    $Ntuninstall files (Windows XP Pro)

    Hi All

    I have dozen or so files in the windows system folder it is obvious from the file name they are something to do with uninstalling. But do I need so many and what do they actually do.

    Thanks in advance

    ...if ever you need to roll-back...
    If your HD is so full you have to contemplate removing files from within the Windows Directory (other than .tmp files) : get a biger hard-drive <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    Hi Braddy
    Sorry for the cheap dig. As you have gathered, my real advice is just to leave 'em alone, as I think you will...

    These folders are used to uninstall patches/hotifxes. If you apply a fix from Windows update or Windows download and your system start misbehaving these folders contain the files used to revert to before the fix. I'd second the opinion to leave them alone.

    Re: $Ntuninstall files (Windows XP Pro)

    When you use Windows Update two types of updates installed: the Hotfixes to the OS -- which are the folders you see under C:WINNT and which have corresponding Add/Remove items in the add remove applet; and driver updates, which are usually marked in the update history as being from a third party. For instance, a sound card driver. These driver updates do not install Add/Remove items. Rather they are "roll backable" in the System Properties Device Manager Properties Driver/Roll Back; the actual roll back driver info is stored in C:WINNTsystem32ReinstallBackups.

    To roll back a Hotfix that doesn't work, use Add/Remove. To roll back a device driver that doesn't work, use Device Manager.

    Why this explanation of the difference? Because I find the $NTUninstallQXXXX$ folders you are talking about really annoying and bad design on MS's part. It's bloat. Most of these hotfixes are low level and many are security related and it's highly unlikely that they will cause a problem with your system. Furthermore, as soon as there is a service pack released for XP, then all of the hotfixes -- which were installed individually by Windows Update -- will be rolled into one big patch file which will ALSO have an uninstall item in Add/Remove. Installing the Service Pack will not remove the individual hotfix items. There will then be a possible confusion. What happens (I'm not sure) after installing a Service Pack and then "removing" an individual hotfix? Does it remove? Does it break the Service Pack? INMHO, there's something goofy about how MS is handling Windows Updating.

    Seems to me the Add/Remove item for individual hotfixes should have two buttons: one to remove/rollback the hotfix and one to "Accept" and permanently install the hotfix (which would remove the Add/Remove Item and the folder).

    I'm not recommending this for everyone, certainly not for anyone who doesn't have a full backup, but for the record, I have deleted all the $NTUninstallQXXXXX$ folders and all the Add/Remove items that would roll back those hotfixes without any ill effect. I did so after determining that my system was running properly.

    I have had occasion to use the roll back feature for a driver update which failed and was glad I could. But I've never had to roll back a hotfix.

    For what it's worth.
