Remove UnSigned Driver Installation Warnings

To prevent this warning or to allow new un-signed drivers to be installed do the following:

1. Go to start/run/ then type secpol.msc
2. Browse to local policies/security options
3. Change "Devices: Unsigned driver installation behavior" setting to Silently succeed.
4. Reboot Computer.

Or, especially if you are using Windows XP Home where there is no secpol.msc, right click on your My Computer icon, click properties, change to the Hardware tab, click the "Driver signing" button and click ignore.

Enabling Windows Taskmanger and Registry

Enable Windows Task Manager

First, Open Notepad

then copy below text to notepad,

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000000

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000000
"**del.DisableTaskMgr"=" "

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\]
"DisableTaskMgr"=dword:00000000

then save files as "Taskmanager Enable.reg" not *.txt [without quotes]

and for Restoring the Registry,
do as above,

Windows Registry Editor Version 5.00

Registry and Task Manager can damage from Virus attacks, they will get disabled, by this way you can enable the Registry and task manager.

Remove Softwares of windows and other unwanted Programs

If you want to remove some additional programs that are installed with windows but are not initially visible in Add / Remove, edit a file called "C:\WINDOWS\INF\SYSOC.INF".

In there you will find a listing of programs, and you will note that some programs have the word 'hide' at the end.  Simply remove the word 'hide' but leave the extra comma:

BEFORE:msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7

AFTER:msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7

Now when you open Add-Remove Windows Components, you will see a new choice, in this example, "Windows Messenger"

This Method Can use only in Windows 5 versions.

Protecting Windows XP from Intruders

1. As it was mentioned before, set the Guest and Administrator account passwords. By default, the Guest account password is blank. Make it something difficult, such as a combination of letters and numbers, preferably not based on dictionary words. Control Panel\Administrative Tools\Computer Management\Local Users and Groups\ Highlight User Account, right-click, 'set password'.

2. Remove/Delete any unused accounts, especially any 'remote assistance' accounts.

3. Disable the Guest account since you can't delete it.

4. Rename the Guest and Administrator accounts to unique names. Remove the description of these accounts (in local users and groups). Control Panel\Administrative Tools\Local Security Policy\Local Policies\Security Options Account: Rename Guest Account - Double click and rename the account Account: Rename Administrator Account

5. If you do not need to connect to your computer from a remote machine, be sure to turn off this functionality. Control Panel\Administrative Tools\Local Security Policy\Local Policies\User rights Assessment\ "Access this computer from the network" - remove all users and groups. This should be blank "Deny access to this computer from the network" - this should include all users and groups. Double click on the policy, click Add User or group, click Advanced, click Find Now, highlight all the accounts and click OK.

6. Turn off the Microsoft File sharing in Network Neighborhood if it is not going to be used.

7. Under System Properties\Remote, Turn off Remote Desktop and Remote invitations.

8. Run a software firewall program.

9. Be sure to visit WindowsUpdate to get the latest hotfixes and security patches. There are a lot of them.

Preventing Access in Windows

Prevent Access to Command Prompt

This setting also determines whether batch files (.cmd and .bat) can run on the computer.
If you enable this setting and the user tries to open a command window, the system displays a message explaining that a setting prevents the action.
Note: Do not prevent the computer from running batch files if the computer uses logon, logoff, startup, or shutdown batch file scripts, or for users that use Terminal Services.

START > RUN > GPEDIT.MSC > USER CONFIGURATION > ADMINISTRATIVE TEMPLATES > SYSTEM > FIND PREVENT ACCESS TO THE COMMAND PROMPT > RIGHT CLICK > PROPERTIES > CLICK ENABLE > OK REBOOT

Note: This will disable the command for all users including the local administrator. If you want to disable this for specific users only (and for XP Home users) make the change in the registry. Login to the account you want to change and create the following registry entries:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System\
DisableCMD  dword  0x00000001   to disable command prompt and batch files
or
DisableCMD  dword  0x00000002   to disable command prompt but not batch files

Prevent Access to Registry Editing Tools

If this setting is enabled and the user tries to start a registry editor, a message appears explaining that a setting prevents the action.
To prevent users from using other administrative tools, use the "Run only allowed Windows applications" setting.

START > RUN > GPEDIT.MSC > USER CONFIGURATION > ADMINISTRATIVE TEMPLATES > SYSTEM > FIND PREVENT ACCESS TO REGISTRY EDITING TOOLS > RIGHT CLICK > PROPERTIES > CLICK ENABLE > OK > REBOOT

Prevent XP from using alternate Video Driver

1. Some program or games like Ghost Recon, use alternate Video driver when it can't recognise the Primary Video card driver.
   
   
2. Alternate driver lack AGP support and performance. So this tweak will prevent window XP from using this alternate driver whenever it was called for.
   
   
3. Some bug may appear when using the primary Video driver
   
   
4. Here's how to do it:
5. -Run Regedit.
6. -Go to. --> "HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Control\Video"
7. -There will be 4 'display device GUID' key.
8. -Expand all 4 key.
9. -Open the 'subkey' labelled "000"
10. -Change any 'DWORD' value labelled "MirrorDriver"
11. from '1' to '0'.
12. -Close regedit, restart.
    
    
13. If Graphic card is soo slow (SiS based graphic
14. card) so, if AGP texturing capabilities disabled, my computer will go soo slow.
15. Use a program named "POWERSTRIP" to determine the AGP capabilities (and to overclock my Graphic Card).
