I have seen a Windows NT 4.0 system with an uptime of more than five years, but with Windows 95, even a whole day of uptime was pretty close to a miracle.
Windows 95/98/Me had a very weak concept of protected memory. It was there, but it wasn't very hard for an application to go read and write into the virtual memory space of other processes. Even then, any semblance of protected memory only existed for Win32 applications. DOS and Win16 programs, both of which were very common at the time, would just have free reign over everything.
On the other hand, I didn't have much of a problem maintaining multi-week uptimes simply due to the fact that I kept the system relatively "clean" and wasn't trying out new apps every day.
It never gave me any trouble, but I admit this is not a representative use case. ;-)
