Using uTorrent in Windows 7 gave me no problems at all. My utorrent is almost always running
There are 2 approaches that I personally use on my system which can be combined or used independently;
1. Use Advanced System Care from IObit. It's system optimization tweaks your registry depending on your preferences which can be downloaded here
. No manual registry tweaks needed
2. For P2P connections, i use the Half-Limit fix and set it to 100 as it's limit. Information on what this patch does and download info is available here
Note: Before using the Half-Limit fix, be sure that it's not a seeding or firewall issue, uTorrent Home/Forum contains all the help available to resolve and answer these issues.
I'd recommend doing the patch if your utorrent/torrent download speeds are not being fully utilized (i.e. 1Mbps connection but only downlaoding at half the speed). Increasing the half-limit imposed by windows usually solves this issue.
Let us know how it works out. Cheers!
