Restarting Aero Glass in Win7

Posted by essjae on August 30, 2010

I was sure I blogged this before, but I can’t find it here.

Occassionally, after disconnecting with TeamViewer, Win7 doesn’t want to reenable Aero Glass.  Usually, I just switch themes and it back, but that will also fail to work at times. 

Running an admin console using the following commands to get Aero Glass working correctly:

net stop uxsms
net start uxsms

Android 2.2 (Froyo) issues

Posted by essjae on August 25, 2010

Well, it seems that there are some issues with Froyo.  After my automatic update it seems that at random times my GMail accounts stop updating (not good since we use Google Apps at my company), I don’t get notifications for voicemails and my text messages don’t appear until after I power-cycle.

I am having flashbacks to my last WinMo phone

Slow Windows VPC Networking speed/access to hard drive

Posted by essjae on August 8, 2010

This is a little old, but it still pops up from time to time.

If you’re having network speed issues, VPC Genius Bob Comer has the fix:

The problem is TCP Offloading and Windows VPC not getting along, here’s how to work around the problem by turning off offloading:
 
 
The fix is to edit the registry, use at your own risk and only if you are comfortable with editing the registry!

To turn off TCP Offloading, add a DWORD value in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters

label it  DisableTaskOffload , and change the value to 1, then reboot.
