    Can not make changes in User Control Panel (UAC)

    I am new to here and not sure if this thread maybe already solved. So I will be as detailed as I can.

    My wife and I are both using Windows 10 Pro laptop pc's.
    Both of our pc's in the control panel can not access user accounts or anything. Normally a UAC window would pop up and would click yes or no to perform certain tasks but it does not.
    If we was to install a program such as CCleaner or run CMD as admin that little UAC window will pop up.
    I have googled and tried using a helper from Microsoft website that was to supposedly fix the issues but did not.
    We both have ran Malwarebytes and Avast and nothing was found.
    Windows did have updates and not sure if the updates have anything to do with it.
    Could use some help on this please.

    Have you turned UAC off completely?

    We have done nothing to the UAC I don't even know where to even go do that at. It seems as if it turned itself off? Basically anything that would require certain permissions I can not give that permission since the window will not open or pop up to allow.

    Do you have any relevant system restore points you can use that would allow you to restore your system to a previous state?

    Then click the highlighted item found, click System Restore, click Choose a Different Restore Point and post a screenshot of the result

    If not, there is a program you can use to restore permissions, but that's making an assumption.

    I can get to the user accounts panel. I just can not click on anything to make any changes since that little box that pops up asking me for permission will not appear.

    Do you have any system restore points you can use?
    Note: you can also start system restore by booting from a Win 10 install medium e.g. - click 'repair your computer' and navigate to System Restore.

    (You will only have some if you have enabled System Restore at some point).

    System restore only goes back to the 22nd and this seems to have been going on longer.

    It seems strange both PCs are affected similarly. This suggests the same thing may have happened to both- you might consider what similar thing has been done to both.

    I suggest you try's repair tool (free). This has a number of cautious steps to work through- use these appropriately as far as the deficiencies you are experiencing allow.

    I'll suggest some of the repairs- I have no idea if this will help to solve your actual problem.

    Now we strongly and repeatedly urge people to use disk imaging routinely- as most regular contributors here do. (See my signature). This gives you a way to restore your PC to a previous working state without technical help- even if your disk fails.

    I suggest you create your first disk image before attempting these repairs. (E.g. Macrium Reflect (free) + external storage for disk image sets). There is a video and tutorial on this site, and videos on youtube, and a big help file with the program. repairs:
    I suggest nos 1, 3,10, 32 might be worth trying first- start with no. 32

    Okay I will defiantly look at that site. In the mean time I was still wearing google out and may have come across a fix for now. I am not sure how long it will last or it may last since it might have been a program (free trial) might have messed things up since we had both installed it on our comps.
    I am not sure if I could copy and paste the link in this group but I can copy and paste the text so if someone else has the same issues this might help them in the future.

    1. Press Windows Key + R combination, type put Regedt32.exe in Run dialog box and hit Enter to open the Registry Editor.

    2. Navigate to the following location:

    3. Now right click on the MUI key and select New -> Key. Name the newly created key as StringCacheSettings. In the right pane of this newly created key, create a new DWORD value, name it as StringCacheGeneration. Double click this newly created DWORD to modify its Value data:

    4. In the above shown box, type the Value data as 38b. Make sure you have selected Hexadecimal base here. Click OK. You may now close the Registry Editor and reboot to get fixed up.

    Thanks for all your help Dalchina. :)
