20 things you dont know about Windos XP

You’ve read the reviews and digested the key feature enhancements and operational
changes. Now it’s time to delve a bit deeper and uncover some of Windows XP’s secrets.
1. It boasts how long it can stay up. Whereas previous versions of Windows were coy
about how long they went between boots, XP is positively proud of its stamina. Go to the
Command Prompt in the Accessories menu from the All Programs start button option,
and then type ‘systeminfo’. The computer will produce a lot of useful info, including the
uptime. If you want to keep these, type ‘systeminfo > info.txt’. This creates a file called
info.txt you can look at later with Notepad. (Professional Edition only).
2. You can delete files immediately, without having them move to the Recycle Bin first.
Go to the Start menu, select Run… and type ‘gpedit.msc’; then select User Configuration,
Administrative Templates, Windows Components, Windows Explorer and find the Do
not move deleted files to the Recycle Bin setting. Set it. Poking around in gpedit will
reveal a great many interface and system options, but take care — some may stop your
computer behaving as you wish. (Professional Edition only).
3. You can lock your XP workstation with two clicks of the mouse. Create a new shortcut
on your desktop using a right mouse click, and enter ‘rundll32.exe
user32.dll,LockWorkStation’ in the location field. Give the shortcut a name you like.
That’s it — just double click on it and your computer will be locked. And if that’s not easy
enough, Windows key + L will do the same.
4. XP hides some system software you might want to remove, such as Windows
Messenger, but you can tickle it and make it disgorge everything. Using Notepad or Edit,
edit the text file /windows/inf/sysoc.inf, search for the word ‘hide’ and remove it. You can
then go to the Add or Remove Programs in the Control Panel, select Add/Remove
Windows Components and there will be your prey, exposed and vulnerable.
5. For those skilled in the art of DOS batch files, XP has a number of interesting new
commands. These include ‘eventcreate’ and ‘eventtriggers’ for creating and watching
system events, ‘typeperf’ for monitoring performance of various subsystems, and
‘schtasks’ for handling scheduled tasks. As usual, typing the command name followed by
/? will give a list of options — they’re all far too baroque to go into here.
6. XP has IP version 6 support — the next generation of IP. Unfortunately this is more
than your ISP has, so you can only experiment with this on your LAN. Type ‘ipv6 install’
into Run… (it’s OK, it won’t ruin your existing network setup) and then ‘ipv6 /?’ at the
command line to find out more. If you don’t know what IPv6 is, don’t worry and don’t
bother.
7. You can at last get rid of tasks on the computer from the command line by using
‘taskkill /pid’ and the task number, or just ‘tskill’ and the process number. Find that out by
typing ‘tasklist’, which will also tell you a lot about what’s going on in your system.
8. XP will treat Zip files like folders, which is nice if you’ve got a fast machine. On
slower machines, you can make XP leave zip files well alone by typing ‘regsvr32 /u
zipfldr.dll’ at the command line. If you change your mind later, you can put things back
as they were by typing ‘regsvr32 zipfldr.dll’.
9. XP has ClearType — Microsoft’s anti-aliasing font display technology — but doesn’t
have it enabled by default. It’s well worth trying, especially if you were there for DOS
and all those years of staring at a screen have given you the eyes of an astigmatic bat. To
enable ClearType, right click on the desktop, select Properties, Appearance, Effects,
select ClearType from the second drop-down menu and enable the selection. Expect best
results on laptop displays. If you want to use ClearType on the Welcome login screen as
well, set the registry entry HKEY_USERS/.DEFAULT/Control
Panel/Desktop/FontSmoothingType to 2.
10. You can use Remote Assistance to help a friend who’s using network address
translation (NAT) on a home network, but not automatically. Get your pal to email you a
Remote Assistance invitation and edit the file. Under the RCTICKET attribute will be a
NAT IP address, like 192.168.1.10. Replace this with your chum’s real IP address — they
can find this out by going to www.whatismyip.com — and get them to make sure that
they’ve got port 3389 open on their firewall and forwarded to the errant computer.
11. You can run a program as a different user without logging out and back in again.
Right click the icon, select Run As… and enter the user name and password you want to
use. This only applies for that run. The trick is particularly useful if you need to have
administrative permissions to install a program, which many require. Note that you can
have some fun by running programs multiple times on the same system as different users,
but this can have unforeseen effects.
12. Windows XP can be very insistent about you checking for auto updates, registering a
Passport, using Windows Messenger and so on. After a while, the nagging goes away, but
if you feel you might slip the bonds of sanity before that point, run Regedit, go to
HKEY_CURRENT_USER/Software/Microsoft/Windows/Current
Version/Explorer/Advanced and create a DWORD value called EnableBalloonTips with
a value of 0.
13. You can start up without needing to enter a user name or password. Select Run…
from the start menu and type ‘control userpasswords2’, which will open the user accounts
application. On the Users tab, clear the box for Users Must Enter A User Name And
Password To Use This Computer, and click on OK. An Automatically Log On dialog box
will appear; enter the user name and password for the account you want to use.
14. Internet Explorer 6 will automatically delete temporary files, but only if you tell it to.
Start the browser, select Tools / Internet Options… and Advanced, go down to the
Security area and check the box to Empty Temporary Internet Files folder when browser
is closed.
15. XP comes with a free Network Activity Light, just in case you can’t see the LEDs
twinkle on your network card. Right click on My Network Places on the desktop, then
select Properties. Right click on the description for your LAN or dial-up connection,
select Properties, then check the Show icon in notification area when connected box.
You’ll now see a tiny network icon on the right of your task bar that glimmers nicely
during network traffic.
16. The Start Menu can be leisurely when it decides to appear, but you can speed things
along by changing the registry entry HKEY_CURRENT_USER/Control
Panel/Desktop/MenuShowDelay from the default 400 to something a little snappier. Like
0.
17. You can rename loads of files at once in Windows Explorer. Highlight a set of files in
a window, then right click on one and rename it. All the other files will be renamed to
that name, with individual numbers in brackets to distinguish them. Also, in a folder you
can arrange icons in alphabetised groups by View, Arrange Icon By… Show In Groups.
18. Windows Media Player will display the cover art for albums as it plays the tracks — if
it found the picture on the Internet when you copied the tracks from the CD. If it didn’t,
or if you have lots of pre-WMP music files, you can put your own copy of the cover art in
the same directory as the tracks. Just call it folder.jpg and Windows Media Player will
pick it up and display it.
19. Windows key + Break brings up the System Properties dialogue box; Windows key +
D brings up the desktop; Windows key + Tab moves through the taskbar buttons.

To prolong for restarting after windows update

Open Registry, Navigate to "HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\windows\Windowsupdate\AU". If both the sub-keys "Windowsupdate\AU" are not present, create tjese with "Edit->new->key". Create a new entry "RebootWarningTimeoutEnabled" in the right side of the Registry editor by clicking on "Edit->new->DWORD-Value". Open it and set its value to 1. With this you enable the instruction of an interval. Create another value called "RebootWarning-Timeout". Enter the desired span in minutes as the value eg. 30. Additionally, the span between the consistent "Restart later" messages can also be prolonged. This can be done with other entries in the Registry key used above. Create a DWORD-Value with the name "Reboot-RelaunchTimeoutEnabled" and set it to 1. Then create the DWORD value, "RebpptRelaunch-Timeout" and enter the desired duration in minutes after which Windows should repeat the message.

Restrict User Timely login

Xp offers a possibility of deciding the logon times for each user in the system.Comfortable access to the settings is howev er only possible with the server version. The quickest way to do this in XP is by command line.
The "net user" command followed by the appropriate user account and the option "/times" enabhle the configuration of the logon times. For example to restrict access to the guest account, enter the follwing command
net user guest /times:Mo Fr,10 18;Sa,9 12
The change is effective immediately. The user can login from Monday to Friday between 10 to 18 and Saturday between 9 to 12. Outside this range will ask for password. And even if you give correct password, it will reject it being wrong.
To cancel the timely constraing just type
net user guest /times:all

Allow usrs to access system services

You can curtail the services used on the network. Such tasks are regulated by group policies. On a local system, in your case, you are however required to define security template. This way you can apply the desired settings on the machine via the Snap-in "Security Configuration and analysis".
First load the Microsoft Management Console. Click on Start->Run, type "mmc" and click on "OK". Open the existing console file or create a new one by clicking on "File->Add/Remove Snap-in". Then in the Standalone tab click on "Add". Now close all the dialog boxes that have been opened. In the console, now open the "Security template" by clicking on the preceding plus sign. Right click on the desired directory and select "New Template". Name the template, give a description for it and click on "OK". Open the "Security template" folder and the file with the new template that you created. Go to the entry "System Service" under "Compatws". Right click on the desired service for e.g. Print Queue" and select properties. Activate the option "Define this policy setting in the template". The security setting are opened. Here click on "Add" in the input field of the following dialog box, type the name of the user who should get the rights to the service. Click on "Verify name" and on successful colclusion, click ok. The new user is now added to the previous dialog box and is marked. Under this, you can define the authorizations for him. A user should at least able to "Read". "Start, pause and suspend" to be able to start and end a service. Activate the necessary control box in the "Allow" column. Finally, confirm the settings with "Apply" and "OK". Again, defina the start moder or the service in the original dialog box. Select Automatic" to do this, and reconfirm with "Apply" And "OK".

Some Important Tricky Issues

Well, the total thing is going very long, lets do it in short. Open registry and navigate to "HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies\explorer". Under this create a DWORD-Value and name it from the list below to impose restriction. The value of which will be 1 to restrict and 0 to remove restriction. Lets look at the following list:
NoDeletePrinter: Disables Deletion of already installed Printers
NoAddPrinter: Disables Addition of new Printers
NoRun : Disables or hides the Run Command
NoSetFolders: Removes Folders from the Settings option on Start Menu (Control Panel, Printers, Taskbar)
NoSetTaskbar: Removes Taskbar system folder from the Settings option on Start Menu
NoFind: Removes the Find Tool (Start >Find)
NoDrives: Hides and does not display any Drives in My Computer
NoNetHood: Hides or removes the Network Neighborhood icon from the desktop
NoDesktop: Hides all items including, file, folders and system folders from the Desktop
NoClose: Disables Shutdown and prevents the user from normally shutting down Windows.
NoSaveSettings: Means to say, ‘Don’t save settings on exit’
DisableRegistryTools: Disable Registry Editing Tools (If you disable this option, the Windows Registry Editor(regedit.exe) too will not work.). So be very careful.
NoRecentDocsHistory: Removes Recent Document system folder from the Start Menu (IE 4 and above)
NoFileMenu _ Hides the Files Menu in Explorer
NoActiveDesktop – No Active Desktop
NoActiveDesktopChanges- No changes allowed
NoInternetIcon – No Internet Explorer Icon on the Desktop
NoFavoritesMenu – Hides the Favorites menu
NoChangeStartMenu _ Disables changes to the Start Menu
NoFolderOptions _ Hides the Folder Options in the Explorer
NoLogoff – Hides the Log Off …. in the Start Menu
NoViewOnDrive – Restrict a drive to open
NoTrayContextMenu – No context menu in tray.
NoStartMenuSubFolders
NoWindowsUpdate
NoViewContextMenu
EnforceShellExtensionSecurity
LinkResolveIgnoreLinkInfo
NoDriveTypeAutoRun
NoStartBanner
NoSetActiveDesktop
NoNetConnectDisconnect
ClearRecentDocsOnExit: Clears the Recent Documents system folder on Exit.
RestrictRun – Disables all exe programs except those listed in the RestrictRun subkey
Under the same key "HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies" you can create new subkeys other than the already existing Explorer key. Now create a new key and name it System. Under this new key, system we can create the following new DWORD values(1 for enabling the particular option and 0 for disabling the particular
option):
· NODispCPL: Hides Control Panel
· NoDispBackgroundPage: Hides Background page.
· NoDispScrsavPage: Hides Screen Saver Page
· NoDispAppearancePage: Hides Appearance Page
· NoDispSettingsPage: Hides Settings Page
· NoSecCPL: Disables Password Control Panel

· NoProfilePage: Hides User Profiles Page
· NoDevMgrPage: Hides Device Manager Page
· NoConfigPage: Hides Hardware Profiles Page
· NoFileSysPage: Hides File System Button
· NoVirtMemPage: Hides Virtual Memory Button
Similarly, if we create a new subkey named WinOldApp, we can add the following
DWORD values under it(1 for enabling the particular option and 0 for disabling the
particular option):
Disabled: Disable MS-DOS Prompt
NoRealMode: Disable Single-Mode MS-DOS.
