I've been using Notepad++ for years now. Since a short while, Notepad++ doesn't start anymore (maybe since a recent Windows Update? Or maybe a plugin update?). The process shows up in the task manager, but it seems to stop executing with a consumed CPU time of less than a second.
However, after re-installing it (V6.9.2) (and also trying the previous version 6.9.1, same effect), I noticed that it does start as usual when executed as Administrator. Note: The behavior is different than the question "NotePad++ only runs as Administrator or not at all" - in that case notepad++ requests Admin rights when started, in my case it doesn't start at all.
I also tried to start it without plugins using the -noPlugins command line option. No effect.
Any idea what could be the cause? What else could I try to reset?
