Yes, I got “bitten” by this bug too 
If you google for “Windows 7 Explorer Refresh Bug”, you’ll get the picture. The problem seems to be very wide-spread. I, too, read many posts and tried different suggested solutions. In my case they just did not help.
The way I solved this issue on my PC (Windows 7 x64 Professional) was by deleting “Network Location” entries to places that are no longer accessible.
On the above picture you can see that at some point I added two Network Location items to shares on the machine with IP address 192.168.2.3, the machine was on line at the time. Later, this machine went off-line and this caused Explorer not to refresh itself when folders were modified – created, deleted or re-named.
After I deleted the inaccessible locations, logged off and logged in, the problem got resolved.
Hope it will help somebody else.

Thanks go to SoonerAl and his post on dslreports site that I hit when searching for a solution.
I was syncing some data between my main machine Server 2003 x64 and Windows 7 x64 on my laptop using SyncBackSE. After the sync finished the log displayed plenty of errors. I checked Windows 7 event log – quite a few errors
“The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.”
SyncBackSE, the program I use, was just copying my Dev directory to Win 7 laptop, yet Win 7 seemed to be “choking”.
A quick search brought me to a good post describing that Win 7 “needs to be told that it can act as a server” by changing a Registry setting.

I think the author was too nice Win 7 acts as a server out of the box, after all it allows you to share its resources. Perhaps in the pursuit for more “efficient” OS, the OS vendor decided to reduce the amount of resources allocated to “real needs” in favour of allocating them to “fancy things” like “aero desktop” and some media features?

Virtua Win - this is a very fast and reliable virtual desktop application for Windows. It is self-contained, so you don’t even need to install it. I just love it! I used an old Microdoft virtual desktop utility and it just kept crashing. Virtua Win haven’t crashed once.
I had the following error when copying a large file from Server 2003 64-bit SP2 to a VMWare client Server 2003 SP1
“The server has detected an attempted Denial-Of-Service attack from client …”
It popped up on the machine the file was being copied from.
The way to fix it was to disable DOS Detection option in the Registry.
