Even if you could share the Program Files folder, you probably
couldn't share programs across the LAN. Most programs have to be
installed on a computer to run on that computer. The installation
process copies necessary files to the computer and creates necessary
entries in the system registry database.

By default, Windows XP (when installed on an NTFS disk partition)
blocks network access to the Program Files and Windows folders and to
individual users' folders within Documents and Settings. I don't know
why Microsoft designed it that way.

You can share subfolders within those folders, e.g. you can share
"C:\Program Files\Outlook Express" or "C:\Documents and
Settings\Username\Desktop" and access that folder from another
computer on the network.

If you have Windows XP Professional, you can permanently disable
simple file sharing, which removes those sharing restrictions:

1. Open My Computer and click Tools | Folder Options | View.
2. Scroll to the end of the advanced settings.
3. Un-check "Use simple file sharing (recommended)".

If you have Windows XP Home Edition, there's no easy solution. The
safest thing is to share individual subfolders, as mentioned above.

You can re-install the operating system on a FAT or FAT32 disk
partition -- those disk formats don't have any sharing restrictions.
However, that would lose the benefits of NTFS, which is more reliable
and efficient and can use larger disks. You'd also need to re-install
all of your applications.

I've heard of two possible solutions for XP Home Edition on an NTFS
disk partition, but:

1. They're un-supported, un-documented, and un-tested by Microsoft.
2. There's no guarantee that they'll work.
3. They might cause data loss or corruption.

I haven't tried them, and I don't know whether they're safe. If you
want to try them, at your own risk:

1. Back up your important data first so that you can restore it in
case of problems.

2. Run System Restore to create a restore point that you can go back
to in case of problems.

Here they are:

1. Start Windows XP in "Safe Mode with Networking" (which temporarily
disables "Simple File Sharing"), share the desired folder(s), set the
permissions, and reboot normally, or:

2. Follow the procedure shown here:
