Windows Speed-up, Networking Improvements and Optimisation

Want to know how to speed up Windows by knowing which services to disable? Increase the performance of your network by adjusting the connections made by TCP/IP... then read on!

Is anything missing? Do you have any information to share? What do you think about this section? Please contact Guru Guy and let him know!

Note: When these sections instruct you to "run", "type" or execute command lines, they mean typing the commands/instruction into Start->Run. Any reference to HKLM (HKey Local Machine) is a location within the Windows Registry (Start->Regedit). These tips & tricks assume you have sufficient knowledge to carry out the instructions and Guru Guy is not responsible for any consequences of implementing them.

Windows Speed-up, Networking Improvements and Optimisation
To modify Windows Start-Up services, auto-start programs and boot menu, click start, run and type:
msconfig
Secure Windows and speed it up by disabling unnecessary services (less running the less to exploit and less memory required).
Unnecessary services (check consequences before doing such):
Alerter, Application Management, ClipBook, Distributed Link Tracking Client, Distributed Transaction Coordinator, Error Reporting, Help & Support, Indexing Service, Machine Debug Manager, Messenger, Microsoft Software Shadow Copy Provider, NetMeeting Remote Desktop Sharing, Network DDE, Network DDE DSDM, Performance Logs and Alerts, Portable Media Serial Number, Protected Storage, QoS RSVP, Remote Desktop Help Session Manager, Routing and Remote Access, Remote Registry, Secondary Logon, Server, Smart Card, Smart Card Helper, SSDP Discovery, System Event Notification, System Restore, Task Scheduler, Telephony, Telnet, Terminal Services, UPS, Windows Zero Config, Universal Plug and Play.
For a more thorough list of what services can be disabled and their consequences of doing such, Tech Republic have a fantastic full-fledged PDF here.
Improve Network Speeds:
HKEY_LOCAL_MACHINE->SYSTEM->CURRENT CONTROLSET -> SERVICES -> TCPIP -> PARAMETERS
TCP Window value set as DWORD representing bytes.
FOR BROADBAND SET: GlobalMaxTCPWindowSize=256960
ALSO NEED LARGE WINDOW SUPPORT: Tcp1323Opts=1
LAN SPEED:
(a) EnablePMTUDiscovery=1
(b) EnablePMTUBHDetect=0
(c) SackOpts=1
(d) TcpMaxDupAcks=2
Put Core XP files in RAM (use when you have more than 512MB RAM):
HKEY_LOCAL_MACHINE->SYSTEM->CurrentControlSet->Control Session Manager->
Memory Management->DisablePagingExecutive=1
Remove browsing for scheduled tasks in Windows 2000:
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Explorer/
RemoteComputer/NameSpace
Under that branch, select the key:
{D6277990-4C6A-11CF-8D87-00AA0060F5BF} - and delete it.
Stuck Applications timeout can be made shorter:
Hkey_Current_User\Control Panel\Desktop
AutoEndasks icon and change 'value data' to 1.
HungAppTimeout icon and change 'value data' field to reflect time (in milliseconds).
Also Services can hang:
Hkey_Local_Machine\System\CurrentControlSet\Control
WaitToKillService icon and change 'value data' to time.
Use "Netstat" in the command line to see all TCP/IP Networking connections:
Netstat -b (show program file names calling TCP Connections)
-a (show all connections)
-n (show numeric ports instead of 'friendly names' e.g. 25 instead of SMTP
e.g. Netstat -b -a -n
Speed-up Windows for "Gaming Mode" to make sure the computer is as responsive as possible, by processing all pending tasks so they don't start later
Start->Run
Rundll32.exe advapi32.dll,ProcessIdleTasks
In Windows XP, when accessing directories with hundreds/thousands of files, the LastAccessStamp slows things down. To turn it off (prevents the stamp on all files being marked when they were last accessed) do the following:
a. Regedit: HKLM\System\CurrentControlSet\Control
b. Right-click on he subkey "FileSystem" -> NEW->Dword
c. Label it NtfsDisableLastAccessUpdate
d. Allocate it a value of 1
e. Restart Windows.
Evalue what network shares exist on your computer.
Command: "net share" in CMD will reveal a list.
To delete a share, type: 'net share [sharename]/DELETE'
Analyse security of any Windows XP computer (SP2) by loading Security Configuration Tool:
a. Start->Run->MMC
b. Add/Remove snapin from the Console1 menu. Add->Security Configuration & Analysis
c. Create a database of your current settings: Right-Click on Security Configuration & Analysis->Open Database
d. Type name of database "my security settings" and press ENTER
e. Import template->Anyone as follows: default = setup security.ini, to highest at hisecws.inf
f. Save this MMC Console to avoid having to re-do all of the above: Console->Save As->type "Security Analyser"
g. Right-Click on Security and Anaylsis and choose "Analyse Computer Now".
h. Pane on left shows branches with results.
Sometimes Windows XP TCP/IP Stack needs repairing (if third-party firewalls muck it up) do:
a. start->run->CMD
b. netsh winsock reset catalog
