64-bit and 32-bit comparison

The difference between 32 – and 64-bit systems basically boils down to this: The systems can process mowindows 64-bit 7RE and more data RAM. That’s basically it. Both versions of Windows have the same look, it’s just a question of quantity of data that these systems can handle both

64-bit can track more than 4 GB of RAM (maximum 32-bit) treat them, and can handle more parts of the data at once. For the average consumer, is the most important advantage that means better graphics, because 64-bit system more visual details that can handle a machine 32-bit.

1. Speed Optimization

To be able to produce high-speed computer is a significant need in the hardware-spec hardware with high-class also, now that we have limited funds / limited hardware spec can try a few alternatives to improve the performance of our computers, among others, the following manner:

a. defrag Computers regularly

b. do not run services that are not you need

3. To select the Visual Effects should be best for performance, this setting is on the menu controlpanel-> systems-> advanced-> performance.

2.for the Antivirus (freeware) choose a simple anti-virus update  and scheduled for antivirus freeware powerful that I reference like AVG, Avast, Kaspersky. while for local antivirus also not least, this is antivirus / dominant to protect our computers from local virus reference to, among other local antivirus: PCMAV, ANSAV (freeware).

3. Firewalls

Firewall on by default even if the windows are implementing this system, but it’s good you use a software firewall for additional that you connect to the Internet, the firewall security level of your computer more secure, a free application that you can take advantage of the Sygate Personal Firewall.

1. does not update antivirus
update antivirus required for computer users, update antivirus ascertain whether safe to avoid a virus? the answer is not, why? because work as an anti-virus is not same with the handle of a different virus. and powerful antivirus is antivirus that know about how the work virus itself

2. Users of the computer
computer user actually plays an important role in handling the virus, so that the computer not easy to attack by the virus,because the computer user must can monitor all incoming files on the computer, both the image files, applications, music and other files. computer user should understand a file extension this is intended to avoid the attack of the application file which masquerade using an icons but the extension remain. exe (application extension). therefore, the computer user is expected to understand the extension and not only use of available computer facilities.

3. Iterance virus system (loop sistem)
This system is used by a virus to initiate an attack, this system usually used by viruses to make theft of files, file destruction, and the spread of the virus through a USB flashdisk the entry on a computer.
For example:
a computer that has drives C, D, E. fell ill when the computer is a computer virus that attacks the drive C, D, E, F then automatically fell ill (attack) on the computer only drive C, D, E why? because in the computer there are only drive C, D, E. but when plug in a flashdisk in the the machine will be visible to the drive C, D, E, F (F is a USB flash drive) it’s mean a USB Flashdisk also exposed by a virus. because iterance system made by virus to check and run the system continuously (the system did not stop).

The software as it is somewhat irritating that many users have complained, but most of these parameters can be changed to your own taste.
9 useful tweaks in Windows Vista:

1. Disable UAC

In the User Account Control security instructions can be a bit boring. To disable the security on the issue:

* Control Panel > User Account and Family Safety > Turn User Account Control Off or On.

Note: Disabling UAC, reducing the security equipment. If your computer is to inexperienced users, it would be a good idea for the UAC turned on.

2. Start Menu icons do not turn on the power system

You may have noticed that the power icon in the Start menu does not shut down the computer, but sends him to sleep.

Making changes, go to:

* Click Start> Type “CMD” (this opens a command prompt)> type “powercfg.cpl.1″ (and this will open the advanced settings of office)> click on the + next to the “Power Buttons and Lid” field > click on the + next to the “Start Menu and Buttons” field > change the setting from “Sleep” to “Shut Down”.

3. Disable USB Wake

USB devices can sometimes make your computer “wakes up” if you do not want too. This is because the Vista default configuration of the computer power they say that if the USB device is connected to which can be useful, but can be painful. To disable this see:

* Device Manager> find the device that you do not want your computer, right-click and select Properties> under the Power Management tab, uncheck the option “Use this device to a computer” box.

4. Click Disable sound

If you have speakers on your computer, click on the sound effect is heard every time you made a choice, you can be very annoying. To disable this:

* Right-click on the speaker icon in the lower right corner of the screen> select Tones> scroll down and select “Start navigation”> in the drop-down menu “Sound”, select “No”.

5. Folder View Change

If the size of the icon view to come back later, you may find that the return to the original size. To change the size and type must be specified:

* Control Panel> Appearance and Personalization> Folder> View> down, and check “Remember each folder view” option.

Sometimes the installation folder may be damaged, if so, please click here:

* Start> type “Regedit”> Then navigate to HKEY_CURRENT_USER> Software> Classes> Local Settings> Software> Microsoft> Windows> Shell> click on “pockets”, and select Edit> Delete> Yes, remove the key and BagMRU, then reboot.

To avoid problems in the future, to increase the cache folder to see:

* HKEY_CURRENT_USER> Software> Microsoft> Windows> Shell> double click “BagMRU size” select “Decimal” and make it 10000. This is more of RAM, but in future it is necessary to prevent memory loss.

6. You can not say what would happen if I Defrag

A small bar is located in the Windows XP option to defragment the hard disk has been removed in Vista. This means that you do not know how long it will need to defragment. Unfortunately, the only real solution is to use third-party applications, such as power defragmenter.

7. Removed desktop icons

If you accidentally deleted a useful desktop with Windows Vista makes it easy to get them back:

* Right-click anywhere on the desktop> select Settings> then click “Change Desktop Icons” on the left pane, under the task> check the box next to the icon you want to restore.

8. After disabling the automatic reboot in Windows Update

Once your computer has installed the latest update Windows, you are prompted to restart your computer. You can restart a delay of 10 minutes to four hours, but you can also disable it forever. To do this, see:

* Start> type “CMD”, rather than press-Enter, instead press Ctrl + Shift + Enter> Type net stop “Windows Update” to automatically restart.

9. Fast Registration

If concern for the safety and speed that you are the only person using your computer, this may be the idea of applying for a password. To do this, see:

* Start> panel type userpasswords2 ‘> then uncheck the box next to “Users need a username and password to use the equipment.”

For me the only real problem with Windows Vista compatibility with audio and audio-visual products and software. If you have no need for this kind of applications, and that these parameters should be fine with Vista.

DISK Defragmenter
• It is a program used to sort or sort out the files that are not neatly arranged. Usually these sort pogram files or file based on the priorities that are often used. After the defrag, the files are neatly arranged.

• Files that fall apart in a drive will prevent the system working, and in the drive capacity is usually required in order to empty the system does not easily damaged, capacity minimum is usually 15% of original capacity. In this case, the virus will be known as the file and follow made.

• Benefits of Disk Defragmenter:
1. Keeping the hard drive to run faster

1. USE ASCII Character
ASCII character can be used to protect files and folders from virus attacks. Technical quite popular and powerful. Up to the time this article was written, the author know, all the computer viruses that spread all over the world there is no one who has to file with the protection against infection, but of course with the virus that made programming techniques that will be able to better penetrate this protective defense.

Example Usage:
- Technical Writing ASCII Character:
In the default keyboard, the Num Lock condition On / On, press and hold the “ALT”, and write Figures / Figures combination with the Numeric Keypad appropriate formula writing ASCII Characters, and then separated the “ALT”.
Example:
ALT + 1 = ☺
ALT + 2 = ☻
ALT + 3 = ♥
ALT + 4 = ♦
ALT + 5 = ♣
ALT + 6 = ♠
ALT + 7 = •
ALT + 8 = ◘
ALT + 9 = ○
ALT + 10 = ◙
ALT + 11 = ♂
ALT + 12 = ♀
ALT + 13 = ♪
ALT + 14 = ♫
ALT + 15 = ☼
ALT + 16 = ►
ALT + 17 = ◄
ALT + 254 = ■
ALT + 30 = ▲
ALT + 31 = ▼
ALT + 21 = §
ALT + 63 =?
ALT + 168 = ¿
ALT + 64 = @
ALT + 0169 = ©
ALT + 0153 = ™
ALT + 241 = ±
ALT + 247 = ¸
ALT + 0188 = ¼
ALT + 0189 = ½
ALT + 0190 = ¾
and so forth.

- Technical:
1 Create Folder, Rename, and by placing ASCII Character at the beginning of the folder name you have, eg: ♥ myDocuments,
or you can Name as you remain in accordance with the procedures / instructions above, for example:
♥ ☺ ~ ~ Rebert% twØrk ® ã ² ~% ~ ☺ ♥

- Finally, place the Files you want to protect in the folder.

2. Compress the file with Compressor with PASSWORD PROTECTION
Compress any data that you want to use protection WinRAR or WinZip or similar programs with other protection to give first compressed data with password.
Viruses are not only the difficulty / failure to compress files with password protection, but even the latest anti-virus does not / has not been able to penetrate the file when the file scanning.
Do not forget that the difficulty level of the structure of your password (a combination of long and short character password) influence the level of difficulty of piercing the file is protected.
Therefore, the long and varied structure of the characters a password (a combination of letters, numbers and special characters / symbols) will have the level of protection stronger.

3. Permission UAC SET WITH ACCESS TO PREVENT / WRITE / DELETE FILE AND FOLDER (VISTA)
On Windows Vista, we can set the security configuration on each file or folder with files in it using the Access Permission.
Technical protection files and / or folders:
- Right Click on the file and / or folders to be protected,
- Select and click Properties,
- Click the Security tab
- You add the single Users or the Users Group will be limited access (write / modify / copy / delete / etc.) On the file that will be protected,
- Set Permission according to your wishes.

Note: This protection technique is required Administrator access rights and UAC (User Account Control) is active for its implementation.

Another way to minimize the virus into the computer is how to enable the Guest user, and login with the guest user.Because the Guest user is not directly then we will kill the registry, because the virus will always be to infections this registry file and change the value in it.
You can also minimize the virus into the computer with anti virus always update regularly.

or

STOP: 0xc0000221. Bad image check sum, the image user32.dll is possibly corrupt. The header check sum does not match the computed check sum.

Error usually occurs on Windows XP on the system during the startup of your computer, and when a driver has been important ‘missing’ or corrupt. This error will appear if there is a file “User32.dll” a corrupt or ‘missing’. To fix this error, you can change the file that is corrupt. If you do not do this, you must reinstall the operating system back your Windows XP. To restore the damage or loss of a driver file User32.dll, I can see the following:

* You can enter the Windows XP installation CD into the CD-ROM and booting the PC to make sure booting from the CD come.
* In the “Welcome to Windows”, and press the letter R to open the “Recovery Console”. When the Recovery Console has been shown, you can run a command that is in the lower one by one, press Enter and type each command, and also change the name of the driver driver_name with the previous error.

cd windows \ system32 \ drivers
ren drivername.sys driver_name.old
copy F: \ i386 driver_name

Note: Changing the F: drive with the letter of the CD-ROM drive.
Finally, you can exit the Recovery Console, remove the Windows XP installation CD and restart your PC

If the error occurs in the user32.dll file, you can run the following instructions in the Recovery Console:

cd windows \ system32
ren user32.dll user32.old
expand F: \ i386 \ user32.dl_ c: \ windows \ system32 \ user32.dll

If you still can not fix the error with the instructions above, you can repair your installation of Windows XP. You can do this by selecting the option that is on display “Welcome to Windows”, which appear when booting a PC from Windows XP installation CD.

To prevent software or drivers that can make your computer system error, you can run several prevention. You can use the antivirus and antispyware tool with the latest update and run the scanning routine to ensure that your PC is not infected with the virus or the like. You should also keep the PC and your work environment, with open and clean your PC and the periodic check that all connectors and the card was seated properly on the motherboard. Still, most importantly, make sure you can register your Windows error free registry cleaner tool with a reliable and efficient. and following article for the error in the taskmanager (to enable taskmanager, cmd and regedit)

solutions are not necessarily 100% able to complete the problems on the computer affected by a virus program. virus programs also sometimes does not turn off all of that. because each virus has a different logic program and a different destination, as well as systems that use the virus. but most of the virus program is disable “Task Manager”, CMD (Command Promt) and Regedit. why? because, using taskManager we can see all the processes running on the computer, and using “Task Manager” usually user computer can turn off the virus process. it is one of the reasons for a virus to disable Task Manager. as well as regedit and CMD both have important roles to make the settings in the windows.
