How to Improve PC Performance.

How to Improve PC Performance.

Tip No. 1

CLEAN UP YOUR WINDOWS REGISTRY

This is an essential, but often overlooked, task to improve PC performance. In fact most PC users are unaware of the necessity to regularly clean the Registry as Microsoft does not include a cleanup tool in any version of Windows.

Every time a program is installed it makes changes to the Windows Registry - a huge internal database of Windows' settings. Virtually all Windows programs, and Windows itself, store a massive array of information inside the database. These thousands of entries control the behavior and appearance of virtually everything on your system.

Changes to your PC system are not always handled correctly in the Registry, leading to conflicts and the slowing down of your PC. Over time this leads to a bloated and possibly, corrupted Registry. Reasons for this include:

- frequently installing or uninstalling programs
- removing a program which leaves traces behind
- leftover entries from a hardware uninstall
- unused drivers on your system
- Spyware or similar programs that reappear every time you reboot

You can edit the Registry manually using a Windows program called Regedit, but this is really a job best left for hardened PC experts.

Thankfully, programs are available that can clean up your Registry automatically to help improve PC performance, such as "Registry Optimizer '06". This scans your Registry, looks for entries that are redundant or invalid and lists them so that they can be corrected with one mouse click. As an added bonus, to improve PC performance, it runs automatically in the background every time you start your PC. You even get a complimentary PC Windows Health Check.


Improve PC Performance Tip no. 2

EMPTY THE RECYCLE BIN (Frequency = Weekly)

Regularly empty Windows' Recycle Bin.

This will release hard drive space and help improve PC performance.

When you choose to delete a file, rather than removing it completely from your computer, Windows first puts it into the Recycle Bin. This gives you a second chance, as it means you can restore flies from the Recycle Bin back to their original place on your computer.

To ensure optimum PC performance, empty your Recycle Bin weekly (or even daily). To do so, right-click the Recycle Bin icon on your desktop, and choose Empty Recycle Bin.


Improve PC Performance Tip no. 3:
REMOVE PROGRAMS (Frequency = Monthly)

Installing programs is easy - but once you have, it's just as easy to end up leaving them languishing, forgotten, on your hard disk.

Most programs come with their own uninstaller. You'll find this under the program's entry in All Programs, from the Start menu.

If the program doesn't come with its own uninstaller, open Control Panel from the Start menu, and double-click Add/Remove Programs. Your PC will pause briefly while it gathers a list of all the programs you have installed.

Once it has done so, find the program you'd like to get rid of, click it and then select Change/Remove.

Be aware that some programs leave uninstalled traces all over the Windows Registry! Therefore, to improve PC performance after an uninstall, it's essential to clean the Registry.


Improve PC Performance Tip no. 4:
RUN DISK CLEAN UP (Frequency = Monthly)

Windows' Disk Clean Up is a fantastic built-in utility that automates regular maintenance tasks to improve PC performance, such as deleting Temporary Internet files, Setup log files, etc.

To start Disk Clean Up, double-click My Computer, right click on your 'C:' drive and then select Properties. Now click Disk Cleanup. Your computer will then spend a few moments analysing itself.

When it has completed the audit Windows will give you a list of areas where it has found files to cleanup. To clean an area, put a tick in the box next to it. To leave something intact, such as Temporary files, just remove the tick next to the item and click OK.

Your computer will then begin the removal process to improve PC performance - this can take some time.


Improve PC Performance Tip no. 5:
DISK DEFRAGMENTATION (Frequency = Quarterly)

When Windows stores programs on your PC hard disk it saves fragments of files in the nearest empty spaces.

This slows down your PC as it has to spend time hunting down the fragments and piecing files together.

There is a simple cure - running the Windows program Disk Defragmenter. This gathers together the fragments of programs and puts them back in the right order.

This makes it far easier for your hard disk to find what it's looking for, enabling programs and files to load more quickly - a sure-fired way for improving PC performance.

To defragment your hard disk click Start, All Programs, Accessories, System Tools and then Disk Defragment. When the program has loaded, click Defragment.

The process can take well over an hour. Because defragmenting your hard disk takes such a long time, you really don't want to go through the process too often.

Defragment your hard disk every 3 months or so - this way you'll get the best results and optimize the performance of your PC.


Improve PC Performance Tip no. 6:
EMPTY THE PREFETCH CACHE (Frequency = Quarterly)

To improve the time it takes to load programs, Windows guesses which files are likely to be needed next and loads them into a pool or 'cache'.

This process is called prefetching, and it generally works well. Overtime, though, the prefetch cache can become clogged with files you no longer need - and that can slow down Windows' startup.

To clear Prefetch, choose Run from the Start menu, and enter Prefetch into the text box that appears. When you've done that, you'll be confronted by a window filled with icons. Press Alt+A to select them all and press Delete.

The cache will quickly refill with links and files that Windows really needs. As a result, your system will feel more responsive and benefit from a PC performance speed up.


So there you have it, 6 sure-fired PC performance tips to revitalize your PC. Now you know how to improve PC performance - simply follow these steps and repeat them regularly.

What is inetinfo.exe?

Inetinfo.exe is a user-mode component that hosts the IIS metabase and that also hosts the non-Web services of IIS including the FTP service, the SMTP service, and the NNTP service. Inetinfo.exe depends on IIS Admin service to host the metabase.

inetinfo.exe is used primarily for debugging Microsoft Windows Server Internet Information Services. This program is important for the stable and secure running of your computer and should not be terminated.

LAN WAN
Definition:LAN (Local Area Network) is a computer network covering a small geographic area, like a home, office, or group of buildingsWAN (Wide Area Network) is a computer network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries
Example:Network in an organisation can be a LANInternet is the best example of a WAN
Ownership:Typically owned, controlled, and managed by a single person or organizationWANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management
Technology:Tend to use certain connectivity technologies, primarily Ethernet and Token RingWANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances
Data transfer rates:LANs have a high data transfer rateWANs have a lower data transfer rate as compared to LANs
Geographical spread:Have a small geographical range and do not need any leased telecommunication linesHave a large geographical range generally spreading across boundaries and need leased telecommunication lines
Connection:one LAN can be connected to other LANs over any distance via telephone lines and radio wavesComputers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites
Set-up costs:If there is a need to set-up a couple of extra devices on the network, it is not very expensive to do thatIn this case since networks in remote areas have to be connected hence the set-up costs are higher
