Many people who are studying error messages and knowledgebase of microsoft operating system stumbles on this term “commit charge”. But what the hell is commit charge ?
As per Wikipedia:
In computing, commit charge is a term used in Microsoft Windows
operating systems to describe the total amount of virtual
address space for which the backing store is the pagefile.
In laymen’s terms, commit charge is the current amount of used virtual memory. It can be considered the sum total of the RAM and pagefile needed to store the private virtual address space allocated by all running processes, if they actually used all they allocate. Most applications allocate more than they actually use. Memory for program code, DLL’s etc. is not included in this total.
Windows keeps track of the commit charge to make sure that there is some place to store all of this potential data, just in case the running applications were to use all the space they have allocated. The commit limit is the size of RAM, minus some overhead, plus the size of the pagefile. Not all of RAM is available to the commit charge.
The important thing to remember about the commit charge is that it must always be below the commit limit. If it hits the limit bad things will happen, such as application or system failures. Since the commit charge doesn’t represent anything physical it is of little importance to performance.

Mammon slept. And the beast reborn spread over the earth
and its numbers grew legion. And they proclaimed the times
and sacrificed crops unto the fire, with the cunning
of foxes. And they built a new world in their own
image as promised by the sacred words, and spoke
of the beast with their children. Mammon awoke,
and lo! it was naught but a follower.

If you’re using old machine with windows 2000/ME/98 installed then while upgrading to windows XP you can choose to upgrade to NTFS file system. There are many advantages of upgrading to NTFS file system. Besides recent releases of windows are supporting NTFS file system and dropping support to FAT/FAT32 file system. You can convert to NTFS file system while installing windows XP or Vista.
If you’ve already installed windows and want to convert to NTFS file system then you need to use converter tool. Follow the steps shown below to convert your drive to NTFS file system:
1. Open command prompt.
2. Type the following command on prompt:
convert drive_letter: /fs:ntfs
Here you need to replace drive_letter with c: or d: or whatever the letter of the drive that you wish to convert into NTFS. If you converted your partition this way into NTFS then there will be no going backwards. If you wish to back to FAT32/FAT file system then in that case you need to reformat and erase the drive which will remove your data as well. So think before you convert to either filesystem.
