Try this :
1- Icon cache may be corrupted : delete it and Windows will recreate it at new boot :
Local Setting and IconCache.db are hidden : set the explorer to see hidden
files in File Options | Display tab | show hidden folder and files...
and delete IconCache.db:
C:\Documents and Settings\"User Name"\Local Settings\Application Data\IconCache.db
2- Set the maximum cached icons(default is 500)
HKLM\SOFTWARE\Microsoft\Windows\Current Version\Explorer
Max Cached Icons
Reg_SZ
value can be set from 100 to 4096
Try with 2000
If this key do not exist created it.
3- Set explorer to use à different process (multi-threads):
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
Create this key:
DesktopProcess
Reg_DWord
value 1
4- Change the Windows priority separation :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl
Create this key :
Win32PrioritySeparation
Reg_DWord
Value 26 in HEX
5- Number of memorized folders setup : default is 400.
Set it to 2000
Remark : Tweak UI 2.10 for W xp and W 2003 have this option but there is a
bug in the file names of the values.They do nothings ... ;-)
Use this .reg to fix the problem :
---------------------------------------------------------- cut here----------------------------------------------------
Windows Registry Editor Version 5.00
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\BagMRU]
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\Bags]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell]
"BagMRU Size"=dword:000007D0
[HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam]
"BagMRU Size"=dword:000007D0
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoSaveSettings"=dword:00000000
-------------------------------------------------------- cut here----------------------------------------------------------
Also:
A good maintenance of W xp is required from time to time.
Here some hints:
1- Use chkdsk to check the integrity of your hard disk:
Windows explorer | right click on disk icon |
properties | tab "tools" | "check errors" | check both options
ok and restart your computer
or
Start | Run | cmd | chkdsk X: /F /R /V ,
Where X= disk volume
For the results un applications log:
Souce : Winlogon
ID : 1001
2) Clean the temporary files:
Start | Run | cleanmgr.exe
3) Defrag the volumes of the HD :
Start | Run | Defrag.msc
For multiple volume defrag use this:
http://www.dougknox.com/utility/scripts_desc/defrag_all.htm
4) Check devices and drivers and upgrade them if needed
Start | Run | devmgmt.msc
a)
Devices error codes:
http://support.microsoft.com/Default.aspx?kbid=310123
b)
To find recent drivers
www.driverfiles.net [In Eng.]
or
[in Fr.]
www.eu.microsoft.com/france/telechargements/drivers/default.asp
www.touslesdrivers.com
www.clubic.com/pilotes.html
5) Check the services configuration:
The mandatories services must be started and in automatic mode
The others in manual...or disabled....
More info on W xp services:
http://www.theeldergeek.com/services_guide.htm
6) Check the applications started at boot and keep them
to the minimum.
instead of using msconfig used Starter from CodeStuff...
http://codestuff.mirrorz.com/
Check for applications in your account and All users
(from an admin account...)
7) Control what's running on that PC with those tools:
Autorun
http://www.sysinternals.com/ntw2k/freeware/autoruns.shtml
Process Explorer :
(an enhanced Task Manager!)
http://www.sysinternals.com/ntw2k/freeware/procexp.shtml
8) Defrag the protected files ( Registry , hiberfil.sys, Pagefile.sys etc.)
http://www.sysinternals.com/ntw2k/freeware/pagedefrag.shtml
9) Optimize the prefetching
Run this command :
%windir%\system32\Rundll32.exe advapi32.dll,ProcessIdleTasks
usefull only when the computer is idle...
The service Task Scheduler must be running and in automatic mode.
Check this value:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
The keyEnablePrefetcher REG_DWORD must be set to 3.
10) Safe & Cool ...
Keep your system free of malwares (virus, worms,spywares, etc.)
Keep your PC free of dust and check the temperatures with those tools:
Everest:

SpeedFan

Tell us if those procedures fix the problem.
