Memory leaks are caused by runSW.exe which launches SwUSB.exe.
Since the above mentions is from Realtek, I can safely say this SwUSB.exe is part of RtWLan.exe or "REALTEK 11n USB Wireless LAN Utility" from the Alfa Network AWUS036NHRv2, it comes once you install the drivers for this WLAN Utility.

Found this little gremling hiding in my Programs after installing a Driver Updater (Smart Driver Updater) that was not a legit copy (embarrassed smiley) I deleted it due to the fact it could be recording key strokes and other private data. I shall follow all of the tools instructions given here. Thanks so much Mark

As of 9/10/2015 they seem to have fixed the memory leak but SwUSB.exe still has a bad handle leak. Use Task Manager to show handles (configure columns displayed) and watch for a minute.
all i know is that SwUSB prevents windows 10 from shut down at times as it cant end the process they need to find a fix for it!

I can confirm what Chris said: Memory leaks are caused by runSW.exe which launches SwUSB.exe. This couses huge memory leak in modified memory on WIN7, and when you kill runSW.exe, modified memory drops drasticly.
Came with my wifi adapter drivers.
I am unsure if this is related to the RunSW.log though it seems likely because that log includes the instances when SwUSB.exe was launched. This log on my system reached over 1.5 GB! In a roundabout way this can really mess up your system. Deleting the .log file had no negative effect but after only 1 day it is already up to 50 MB again.

Best practices for resolving SwUSB issues

A clean and tidy computer is the key requirement for avoiding problems with SwUSB. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the SwUSB.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
