I've been having a few issues recently with some programs with reside within the system32 folder, as said in the title paint, notepad and calculator. Explorer is having a different issue so I'll discuss it later.
The 3 programs listed are constantly crashing. Notepad and calculator are having significantly bigger issues than paint right now, however they all have the same issue.
Whenever I open one of these programs, it'll either be a few letter (numbers for calculator) and it'll crash, with the generic error message "xxxx has stopped working, Windows is searching for a solution". This problem happens consistently.
Explorer on the other hand, is behaving oddly. Every couple days (sometimes multiple times in a day) my toolbar will not pop itself back up (I have it set to autohide). While the trace of the hidden toolbar is visible, no moving of the mouse (even when on the desktop to avoid 'always on top' programs taking priority) on the toolbar will bring it back up. This usually results in just killing explorer.exe and re-running it.
