The Dell Wireless WLAN Tray Service is useless bloatware and should be disabled. More info: y42k.wordpress.com/.../todays-tech-tip-kill-dells-wirelesss-wlan-tray-service
I have upgraded my Dell XPS M1530 laptop to Window 7 and have encountered a memory leak that renders my OS inoperable in a matter of a few hours despite having 4GB of RAM. I'm "losing" almost 1MB of RAM every couple of seconds. After doing some Google searching, I have discovered the very source of this huge leak is the bcmwltry.exe which is associated with the Dell Wireless WLAN Card Network Controller. I'm running version 5.10.38.30 of this executable which came with this several month old laptop, running x64 Windows 7 Home Premium. To demonstrate the leak, open the Windows task manager.Click the processes tabClick the "Show processes from all users" checkbox at the bottom.Under the view menu, click Select Columns, and select all the Memory options as well as Page Faults.Click OK to see the new columns and then click Page Faults to sort the processes by page faults. For all my programs, this number of page faults is near zero and or static, with the exception of bcmwltry.exe which has some 10,000+ faults PER SECOND!!!! There's definitely a huge memory allocation problem that's causing this to spiral out of control. There are currently over 14 MILLION faults having only spawned this .exe about 15 minutes ago. Wowsers. OEM02MON.exe associated with the Dell Live! Webcam tray control also appears to have a similar problem. Would like some immediate resolution here. Rebooting does not help, and these problems occur in the absence of any other applications running.  Thanks in advance,Evan
