What is NMIndexStoreSvr.exe?

The genuine NMIndexStoreSvr.exe file is a software component of Nero Scout by Nero.
NMIndexStoreSvr.exe is an executable file that is part of Nero Scout, an indexing service that catalogues media files on the system. This program keeps track of changes made to files and folders on the computer and automatically indexes any new files. This is a critical component for Nero Scout and should not be directly removed. Nero Scout comes bundled with the Nero Suite. The program keeps a record of media files such as photos, videos and music files, making them faster to search. The indexing service has been known to slow down computers and many users choose to disable Nero Scout entirely. In the newer version of Windows, Microsoft has done away with indexing altogether making this program obsolete. Nero is a German software developer best known for their flagship disc burning software program, the Nero Suite. Richard Lesser founded the company in 1995 as Ahead Software GmbH but the company changed their name to Nero in 2005. Nero became quite popular after many OEMs (original equipment manufacturers) decided to bundle the suite with their hardware products. Nero is headquartered in Karlsruhe, Germany.

Nero scout is the problem. go to start programs nero7 nero product setup on the left you will see 'update, language, setup, license' Click Setup, on the right nero 7 will appear with 'modify and remove' options. You want to modify. A custom setup window will appear. Click tools and select 'this option will not be available'. Click nevt. now use regular windows Search on C:drive (or drive you installed it on) for 'NMIndex'. several files may appear but you want to RENAME NMIndexStoreSvr.exe,and NMIndexStoreSvrPS.dll by placing an underscore _ at the beginning of the name ie; _NMIndexStoreSvr.exe and _NMIndexStoreSvrPS.dll and thats it. I didnt even need to reboot and havent seen another error message
NMIndexStoreSvr.exe was creating a flashing temporary file lucene-9280b370d1038bf9b464c630bb1fed8c-commit.LOCK in my Temp folder. Because of quick disappearance and reappearance of this file, I coudn't use the Ctrl-A command to select all the files and press Shift-Del. So I started the Windows Task Manager in Windows 7 Basic OS and clicked on the Processes tab and found out that this file NMIndexStoreSvr.exe was using about 25% of my CPU sources and was creating the temporary file. I renamed this file to something else and the "lucene" file stopped appearing in my Temp folder. Good luck!

Can consume up to 99% of processor cycles. I classify as bloatware.

Will use up to 97% of cpu at times. The computer locks up. WinXP service pack 3. I would almost list it as malware but the intention is benign.
Eats resouces like mad. Is a longstanding Nero bug. I disabled it thru Settings Admin tools Services. It is listed as NMIndexing Service. Hope that will stop it. (Unchecking "Nero Scout" doesn't seem to stop Thanks to John for this....worked a treat my com speeded up straight away...Many thanks.

It's essentially useless to those of us who have no use for Nero Home and Startsmart, neither of which I installed. Indexes all your media files. Probably sends the info back to Ahead. More like Nero Snoop!
its harmless

I did not choose to install Scout, but the indexing service runs anyway. I disabled the service (services.msc, NMIndexingService) and ran this to unregister the DLL: regsvr32 /u "%COMMONPROGRAMFILES%\Ahead\Lib\MediaLibraryNSE.dll" (note that on the web page in the link below, the '\' are missing before \Ahead\Lib\Media...
