    Lost access to running some programs and full access to C


    Hi all

    I was annoyed by how Windows 8 keeps sharing folders on any network I connect to, so I did some digging on Google and found a post on how to disable network sharing. Someone also mentioned how changing Users Permissions / settings would things further, so I went ahead and changed those (I got a whole bunch of prompts to confirm changes and accepted all of them).

    Now I can only access some areas of my computer but I can't run a lot of programs and I also can't access my C drive when I go to "My Computer" and try opening it from there.

    When trying to access C: I get the following error "C:\ is not accesible. Access is denied"

    Also, several programs aren't running anymore and I get a message saying something like "path not found" (see attachments)

    When I check my User Account (control panel, user accounts) I see myself as "Administrator" but I cant change any settings there either (for example, when I click on the "change your account type" link, nothing happens (no new window opens and no error message).

    I've tried everthing, including installing "takeownership.reg" but I can't even instal that ! (see attachment)

    I've also tried restoring the system to a previous restore point but can access any (including when I reboot using the "Shift" key).

    Any ideas highly appreciated! Please let me know if you would like more screenshots , additional details, etc

    Many thanks

    Hello Gomex, and welcome to Eight Forums.

    If you have not already, you might see if you may be able to do a system restore at boot instead of from within Windows 8.

    Hope this helps,
    Shawn

    Hi Brink

    I've tried that (restart + Shift key) and unfortunately it wont roll back (gives some sort of an error / problem with restore message)

    Any other ideas?

    Thanks

    You could refresh Windows 8 to fix this, but you'll need to reinstall your programs afterwards.

    Hello again Brink

    I read up on refreshing Win 8 and I've a couple of questions, namely:

    1) I don't have an installation disc as I have upgraded from Vista (online)
    2) I read that in case of online upgrade I need to check if I have a certain folder on my C: drive, which supposedly contains some sort of upgrade information but the problem is... I can't open/access my c drive :/
    3) My laptop is old and I can't read the Win serial number on the sticker on the bottom of my machine... does this mean I can't "create" a Windows disc?

    Any thoughts ?

    Thanks again for all your help

    No worries, the tutorial below can help show you how to download a new Windows 8 ISO file.
    Afterwards, you could create a bootable Windows 8 installation DVD or USB with the ISO file.

    Hi Gomex, I'm facing the same issue, but am just holding off from doing a refresh, in case some solution miraculously pops up. Any update from your side so far?

    Hi Clixty

    No, I havent gotten around to doing the refresh yet due to all the programs that must be reinstalled, etc.

    Will probably do so over next few days when I have some free time and let you know. Ive researched this problem quite a bit and Brink's answer seems to be the best solution I have come across so far

    Gomex,

    I just tried something, and am quite happy atm, though it's not 100% returning to original, it's good enough!

    I'm not sure whether you can see your HD and right click on it... if you can,
    Set HD ownership to Administrators, go as far as you can with the "replace owner on subcontainers & objects".

    Enable built-in administrator via elevated cmd :
    net user administrator /active:yes

    log off & log in to built-in admin... and...

    programs working! (at least desktop programs... metro apps don't work)

    I will try creating a new user and see if things are alright there. If the new user is ok, all is good!
