change start up and shutdown of your win xp


Have you ever felt bugged-up with the Start-up and Shutdown jingle of your Windows XP or Vista ? If yes, here is the solution, now you use any of your favorite voice or music or dialogue as your PC’s shutdown and start up.It’s a simple 4 step process. Step 1. Choose the track which you want to play at start-up and shutdown jingles,Limitations are* It should be in .WAV format.* The size of file should not be large, prefer keeping them within in 1 Mb, otherwise your startup will take a bit longer.If the file you want to make your start-up or shutdown is not in .WAV format, you can easily convert them using any converter. Step 2. Now rename these files as “Windows XP Startup.WAV” and “Windows XP Shutdown.WAV” respectively. Step 3.Now Go to “C:\WINDOWS\MEDIA”, here you will find files “Windows XP Startup.WAV” and “Windows XP Shutdown.WAV”, move them to some other locations, this step is required for, in case you need to revert back these sounds, else you can ignore this step. Step 4. Now the files you have chosen and renamed, just copy-paste or cut paste them in “C:\WINDOWS\MEDIA”, here you go, now you can enjoy the new Start-up and shutdown.


restricted pc shutdown


Both Vista and Windows XP let you take control of preventing a user not to shutdown the machine by editing the group policy. For example if your friend is using your computer and you went somewhere ( and you have still some unsaved document left) and he shutdowns the pc without saving them…you loose a good amount of data. ( Trust me I have lost one whole blog post and project code at same time ). This is what you can doRestrict PC Shutdown* Type gpedit.msc in run dialog box [ WIN KEY + R ]* This will open Group Policy Editor. Now there are two things in it, Computer Configuration and User Configuration* Click on User Configuration > Administrative Templates > Start Menu and Task Bar* Now look for “remove and prevent access to shutdown command”* Double Click and Enable it.* Exit the group policy editor.This setting removes the Shut Down option from the Start menu and disables the Shut Down button on the Windows Security dialog box, which appears when you press CTRL+ALT+DEL. This setting prevents users from using the Windows user interface to shut down the system.Now if you try to shutdown by clicking on start , the shutdown button must have disappeared. Moreover check the task manager and you will find all shutdown,restart and others disabled except switch user.


screenshotscreen.....
Screen Shot….Hold down the control key and look in the upper right side above your letter keys for “Print Screen SysRq” or “Prnt Scrn” or something to that effect and hit it.Next, open a new file in “Paint” (Probably Start/Programs/Accessories/Paint).Next under Edit, select Paste.Next, under File, select “save as” give it a name, and be to sure choose JPEG where it says Save as Type.You can now make screenshots of whatever you wish. This is cool.To get the large size of Screen press F11 & then repeat above procedure again……
safe mode in boot list

Safe mode is required when you have to fix a problem such as virus infection or uninstalling drivers in your windows XP. generally we need to use F8 Key to get into safe mode and if not timed properly you will need to restart windows xp again. Here is a small trick which lets you add Safe mode by default into your Boot list. You will see it when you restart your windows xp machine.Steps to Add Safe Mode in Boot list* Go to control panel > System.* Click on Advanced Tab.* Then click on settings under the startup and recovery action.* Click on edit under system startup to indirectly edit your boot.ini file.* Add the following entry “multi(0)disk(0)rdisk(0)partition(2)\WINDOWS=”XP - Safe Mode” /fastdetect /safeboot:minimal /sos /bootlog” without quotes .Add safe mode to your boot listThats it, restart your machine and you will see another label as “XP- Safe Mode” added to the list.PS: This option is also used for adding any other windows installation on other partition. 


some tricks

This is a complimation of computer tricks, mainly security and privacy related.

Getting Ip’s:–

To see the ip all computers you are connected to (web servers, people attempting to **** into your computer).Go to dos (start>run>type command) and run the netstat command. Type netstat /? for details.

Type netstat -r at the command prompt to see the ip of all computers you are connected to

In MSN (and other programs) when you are chatting to someone everything you type goes through the MSN servers first (they act as a proxy) so you see their ip rather than who you are chatting to. You can get round this by sending them a file as MSN doesn’t send file through its proxy.When you type the netstat -r (or -a for a different view) the ip’s are under the foreign address table. The ports are seperated by a : . Different programs use different ports, so you can work out which ip’s are from which program.

Connecting to other computers and what ports are:–

Servers send information. Clients retrieve. Simple.Windows comes with a built in program to connect to other computers called telnet.To start Windows telnet Start menu> Run> type Telnet. Click connect> remote systemPorts are doors into computers. Hosts are computer names(ip number or a name that is translated into the ip automatically)Different programs open different ports, but they always open the same ports so other computers know which port to connect to. You can get a port list listing all the different ports, but a basic one is:11 :- Sends info on the computer21 :- FTP (File transfer program)23 :- Telnet (Login to the computers command line)25 :- Smtp (Sends mail)80 :- Http (Web pages
)There are thousands of different programs using different ports. You can get programs called portscanners which check a computer for all ports up to a certain number, looking for ways in. You can portscan a computer looking for ways-in.Anyway, back to telnet.Type www.yahoo.com as the host and port as 80 the click connect.If nothing happens, you’re in. Wow. You are connected to Yahoo’s server.You can now type http commands (you are connected to an http server, so it supports http commands). Ie. on an ftp server you can type open and it will do something. On an http server it will just wonder what the hell you are on about.Type get / http/1.0 then press enter twice to get the file on the server at / (try /index.html) etc.)

Making undeletable, unreadable folders

Tested on Windows 95/98By holding down alt, then typing numbers on the number pad (right of the keyboard) you can create special characters. If you hold down alt, then press 1, then let go, you got the ascii character 1. You try some randomn numbers. This goes all the way up to 255. Open a dos prompt, and type md (alt+1+9+4)someword. md is the dos command to make a directoy, now try and open the directory in Windows, you can’t. To open it, type ren (alt+1+9+4)someword someword (ren is the dos command to rename)

Proxies

Proxies are computers that you connect through, hiding your computer. Most aren’t anonymous, they give away your ip. Some are. Good anonymous proxies: mail.uraltelecom.ru:8080 and 194.247.87.4:8080.Different programs require different ways of using proxies. To do it in internet explorer 5 go to tools, internet options, connections, settings. In the above proxies they are in the format host:port

Password files

If you lock yourself out of Windows stuff, all passwords are stored in files called *.pwl in C:windows.In Unix, passwords are normally stored at etc/passwd. This can be viewed using the cat command (prints a file to screen): cat etc/passwd. Make sure you’re passwords are shadowed (not actually in etc/passwd). Also make sure they aren’t in a file called shadow, especically not in a file called etc/shadow.Unix passwords are encrypted far better than Windows one’s (to be fair, Windows 95 isn’t designed for users), but can still be cracked through a program called jon.
