Winzip holds the zip file open

I often find that, when I select files and use the Explorer menu "WinZip/Add to somefile.zip", the somefile.zip remains opened by "some" process (Windows doesn't bother to tell you which one). Using ProcessExplorer doesn't help identifying the process.
The only workaround I found so far is restarting the Explorer.exe process.
Windows is a pathetic piece of piecemeal spaghetti disaster and WinZip is not better. I normally use 7Zip.

Notepad++ : all the accessories you need for it

Notepad++ is a really great tool, but you need a couple of plugins to make it a truly joyful war machine:
TextFX https://sourceforge.net/projects/npp-plugins/files/TextFX/
Xml Tools https://sourceforge.net/projects/npp-plugins/files/XML%20Tools/
They are both priceless!
For installation instructions, I leave you to google

The issue was solved changing JDK
