Probably all Windows System Admins know the name 'SysInternals' very well, mostly because of their free set of Windows Utilities called 'Winternals'. They have just released the new version: PsTools v2.14.
The guy behind the creation of these tools is Mark Russinovich. I have recently used his Registry Monitoring Tool (Regmon v.7) to see what was going on on my system following Mark's blog on MSN Desktop Search Tool.
I found out that 'Hello', which is an IM that was recently bought by Google and is a convenient application currently you can use to post a picture to blogger, was non-stop polling the registry 10s of times in a second filling all the monitor screen...
I killed it and then started it up again. Apparently it is trying to communicate with Picasa -yet another cool imaging tool Google purchased recently- related registry keys. Whatever the reason is, I derive from Mark's blog entry that Hello is ayet another badly written application. So, instead of keeping it minimized in the tray when I am not using it, I will just terminate it. I suggest you do the same.
