I am using a brand new embedded system that runs Windows 7, and it has spontaneously installed the Update KB3020369.

I'd like to get rid of it as it is eating up precious disk space, but the standard procedures (via the control panel or the wusa command) do not work. You get the message 'Update for Microsoft Windows (KB3020369) is required by your computer and cannot be uninstalled'.

Do you have a solution ? (I found many posts on the topic on the Web but non was conclusive so far.)

    have you tried wusa /uninstall /kb: 3020369 /quiet /forcestart Else do system restore. However this is not a solution to your systems performance – pun Jul 20 '15 at 16:41
  • The Update does not appear in the restore list. The Update does appear in the Control Panel, but there is no Uninstall option. MS made that on purpose. – Harry Cover Jul 20 '15 at 17:20

    Windows System restore will remove it. – Moab Jul 20 '15 at 17:53

You can't (officially) uninstall this update, because it is marked as permanent in its manifest file (metadata)

<package identifier="KB3020369" [...] permanence="permanent">

Microsoft does this for all servicing stack updates. You could remove this permanence entry, but I had issues in the past after removing older servicing stack updates. So don't try this.

What do you mean with eating up space? run TreeSizeFree to see which folder uses most space.

  • I mean that free space decreased by 1 to 2 GB after the install, which is significant in my context. – Harry Cover Jul 20 '15 at 18:47
  • I tried to find this entry in a manifest file, to no avail. – Harry Cover Jul 20 '15 at 19:19

    if you run the tool as admin, you may see that System Volume Information has growm. This is the location of the system restore points. So delete older ones: windows.microsoft.com/en-US/windows/… – magicandre1981 Jul 21 '15 at 4:00
