Method one: Cancel window boot screen
Please go to My Computer, Tools at the top, Folder Options and then View; tick “Display contents of system folders” and “Show hidden files and folders” within “Advanced settings”. And then go to search the file “Msdos.sys” under drive C. Once you have found it out, right click it to select Properties and then cancel its “Read-only” properties, then open it with Plain Text Editor, adding: logo=0 at the end of the “Option” paragraph. Hence, the Windows boot screen will not load when starting up the computer, speeding up computers at startup.

Method two: Remove some unnecessary services
Normally, Windows will automatically start some services that do not need by lots of computer users, or some programs installed on the computer will also automatically add some entries to run at windows startup, which will only waste large amount of when starting up the computer. So it is time for you to turn off these unnecessary services. Here is what you can do: go to Start -> Run -> type “msconfig” and press “OK” to access Startup, and then uncheck the entries which do not need to automatically run at windows startup. After the modification, the computer will be much faster, at lease more than 10 seconds when starting up.
  
Method three: Clean Windows registry
It is know that Windows registry is the main soul of the operating system, which affects the he proper running of the computer. But while windows system and other processes are running, it is unavoidable that some registry items are generated and rewritten constantly. So it is necessary to clean Windows registry to remove the invalid and useless registry keys from the computer, keeping the registry impact and speeding up the computer. It will be very easy for you to download some free registry cleaners from the Internet for your Windows XP.

Method four: Maintain hard disks
When installing programs or storing files on the computer, a complete file will be scattered into parts and then located in multiple places when it is impossible for the computer to locate a same content to a single place, which means that these parts has to searched and then put together before being used. The more fragmented the hard disk it, the more time it will cost in starting up the computer. So it is necessary to maintain the hard disks regularly so as to gain better access to the data, which in turn solves the slow startup problem. To defragment the hard disk, you can simply use the built-in “Disk Defragmenter” option within System Tools.

A simple disk defragmentation helps you reassemble all parts of a same content to stay at a single directory contiguously, making it easier to be assessed. Thus solves the slow startup problem for your Windows XP. If you have never run a disk defragmentation before, defragment it right now with this power defrag utility— Advanced Defrag right now. It will help not only speedily defragment the Windows XP, but also greatly speed up your computer.

In conclusion, the above four tips are what you need to do in order to solve the startup problem like Windows XP slow to start up. And it is necessary to form a good habit when using the computer so as to have an enjoyable computer life, and disk defragmentation is the first one you need to do, in my opinion.

Lots of XP users prefer to use the hibernation function for it will save the time to turn off the computer. But please note that there will be a file named hiberfil.sys generating when the computer goes into hibernation mode. Normally, hibernation takes everything in memory and writes it to your hard drive as the hiberfil.sys file, that is, the hiberfil.sys will be about 512MB if you have 512MB of memory and around 1GB if you have 1GB. When the computer is restored to normal mode, Windows XP will not automatically erase this file but leave it on the hard disk intact, taking up large amount of disk space. If you have ever carefully looked through the defragment analysis report when defragmenting your XP computer, you will find that there are some files that cannot be defragmented, and one of them is hiberfil.sys file, which becomes a stumbling block of a thorough defragmentation but not only a waste of hard disk space . So it is time to delete it from your computer without consideration in order to ensure a thorough XP defragmentation and free up more available free space.

Normally, this file is located hidden under C:\, and we can manually delete it from the computer. But it is recommended that you can use the below method to automatically delete it: go to Start, and then Control Panel and run Power Options, click on Hibernate tab and uncheck “Enable hibernation”, click Ok to save the settings. Then, the generated Hiberfil.sys file will be automatically removed from your computer and you will get back your hard disk space.

After the removal of this file, you can go to defragment you computer. Believe me, it will help you much faster defragment your XP computer. But this is not enough to ensure a thorough and faster defragmentation. If you want more detailed information , please be patient to read through this article.

When defragmenting windows XP, there are many things that we can do to ensure a complete and fast defragment process, Here are some what you can accomplish:
1) Run a Disk Cleanup before the defragment process: open My Computer -> right click the drive to be cleaned up -> Priorities -> press Disk Cleanup within the General tab to begin the process.
2) Run an error-checking before the defragmentation: open My Computer -> right click the drive to select Priorities ->Tools -> Error-checking.
3) Turn off other running programs (or boot the computer into safe mode) before the defragmentation to prevent some unassociated interference.

With the steps above, it will be much faster to defragment your Windows XP computer, but if your hard disk is as large as 300 GB, it seems to be a little difficult (or terrible) to defragment it with windows built-in defragment utility for it will take a very long time to finish the whole defragment process. For me, I prefer to defragment my XP computer with a professional defrag program like Advanced Defrag to ensure a thorough defragmentation effectively.

In conclusion, a removal of the Hiberfil.sys file before the disk defragmentation is necessary to ensure a thorough defragmentation for Windows XP. But in order to save both your time and energy, it is wise to defragment it with a special designed defrag utility, Maybe you can click here to find something valuable.

As it is known to all computer users that it will cause more time to access a data when it is saved in different places. Moreover, when booting up the computer or running a program, it needs some time to load itself, if combines with the time to access the required data from multiple locations, it will be more difficult to get a faster computer. Besides the delays in starting up the computer, sometimes, fragmentation on the hard disk will cause problems in accessing files and loading pages, difficulties in accessing and sending emails, phenomenon of computer freezing-ups and crashes. If this happens on a server which is accessed by thousands of PC users, things will be more serious because the accessing time to a specific application will be double or more. At this time, the usage of virtual memory will become a real obstacle to system performance.

So it is necessary for us to defragment the Windows XP regularly in order to optimize the entire PC performance. What is more, in windows XP, virtual memory is the memory used as part of hard disk space, which has nothing to do with the actual physical memory. When a process runs out of the virtual memory that belongs to it, even if there is large amount of physical memory, there still comes the phenomenon that no memory can be allocated. In windows XP, what virtual memory corresponding to is virtual memory page file: PageFile.Sys. With the creating and deleting of the page file, fragmentation will occur and grows to be a serious problem.

So the best way to solve the optimize Windows XP is to make good use of the disk defragmentation and the virtual memory. By default, there will be several drives in an operating system, so it is recommended that you can remove the virtual memory page files to a drive which is not frequently used. You can right click My Computer ->Properties->Advanced->Performance -> Settings ->Advanced tab within the popping –up window -> click Change within Virtual Memory. Here, you can remove the temporary paging files to any drive you like. What you need to do is first highlight the drive, and then custom the initial size and maximum size, and then press Set button to save the change. But if you want to delete the paging files from a specific drive, you can directly set both of the initial maximum size to zero.

In this way, you can defragment your Windows XP quickly with the Disk Defragmenter, which will more or less make the files on the computer locate at the same single place, and there is no need for the hard drive to search for several pieces when a file is requested, thus increase the computer speed dramatically. But here, it is recommended that you can defragment your XP computer with a professional defrag program to ensure a smooth and faster defragment process, optimizing PC performance.
