My usual disclaimer: I'm not an expert at anything.
The lpremove.exe removes language packs that are not needed. So in my opinion only, it doesn't seem to be a critical file. As far as the rest of the corrupted/damaged files shown in your attached sfcdetails.txt, that's another story.
There are some folks here on the Forum who are experts in deciphering and repairing system files by extracting fresh copies from the installation disk. I'm not one of them. Because of my lack of expertise in this area, I usually recommend a repair install. This should fix your currently installed Windows 7 and preserve your user accounts, data, programs, system drivers, etc and take less than an hour to accomplish. The most time consuming part of the repair is reinstalling Windows Updates.
(Which I recommend doing manually and not automatically. Start with the critical updates, then the important, and finally the optional. Keep track of the KB numbers. Install just a few at a time, reboot after each group, and make sure your computer is working OK. If any update causes a problem, you'll know which group to uninstall. Then install one update at a time and reboot after each one. They'll either all install and you can go to the next group, or you'll know which specific update is at fault. Save it for last and go on with the next group.)
And no offense intended to you or any one else who may prefer installing individual files. Repair Install
