I just noticed something else that's screwy: When other people upload files from me, they usually don't get 100%, and quite often they get cut off because "upload limit is reached". BUT: I set the upload limit per person at 300! So I doubt they've reached it, and I wonder why they don't get 100% of my files. I'm sure this is somehow related to my problem with finding very few search results.

I tried getting a fixed IP address, but then couldn't get LW or internet to work. I'll look into this further to see what I did wrong, but that was scary for me...

This can be related to your overall upload slots with LW 4. Thus per person might be set to 300 per person but if the overall upload slots is 5 for example & there are lots of people trying to get a spot in your uploads then eventually you may see that message. Or vice-versa, lots of upload slots but only a couple per person when they try to download many from you. I occasionally even see Banned Greedy Client when they've tried to download 100's or even 1000's of files from me at once lmao (this only bans them for that session & still some in the queue may continue at some stage.)

People's downloads from you stopping might be due to a number of reasons. For example, someone else uploading from you steals most of the bandwidth leaving little or zero for one or two others. I see that happening frequently. I wish there was something I could do about it but unfortunately not. I also noticed LW 5 uploaders tending to stop more frequently than LW 4 users uploading from me whilst I'm using LW 4.

I have no idea about those files you mentioned in the previous post. Try a google for searchindexer. A couple articles suggested it belongs to Vista. Here's one article searchindexer.exe utilizing near 100% CPU usage; suggestions from this forum tried to no avail and another File Information - How to remove SearchIndexer.exe error problem
