Things that slow your PC down

You are install one CCTV Software in your Customer PC. During boot up a computer brand new from the store, and to revel in the galactic super-speed in which it loads. It’s another to keep it running at that same speed, especially after some months have passed.

There are many reasons why your computer isn’t running at its optimum. Fortunately, they’re all very easy to solve. Read on to find out what slows your PC down, and what you can do about it.

An overloaded startup
Most applications you install usually add themselves automatically to your Start Up folder. This results in a slower startup because of the time needed to load them all. If your computer used to boot at the speed of light, but now moves slower than an old lady at the zebra crossing, this might be your problem.

SOLVE THIS: by accessing the MSCONFIG command through your search bar or run application, heading to the Startup tab at the top, and unchecking all unnecessary programmes. Seriously, do you really need iTunes to boot whenever you start your computer?

Too many temporary files
Whenever you look at webpages, watch videos, look at photos or even type on Microsoft Word, your computer stores temporary files so that it can load up faster the next time round. These files build up over time and may slow your computer down, especially since they’re usually located in your OS drive.

SOLVE THIS: By running Windows Disk Cleanup, found in Accessories, regularly.

A fragmented disk
A very old school problem, but still a very real one. Disk fragmentation occurs when the file system can’t or won’t allocate enough continuous space to store a complete file. This results in gaps within that file, and can make that file run slower than it usually would. Sometimes, those gaps occur when the OS deletes a file it doesn’t need any more. (This is safe though, your OS is smarter than you think).

SOLVE THIS: By running the Disk Defragmenter, also found in Accessories, regularly. We suggest not using the computer whilst the Defragmenter runs so as to minimise more fragmentation 

Programs uninstalled improperly
What a mouthful this header is. A PC does not work like a MAC – simply deleting the application you don’t want won’t cut it, and leaves behind remaining files that may cause your computer to slow down.

SOLVE THIS: By always uninstalling programs with the proper uninstall.exe, or remove them via the Control Panel. Go one step further to delete leftover files from the folder manually after uninstallation. This could include save games, 3rd party add ons, screenshots and etc.

A full OS disk
Many people make the mistake of saving everything possible into their C:/ drive, and that usually hosts their OS, or operating system. Once that drive gets too full, it slows down, thereby slowing down your entire computer’s processing speed.

SOLVE THIS: by partitioning your drive into C:/ and D:/ and saving your data in D:/. The lack of strain on your OS drive will let it run faster. You might be pleasantly amazed at the difference this can make.

Background anti-viruses
Anti-viruses are always helpful, but can sometimes do more harm than good. Since they’re always running and usually boot together with your computer, they can slow down processes considerably. Strangely enough, it’s always the ones you’ve got to pay for that wreak the most havoc.

SOLVE THIS: By disabling auto scans and updates, or by switching to a more lightweight, freeware anti-virus. Some have suggested Avira and AVG Antivirus, but it’s your job to ask your trusted geek friend what he’s using.

Spyware and viruses
Malicious software often heads straight for your Windows Registry or core file system, slowing down your computer. They can sneak in with applications you download online and install, and can also hop in from less-than-savoury websites you visit.

SOLVE THIS: While spyware and viruses can be removed manually by deleting them from your registry, some can be more persistent. In this case, use an automatic spyware remover – tons are available if you do a Google search. One of the more popular one is Ad-Aware Spyware Remover.

How to Reset / Recover / Change Forgotten Administrator Password in Windows?

Many times we face this problem when we or our friends forget Administrator account password in Windows and can't log into Windows. So here we are posting a few methods which can be used to change, reset or recover forgotten Windows password in Windows.

DISCLAIMER: Following information should be used only if its your system and you have forgotten account password. Don't use this information to access a system which is not yours without permission.

Method 1: Using Welcome or Login Screen

This method is the first thing which should always do whenever you forget your Windows login password. When we install Windows, it automatically creates a hidden user account"Administrator" and sets its password to blank. So if you forget your user account password then try this:

1. Start your computer and when you see Windows Welcome screen (Login screen), press <ctrl>+<alt>+<del> keys twice and it'll show Classic Login box.

2. Now type Administrator in Username box and leave Password box empty. Now press Enter and you should be able to log into Windows.

3. Now you can reset your account password from "Control Panel -> User Accounts".

Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

Method 2: Using Password Reset Disk

Windows XP and later Windows versions provide a built-in method to recover forgotten password by using "Password Reset Disk". If you created a Password Reset Disk in past, you can use that disk to reset the password.

If you don't know how to create a password reset disk, lets tell you in details. You can create the password reset disk using Control panel -> User Accounts applet.

First open Control Panel and click on User Accounts icon. It'll open User Accounts window. Now click on your user account and then click on "Prevent a forgotten password" link given in left-side pane. It'll open forgotten password wizard as shown in following screenshot:

Follow the instructions and you'll have a password reset disk in your hand.

Method 3: Using "Net User" DOS Command

You can also use a built-in DOS command "Net User" to change any desired user account password within seconds. You'll need access to Command Prompt window in this method:

1. Open Command Prompt as Administrator as mentioned here and run following command:

net user

2. It'll list all available user accounts in Windows.

3. Now run following command:

net user user_name new_password

Replace "user_name" with the desired user account name and replace "new_password" with your desired password.

For example:

net user "Arindam Bhadra" 12345

Here "Arindam Bhadra" is the user account name and 12345 is the new password.

4. That's it. It'll immediately change the user account password.

Method 4: Using Windows XP Setup Loophole

If the above mentioned tricks don't work for you, try following trick which is actually a loophole in Windows XP Setup and also a big security hole:

1. Boot using Windows XP Setup CD and follow the instruction like Accepting EULA, etc.

2. When it asks to repair your existing Windows installation, accept it and press "R" key to run the repair.

3. Setup will start repairing your Windows and will start copying files, etc.

4. After a few minutes setup will restart your system and when it restarts, don't press any key when it shows "Press any key to continue...". Otherwise Setup will start from the beginning. Don't press any key and setup will resume where it left.

5. Now it'll start doing other tasks and will show a small progressbar with a few details in left side.

6. Look carefully at the details and when it shows "Installing devices", press <Shift>+F10 keys together in your keyboard.

7. It'll open a Command Prompt window. Now type nusrmgr.cpl and press <Enter> key.

8. It'll open the same "User Accounts" window which you see in Control Panel.

9. Now you can remove or reset any account password without any problem.

Method 5: Using Bootable Rescue Disk

You can also use various bootable rescue CDs to reset your Windows password as mentioned in following link:

Method 6: Perform a Clean Installation of Windows

If all fails, simply reinstall Windows and create new user account. To recover lost data, you can use Data recovery tools available on net but the chances will be less to get your data back.

That's all we can suggest. If you know about any other method or tool, feel free to share it in your comment.....
