When you forget your password

When you forget your password:

If you are using a laptop/pc you can use many different type of passwords to secure your data (we are not talking about your data on a server/network, talking about your local data on your laptop/pc’s hard disk).

Windows passwords:
You can make an account and put safety by activating a password for your account(Control Panel /User Accounts gives you enough options do it) but remember if you make more than one accounts, the other user(s) by default will have access to the others’ data but you can change the privacy settings if your hard disk is formatted in NTFS.

  • If you forget your password there are some ways to find access to your data (e.g. using different account that has privilege or connecting your hard disk to a different pc/laptop – perhaps you need to change the ownership of folders/files using administrator account to find full access or set a new privilege).

Bios Passwords:
Depends on the type of your pc, usually there are different types of “On Boot Password” available in Bios setup configuration , in this case as soon as you power on your machine it prompts for a password.

*If you forget your password, usually there are some ways to clear the bios settings (e.g. removing RTC battery for a while, or changing a jumper , or using a loop back connection to the parallel port in some models) .

Hard disk password:
This is the most secure (and most risky type of password if you forget it), in this case , you will have option to put and enable a Hard Disk Password through the bios settings (or some applications) , the information of this password wont go on your Bios /System Board (goes to the hard disk itself) , so if you forget the password you can not clear it through Bios settings.
In this case again as soon as you power on your machine it prompts for a password.

  • If you forget this password, search on internet specifying the right model of your hard disk and if you are lucky you will find something (see link for example) and if you are not lucky, but your data are so important you can call manufacturer (of your hard disk) to find your chance that will be expensive I guess.

Differences between XP PRO and XP HOME

Differences between XP PRO and XP HOME ( David Chernicoff)

1-XP Pro systems can join a domain; XP Home systems can't, which limits its use to home and SOHO environments because it can't use any corporate-specific features such as IntelliMirror.

2-Microsoft Internet Information Services (IIS) 5.1 and Personal Web Server (PWS) are found only in XP Pro.

3-Direct access to the Administrator account is available only in XP Pro. XP Home users must log on using Safe mode to access the Administrator account.

4-XP Pro supports Remote Desktop, which is basically a single-user version of Windows 2000 Server Terminal Services. XP Home supports only Remote Assistance.

5-Networking-related Group Policy Objects (GPO) are available only in XP Pro. XP Home supports no group policies.

6-Microsoft Remote Installation Services (RIS) and Sysprep are supported only in XP Pro.

7-The Network Monitor application is available only in XP Pro.

8-The UI for IP Security (IPSec) is available only in XP Pro.

9-SNMP support, Simple TCP/IP Services, the service access point (SAP) and Client Services for NetWare (CSNW) are available only in XP Pro.

10-XP Home supports only simple file sharing. Detailed file-level security permissions such as those found in Win2K are available only in XP Pro, which also supports the simple file-sharing model that XP Home uses.

11-XP Pro lets users limit the number of connections to shared folders and control user access by account. XP Home users access shared folders through the Guest account, which is disabled by default in XP Pro.

12- You can upgrade Windows NT 4.0 Workstation and Win2K Professional only to XP Pro. You can upgrade Windows 9x versions since Windows 98 only to XP Home. Neither version supports upgrades from Windows 95.

Watch what you buy :FlexPlay DVD (School girlfriend/wife)

Watch what you buy :FlexPlay DVD

It’s a new type DVD that automatically blanks itself after a certain period of time. It could be quite useful perhaps for DVD- Video shops to give people a way to rent DVDs without applying for membership cards ,or copy restriction. A funny friend says FlexPlays are like school girlfriends while DVDs are like a wife!
But if you want to buy something for xmass and give it to a friend or family , make sure they wont watch it twice!.

If your windows 98 (or me or 95) fails to boot

Using an old operating system is not always bad, and sometimes its much easier to get it fixed . So if your windows 98–95-me wont boot (because of a software damage like virus , deleting files , corrupted files and so on) try to follow this recipe:

1-Boot from win98 (or 95 or me ) CD (maybe you need to change boot priority in bios) and choose “Start windows with CD-Rom support”
2- Change drive to C: and change directory to C:\windows
3- Rename win.com to something else like : C:\WINDOWS> Ren win.com win.old
4- Change drive to D: (your Cd-rom drive name) and change directory to D:|\Win98
(or D:\Win95 for Win95 or D:\win9x for WinMe)
5-Run Setup.exe
6- If your hard disk is not damaged , it will check the partitions and offers you a new folder to install Windows (like: windows.000) , change “Windows.000” to “Windows” and click on “next”
(if you don’t change it to “Windows” you wont lose your data but you will lose your applications and drivers.
7-Follow Setup program to the end .
Your windows is ready ! try to remove extra applications and install a good anti virus.

How to clone a hard disk

You have a hard disk and you would like to clone it ( identical )on a new hard disk (for instance the size of the first hdd is not enough and you would like to have everything the same but on a bigger hdd , or you just want to backup everything including your windows and so on ) , what you need to do:

Maybe you think “so easy just install the second hdd as slave , then format it and then start some copy and pasts” , or maybe you prefer to use an image software.

Copy and paste will copy your data files and folders but can not make the second hdd bootable and windows wont start.

The image software also needs lots of space , but there is a different and easy way :

1-Install the second hdd as slave
2-Format it
3-Close all open programs , including anti viruses
4-Go to command mode (using “cmd” or “command “)
And run :
“ Xcopy C:\ X:\ /s /e /c /r /k /h /q “

(C: source , X: destination)
and wait for Dos prompt , ignore sharing error messages

now you can remove the first hdd , change the clone one to master and start your windows as nothing has happened.

p.s: adding /v can verify your copied files , but takes more time.
