0_0 I can see it's fully hidden but dam what would happen if I decided to temporarily disable the service so I could play my games correctly??? I would hate to have a game slacker purposely installed by M$ to ruin my high speed Vista performances. On a side-note. Most my games don't seem to play right atm so maybe that's a solution? xD

If you have pirate Vista or Windows 7, it is activation/genuine crack, so if you have pirate Vista or Pirate Windows 7, dont delete it   Ville
It's a required system process. Windows will shut itself off if it is terminated from inside task manager. It's growth in memory usage occurs from continous use of WMP 11  See also: Link   BcB9000
Local Session Manager. Process found on Windows Vista and whose role is to manage the terminal server connections to the machine. In Vista, terminal server sessions are not just Remote Desktop sessions from remote users as they are in Windows XP/2003, they are also your sessions when you are logged in to the PC at the PC itself, as all sessions, whether local or remote, are virtualised terminal server sessions. It follows, therefore, that this process is a crucial core process of Windows Vista.  See also: Link   Johnny Johansen

it was using my entire processor 0_0  
Had a version in C:\Users\ user \AppData\Roaming that was using 99% cpu from start. Stopped and deleted, no ill effects.   nix
It made my processor go 100% constantly, and made my pc very slow.   Jimmie
This virus was named after the critical file on Windows, but was placed in AppData instead of System32. I noticed it had been running at startup, but my pc was too fast to be able to see the little line of text when it came by. This is a trojan hidden Bitcoin miner, as wierd as it sounds. GET RID OF IT GOOD LORD. Make sure it's in AppData though. If you delete the System32 one, you're screwed.   Evan Klug
It has very bad memory leaks but a way to fix it sort of is by going to task manager and right clicking lsm.exe and change affinity and change it so it only uses 1 so it takes less processing power, All though it will not fix any ram problems it gives, And also DO NOT DELETE IT.   vgaggia
I found it in appdata/roaming i deleted it and my computer works fine   Jacob Collins
lsm is supposed to reside within the Windows folder. If you find it outside that (e.g.in a user profile), that's something masquerading as the real lsm   anon user
Critical Win7 file. Ism.exe 32* isn't.   Eppo
