What are those "$NtUninstaxxxx" directorys in Windows?

[Guest Richard Lewis Haggard]

Under my c:\Windows directory I have a bootload of $NtUninstalxxxx

directories, some of which go back for several years. What are these

directories and what created them? I'm running low on disk space - is it

safe to delete them?

Yes, but it's best to *move* them elsewhere or burn a CD, etc., if you're

running low on space. The folders/files are created when you install

updates, and you need them present there if you ever want to uninstall the

patches in question.

Hello Richard,

 

To add to Lanwench's posting

 

Have a look here:

What are the $NTUninstall folders? Can they be deleted?

Good luck

The $NtUninstall* 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.

 

$NtServicePackUninstallIDNMitigationAPIs$

$NtServicePackUninstallNLSDownlevelMapping$

Created when you installed IE7.

If you delete them you will no longer be able to uninstall IE7

 

$NtServicePackUninstall$

Created when you install a service pack.

If you are currently using XP with SP2

then if you remove the folder you can no longer

uninstall SP2.

 

When and if you install SP3 this folder grow in size

as it will contain both SP2 and SP3 uninstall files.

If you have already installed SP3 then I would leave

this folder as is until you are certain that no bugs have

cropped up after installing SP3.

Note: Once you delete this folder you are stuck with SP3

 

Warning: One folder you should not delete is: $hf_mig$

(and any folders that a part of/contained in $hf_mig$)

It is a necessary folder for future updates
