Are you running 32-bit or 64-bit?
I occasionally need to know if my computer is 32-bit or 64-bit. The process is always a bit annoying and often involves a fair amount of Googling, so I’ve created a website that just tells you what you are using: 32-bit or 64-bit.
I’ve done a fair amount of testing and it seems to be pretty accurate. I think it will work for at least 95% of the people that use it.
Anyways, let me know if you run into a problem with it or if you find it useful!
