Boeing77W :
So I tried to set a custom Windows skin using WindowBlinds 10 but the program crashed on itself while setting the theme, leaving me with a broken UI. I can start up Windows and log in but the desktop is just pitch black with my cursor. Pressing Ctrl + Alt + Del returns an error as well. Is there any way to fix this, or do I have to format C: and reinstall Windows?
FYI I am running Windows 10 Anniversary on an SSD.
Hmm sounds like your Windowblinds 10 might not have been up to date. Windows is probably not corrupt. At your login screen hold down shift and in the bottom righthand corner tell the computer to restart. This will allow you to access the recovery tools through the menu's you should be able to get to safemode.
(Select Troubleshoot -> Advanced Options -> Startup Settings -> restart -> hit F4, F5, F6, 4, 5, or 6 on your keyboard when given the option for what to boot to. When you get logged in with safemode uninstall Windowblinds and reset. You should get your desktop back from there you can download and install the latest version from stardock's website.
