installed]]>Hi all,
I like NP++ very much but I’m a little bit annoyed because it crashes my Windows 11 explorer every time I try to run the CMD, PowerShell or Eventmgr.
I read about the nppshell.dll issue in some older versions of 2025. But I keep updating NP++. Even with version 8.9.8.1 this issue happens.

The ONLY thing that helps is to rename the file C:\Program Files\Notepad++\contextMenu\NppShell.dll .

I wonder if I’m the only one experiencing this issue.

Thank you in advance for support.

Best regards,
Seb
