If these versions of NET Framework are all
on your PC they most like where installed as part
of one or more software applications you installed.
I would not remove them.
If you need to free up some space on your hard drive
then read on:
First use Windows 'Disk Cleanup' to create more space on your C: drive.
Description of the Disk Cleanup Tool in Windows XP:
http://support.microsoft.com/kb/310312
Next: Empty the Recycle Bin.
If you recently installed Windows XP Service Pack 3:
Look for an odd folder name which is located here
C:\WINDOWS\SoftwareDistribution\Download\cf8ec753e88561d..........\
Note: the apparent random set of letter and number may vary from my
example above but whatever the name is, it will be more than
600MB in size and can be safely deleted.
You may also see a number of other folders or files located in the:
C:\WINDOWS\SoftwareDistribution\Download\ directory
They also can be deleted.
You can also free up more disk space by reducing
the number of 'System Restore' points:
Select Start/Control Panel/System, then in the System Properties window
click on the System Restore tab.
Next select the drive letter where Windows is installed (usually C
,
Then click on the Setting button
Now in the Drive Settings window move the Disk space usage slider to the
left to reduce the amount of drive space System Restore points will use.
This will remove some of the older restore points and free up some space.
Disable Hibernation and delete hiberfil.sys file (If you have it enabled):

If you are using IE7 and then installed SP3 read the info below.
IE7 users will find the folders listed below on their hard drive:
$NtServicePackUninstallIDNMitigationAPIs$
$NtServicePackUninstallNLSDownlevelMapping$
They are needed to uninstall IE7. However, if you installed IE7 and
then installed XP SP3 you can no longer uninstall IE7 and these
folders can also be deleted.
Note: The recommended procedure before installing XP SP3 is to
uninstall IE7, then install XP SP3. Now you still have the ability to
install and uninstall IE7.
Next if you still need more space:
Remove the files used to uninstall updates to Windows
These folders and associated files in these folders are safe to remove,
however once deleted you will no longer be able to un-install a patch or
update that was associated with the deleted folder/files.
I would keep the most recent set (last two months just in case) of folders
and delete the older updates.
As a safety net I burned these folders to a CD before deleting them.
These files are located in the Windows folder and have folder names
like $NtUninstallKBXXXXXX$.
They are hidden folders so enable viewing of hidden files in Windows
Explorer.
Warning: One folder you should not delete is: $hf_mig$

How to delete unused folders and files located within the $hf_mig$ folder -
Part 1
http://www.pagestart.com/hfmigpart1.html
(Using this tip will get you about 100MB or more free space)
If you upgraded your PC from Windows 98 to Windows XP.
The $Win98UpdateUninstall$ can be deleted.
You can reduce the size of the Internet Explorer Disk Cache:
How and Why to Clear Your Cache:
http://www.microsoft.com/windows/ie/ie6/using/howto/customizing/clearcache.mspx
Just follow the instructions but instead of increasing the size
(as stated in the article) decrease it.
Can I move or delete my C:\I386 directory to free up some space?
See:
http://ask-leo.com/can_i_move_or_delete_my_i386_directory_to_free_up_some_space.html
Note: C:\i386 is not to be confused with the
C:\Windows\ServicePackFiles\i386 folder which should not
be moved or deleted as Windows File Protection needs those files
Finally: Check the Recycle Bin one more time and empty it
if necessary as some of those files you deleted in the steps
mentioned above may find there way into the recycle bin.

(See the section titled: Move LIS Cache folder to a new drive location)
Note: If your computer already had more than one hard drive or partition
when you installed MS Office, Office will place the MSOCache on the drive or
partition with the most available free space during the install process.
