explorer slow to launch applications

Explorer Problem, very slow to launch applications if LAN connection is
active

Windows Explorer, on doubleclick on any file, takes about 7 seconds to
launch the associated application, then another 2 seconds to open the
file.

I've checked in task manager, no apps are draining the CPU ressources
when exlorer hangs on the launch. All apps are responding that way.
Opening the context menue with a right-click on a file needs 7 seconds too.

If I start let's say, Word or Excel, the apps load right away.
Then I go in File/Open and open a file. The file opens immediately.

The setup:

P4 - 3GHz, 1 GB RAM
WinXP Pro SP2
PCI Ethernet adapter linked to Internet / LAN by a Zyxel 650HW
(ADSL-Router/Switch).

There is a network activity in the app-launching time: LAN Connection status
shows
Activity. 12 packets sent.
If the other network computer is running, time to launch an application is
75 seconds.
It doesn't matter if the Internet Firewall / Symantec Personal Firewall are
activated or not.

However, deactivating the LAN connection results in an immediate launching
the apps.

SysInternals FileMonitor shows QUERY INFORMATION for every application
installed on my system.
Here a very small section as an example, during launching Winamp.exe by
doubleclicking an *.ogg file:
....

Are there any suggestions what to do?

Hi Ramesh,

Thanks for your answer. I run RegScanner, looking for "\\" in HKRC,
but I found no entries pointing to a file/application in the other network
computer. Besides, if the network computer is running, application
launching time is even much longer. Only deactivating the LAN connection
helps.
Here a small section of a RegScanner result (scanning for "shell\open").
Entries for other apps are of the same pattern.

My applications are installed in C:\Programme\, and the registry entries

I don't understand why the explorer seems to look for the associated
application in another place, The launching problem occcurs on
doubleclicking any file, not
just with a specific application.

Thanks for your help.

Search the HKCU as well, just in case. If not, ShellExView might help.

Hi Ramesh

You solved my explorer problem! Applications are opened without delay
on doubleclick, the context menus unfold immediately.

I scanned HKCU for "\\" with RegScanner. I found some entries
pointing to a network computer, one of them indicating an application
KOOLMOVES. I deinstalled Koolmoves and erased remaining Koolmoves
registry entries.

Thank you so much!

Hi Ramesh

As I wrote in my last mail, I erased all registry entries
containing the word "Koolmoves", so I can only post you my
registry backup. #4 shows \\Nyllw, the name of the other
network computer. I vaguely remember trying to open the
Koolmoves application by the LAN at Nyllw (Win98) a year ago, without
installing
it at UliXP (WinXP), but that failed. In the end I had two instances
of Koolmoves installed at UliXP.


Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE]

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE\shell]

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE\shell\open]

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE\shell\open\command]
@="\\\\Nyllw\\KOOLMOVES V2\\KOOLMO~1.EXE \"%1\""



Another registry entry I threw out:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Map
Network Drive MRU]
"a"="\\\\Nyllw\\MELODY"
"MRUList"="ba"
"b"="\\\\Nyllw\\VBS BEISPIEL"


I still don't understand why, as an example, doubleclicking on a *.txt
file needed 7 seconds launching the editor, with mistakes in the registry
for completely different applications like Koolmoves or Melody or VBS
Beispiel.


Again, thanks a lot for your help.

registry backup. #4 shows \\Nyllw, the name of the other
network computer. I vaguely remember trying to open the
Koolmoves application by the LAN at Nyllw (Win98) a year ago, without
installing
it at UliXP (WinXP), but that failed. In the end I had two instances
of Koolmoves installed at UliXP.


Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE]

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE\shell]

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE\shell\open]

[HKEY_CLASSES_ROOT\Applications\KOOLMO~1.EXE\shell\open\command]
@="\\\\Nyllw\\KOOLMOVES V2\\KOOLMO~1.EXE \"%1\""



Another registry entry I threw out:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Map
Network Drive MRU]
"a"="\\\\Nyllw\\MELODY"
"MRUList"="ba"
"b"="\\\\Nyllw\\VBS BEISPIEL"


I still don't understand why, as an example, doubleclicking on a *.txt
file needed 7 seconds launching the editor, with mistakes in the registry
for completely different applications like Koolmoves or Melody or VBS
Beispiel.


Again, thanks a lot for your help.

Hi Ramesh

You solved my explorer problem! Applications are opened without delay
on doubleclick, the context menus unfold immediately.

I scanned HKCU for "\\" with RegScanner. I found some entries
pointing to a network computer, one of them indicating an application
KOOLMOVES. I deinstalled Koolmoves and erased remaining Koolmoves
registry entries.

Thank you so much!



Hi Stefan,

Search the HKCU as well, just in case. If not, ShellExView might help.

Hi Ramesh,

Thanks for your answer. I run RegScanner, looking for "\\" in HKRC,
but I found no entries pointing to a file/application in the other
network
computer. Besides, if the network computer is running, application
launching time is even much longer. Only deactivating the LAN
connection helps.
Here a small section of a RegScanner result (scanning for
"shell\open").
Entries for other apps are of the same pattern.
...

My applications are installed in C:\Programme\, and the registry
entries seem correct to me.
I don't understand why the explorer seems to look for the associated
application in another place, The launching problem occcurs on
doubleclicking any file, not
just with a specific application.

Thanks for your help.


Hi Stefan,

Use this as example:

Right-click is extremely slow only when Network is enabled:

Explorer Problem, very slow to launch applications if LAN connection
is active

Windows Explorer, on doubleclick on any file, takes about 7 seconds
to
launch the associated application, then another 2 seconds to open
the
file.

I've checked in task manager, no apps are draining the CPU
ressources
when exlorer hangs on the launch. All apps are responding that way.
Opening the context menue with a right-click on a file needs 7
seconds too.

If I start let's say, Word or Excel, the apps load right away.
Then I go in File/Open and open a file. The file opens immediately.

The setup:

P4 - 3GHz, 1 GB RAM
WinXP Pro SP2
PCI Ethernet adapter linked to Internet / LAN by a Zyxel 650HW
(ADSL-Router/Switch).

There is a network activity in the app-launching time: LAN
Connection status shows
Activity. 12 packets sent.
If the other network computer is running, time to launch an
application is 75 seconds.
It doesn't matter if the Internet Firewall / Symantec Personal
Firewall are activated or not.

However, deactivating the LAN connection results in an immediate
launching the apps.

SysInternals FileMonitor shows QUERY INFORMATION for every
application installed on my system.
Here a very small section as an example, during launching Winamp.exe
by doubleclicking an *.ogg file:
...

Are there any suggestions what to do?
