A process called NMIndexStoreSvr.exe was creating the lucene-9280b370d1038bf9b464c630bb1fed8c-commit.LOCK file in my Temp folder.
NMIndexStoreSvr.exe is a Nero Home process and seems to be unnecessary for any functionality. Because of quick flashing of this file, I couldn't use the Ctrl+A command to select all the files and press Shift+Del.
So I started the Windows Task Manager, went to the Processes tab and found out that the NMIndexStoreSvr.exe process was using about 25% of my CPU resource and was creating the lucene temporary file.
When I killed the NMIndexStoreSvr.exe process the lucene file stopped appearing in my Temp folder.
The NMIndexStoreSvr.exe file was located (at least for me) in the following folder:
C:\Program Files(x86)\Common Files\Ahead\Lib\NMIndexStoreSvr.exe
To find the file, open Task Manager, click on the Processes tab, right-click on the NMIndexStoreSvr.exe process and select the "Open File Location" option which will take you directly to where the .exe file is located.
I renamed this file to something else and the lucene file stopped appearing in my Temp folder.
