"To clean a PC...", that seems can be a little odd for some, but will know that to keep a powerful computer and to enjoy its capacities, it is necessary to make a small de-dusting. When I say de-dusting, I want to say that it is necessary to check the state and the contents of the hard disk.

For those which read the first part of Optimization 1, they could raise questions because this chapter is almost identical. Indeed, the fact of making a good blow of household on the hard disk makes it possible to increase the performances of the PC. But if you read well, you will find other councils to reduce the system.

The defragmentation of the hard disk.
The installations and successive désinstallations of software, the copies and other joinings of files by-Ci by-there, the safeguards..., all this handling involve a scattering of the data on the hard disk, which resembles Gruyere then. The more the data are split up, the more the response time to open an application or to work will be long. This is why, defragmente is needed regularly the hard disk (in general once by week). Go in start then Programmes, Accessoires and Tools system. Select Defragmente of disc. Choose the partitions with défragmenter.Vérifiez that in Parametres, three boxes: To reorganize the files so that my programs start more quickly and To check the reader as allways are well notched.

Use ScanDisk.
You must, at least once by week, to carry out the ScanDisk software on the hard disk. That makes it possible to detect errors of the reader and to repair them. It n’ d’ is not necessary; to carry out a complete scan, except if you l’ did not make for a long time.

Remove the temporary files and the cookies.
During your surfings, your navigator preserves all the Web pages which you have consultées.Sur certain stations, the size of the file Temporary Internet Files can reach an enormous weight. Made purge it more space will give on the disc. In addition to information of the visited pages, many cookies hides in this file. The cookies are of all small files which help you and also identify you at the time of your surfing on a site. But sometimes, the sites which send them their requests anything else: to know which you are, which you do on the Net and what there is on your station. In Internet Explorer and choose Tool-Options Internet and click on the General mitre then on the deleate button the files in the part temporary Fichiers Internet. In the mitre Advanced on the level Safety, notch the Vider box the file Temporary Intenet Files when the navigator is closed.

Clean the base of register.
As we saw, the base of register holds all information of the system like those of the software. If you installez/désinstallez programs, the system must theoretically erase any trace of this software. Moreover, the base of register keeps the traces of documents opened, moved, safeguarded etc... To clean it, use the free utility RegCleaner which analyzes all the short cuts stored in this base and checks that they lead to an existing file. That results in to reduce this base and to accelerate its loading with starting. In addition to doing housework in the base of register, RegCleaner allows you to know all the software installed, even those which are hidden as well as the programs which are with the starting of Windows.

Check the applications which are with the starting of Windows.
Certain software which you install launches in all impunity to each starting of Windows. This slows down considerably the starting of the system and the fact of not making them start makes it possible to gain a little power while releasing from the memory. I would advise you to keep only your anti-virus like your parefeu with starting. Go in Start-Carrying out and type msconfig. In the start shutter strip the software which you know well and who should not be with starting. Attention, do not strip anything because that could harm the correct operation of Windows.

Make hunting for the viruses.
One can only point out it. If you are connected to Internet, imperatively install anti-virus on your machine. To know some more, consult the complete file on the viruses and the anti-virus ones.

Seek the spies or spywares.
The spywares are small programs hidden in other applications or which settle without your knowledge. They épient least the gestures than you make and return information via the Net. It also can upgrader and there, to make beautiful breaches on your navigator and to let with leisure the pirates come in their turn. The only thing to be made, to install a software which makes hunting for the spywares of the type AD-Aware SE Personal which moreover can be updated regularly.

Make updates of the system as well as pilots of the peripherals.
The computer evolves/moves through the updates:
To update Windows via Windows Update (Finely To start), makes it possible to have a more stable and surer system against the attacks of Internet. The function Windows Update will connect you on the site of Microsoft which will analyze your configuration and will suggest you the updates necessary. Make also the updates of the pilots of the peripherals. There will be less conflicts and better performances. Check the model of your graphics board, chart its or printer..., then defer you on the Web site of the manufacturers. Have a maximum of choice, on the Touslesdrivers.com site.
For the software, seek the patchs which stabilize and solve the quite specific and identified problems. For the plays and the multi-media one in general, think of installing the last version of DirectX. For Internet To explore, put the plugin java of SUN which is more stable than that of Microsoft. Also think of installing the last version of the plugin Flash of Macromedia.

Erase the useless files.
Go in start/tools system and clean of disc, there you can choose the files which you want to remove.
All the files carrying extension .SHD, .TMP, .BAK, .OLD, .GID, can be removed without hesitation. You can also remove the contents of the file \ Windows \ Applog, it contains only information on the installation of the programs which are already installed, and those are recreated automatically if need be. If you do not see it go in the Options of files and notch the see box the hidden files.

Empty the dustbin.
It is as for at home, it is practical to empty it regularly...

Uninstall software or plays which are not used any more.
To gain place on the hard disk, désinstallez the software or plays which are not useful to you any more. To increase the disk space, you can also eliminate the software from Windows which either are installed, or préinstallés. Indeed, Windows installs programs which often, are not known people, or then useless for some.
Go in the Control panel and open addition/remov of programs and choose the Installation mitre of Windows. Choose a subject and click on Details. It is then enough to strip the programs desired for the désinstaller.

Zipp documents.
Still to gain place, you can zipper your working papers, your images ..... If you want to keep sound files on the PC, think of converting them under formats compress. For example for a music in format wav of 10 Mo, it can be encodée in format mp3 for a weight of 1 Mo. I do not speak to you about the bitrate, more it is small and more the file is light.

Gain even more place.
Make external safeguards of your documents, plays, musics etc.... Then, once the documents safeguarded on CD-R, for example, remove hard disk.

Then comes "manual" cleaning from the PC.
