    Realtek Update via Windows Update used nearly 10gb space.


    An update for Realtek Audio was offered as an optional update a few days ago.

    I went ahead and installed this with the install taking almost 10 minutes to complete. Before the install my free space was around 55gb. Following the update it is nearer 47.6gb. I have run a full disk clean (including system file clean up). Nothing has been freed up.

    Looking in the Windows driver store shows file after file after file all with the date I installed the update. Each of these files is between 60mb to 250mb in size. And there are dozens and dozens of them.

    I'm tempted at this point to simply undo all these changes via a disk image and to simply hide this update. I also haven't been able to find anything out about this update. The MS link for further information that always accompanies updates says the further info feature is not available for this one. Device manager shows no 'roll back' option for any of the Realtek Audio.

    So just what has this update done ?

    Glad I saw this. I haven't installed it yet.

    I installed this update, but only had a total of about 63 files (see attached screenshots - the entries on 03/29/2015) and no noticeable decrease in disk space. I can't imagine what your problem might be.

    This update significantly upgraded my Audio Manager with "bells and whistles". Kind of fun to use now.

    I am running HP Pavilion p6230F with Windows 8.1 x64 (upgraded from Windows 7 originally)

    John, do you mean you are seeing something like this for the audio manager ?

    I can't recall ever opening this before.

    The free space issue is weird but its actually something I see to a greater or lesser extent with most updates. For example a Flash Player update knocked perhaps 1gb off the free space. The really strange thing is that it comes back after a few days. I've even commented on this before. Post #13 here.

    MS released a new update for IE 11 today KB3025390

    This time I made a disk image after the Realtek update and my Acronis file size has jumped from around 15gb to 17.5gb which suggests the usage is real. I might wait then and see if the free space alters.

    After sleeping on it I decided to restore back and hide the update. There is no way that a 66Mb update should take this much space, goodness me, the whole OS plus quite a few programs plus user data only takes 25Gb. To have 7.5Gb consumed by one update is ridiculous.


    Free space back up at 55Gb (from 47Gb following installing this update). Compare this to the image in post #1

    Gigabyte stopped producing RealTek audio HD driver updates for my motherboard years ago, so I started getting them directly from RealTek. Then, I stumbled upon the station-drivers site -- which offers driver downloads for free. I have since been using that site and regularly update the RealTek drivers without any problems. Since my drivers are then always the latest, I don't get offered updates through Windows Update.

    I've just registered on this forum after coming up with the same problem as the OP's.

    I had a few static pops in my audio now and then, so decided to go with the optional update of the realtek audio drivers via Windows Update to see if they got cleared up. I noted before the install my HD space, then noticed afterwards that over 7Gb of space had been consumed since the update (checked right after). Unlike the OP, I was able to roll back the driver when logged in as my admin via Device Manager, which worked (it's back to the previous version). However, the space has still not returned. Hopefully the poster who says that this might sort itself out in a few days is correct, because it's ridiculous that a 66Mb update can expand to over 7Gb...

    Indeed, better to update manually, leaving it to WU is as bad as using 3rd party driver updater.

    Probably a scheduled cleanup did the trick, it can be done manually as well.

    That's interesting to hear Gort. For me the plot thickens (although because everything works OK I'm not going to pursue this).

    It turns out that I can't even locate any Realtek control panel, either on the restored version or the updated one. All I have in device manager is 'Dell Audio' which is a surprise because when I installed W8.1 I did it as a clean install but I did get some drivers and so on from the Dell site. I installed all those first before ever firing up Windows Update. I'm wondering if the Dell versions are modified files... how else would it know in control panel that this was a Dell... and that maybe the Realtek update contains files for a whole host of possible versions. Just thinking aloud there.

    A web search for 'no Realtek control panel' shows its a common issue though. All does work well as it stands though and so I'm going to go by the old adage of 'if it ain't broke don't fix it'.

    If your free space returns please come and update this thread

    Currently doing a Disk Cleanup, which found that Windows Update and the Device driver packages were taking up nearly seven gigs (the latter taking up six gigs of the space). It's taking a long time to complete (seems expected on Win8.1), but already my space has returned to, more or less, what it was before. When I searched on the Net, I found Regain hard disk space by using Windows Update Cleanup in Windows 7 and 8.x, which explained a bit about the Disk Cleanup utility that's included in Win8.1.

    @ TairikuOkami - Thanks for your suggestion, but I found the link I mentioned above before your post. I'll certainly keep it in mind if this happens again. Cheers.
