    How to prevent writing to a specific registry key?


    So changing registry strings is a pretty common tool around here and something ive done pretty comfortably for a long time. Messing with registry permissions goes above my head and is quite a bit more risky. AFAIK with my limited knowledge ACL's and the like is quite a bit more risky. I'd like to make this change as limited in scope as possible, and entirely reversible. Automatable via script if possible would be even better. Dropbox. The bane of my existence as far as overlays go. Due to windows longstanding limit for overlay icons and its poor means of prioritization, i've had to go into the registry to manage them. 90% of the time this is due to dropbox updating and leapfrogging everything. This fact in and of itself keeps me from enrolling in the dropbox beta builds as that would mean needing to self-modify even MORE frequently. So in short, how can I remove write permissions to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers and then un-do it when/if the need arises?

    :)

    Prevent specific app writing on specific folder

    There's a 3rd-party app I have that let me connect to servers to play warcraft 3 with others. It is a great alternative for battle .net. But I am annoyed and worried of what it does. It generates random files inside system's "Windows" and "SysWOW64" folder.
    It's just weird that they are doing this. It makes me worry. Especially, they are writing on a system folder. Any help would be much appreciated!
    I already tried changing its permissions by going into the properties of the ".exe" >> Security Tab >> Advance >> Changing owner from "Administrator" to "User", and changing permissions from "Full Control" to "Read and Execute". Also removed other Principals. After all of that, it could still write on the system folder :/

    Here's some screenshot of what it generates.

    Windows Registry Writing Issues

    I have a VB6 app that reads/writes information to the windows registry. everything works fine on every version of windows up to windows 10. On windows 10, I have had the occasional issue (sometimes after windows 10 updates) where the app cannot read/write
    to the registry key (under hkey_local_machine). One time the user account had to be deleted and recreated to give me access to the registry key. The other I was able to run the app as the administrator once and then revert to running it without administrator
    privileges and that seemed to fix the issue with writing to the registry. Why does this happen? How can it be prevented? Thanks for any help.
