thanks Jim !
something like this ?
I think I started with windows 98 . still got the disk
Pretty close! LOL!
I learned Windows 95 by breaking it so many times and having to reload it, that I started digging into it and figuring out what made it tick. I had already learned a lot about DOS, so I had a starting point, as Win95 was built on DOS 6.22. I got a copy of Win98 Beta 3 when it became available, and started to really learn how it worked. I learned to customize the OS, tweak it for better performance, etc. When Win 98 SR2 came out, it had a memory leak that caused it to lock up if you let it run for a few days. I figured out how to fix it, and asked a tech at Microsoft if they had figured out how to fix the leak, He said they hadn't come up with a solution, so I told him what I had done. A month later, when the company I was working for got a new shipment of SR2 CDs from Microsoft, my fix was already incorporated. I didn't get any official credit for it, but I'm the guy who fixed the memory leak in Win 98 SR2.
I haven't had the time to dig into XP, Vista (yuck!), or Win 7 as much as I did Win98. Since they're built on NT, the underlying architecture is completely different. My work now doesn't have me fiddling with things too much, just imaging systems, and configuring them for the closed network they attach to. The retail software interface is already installed on the image, which runs on top of Win XP SP 2.
My next endeavor is to get the new tablet I just got set up and start playing with it. It's an HP Touchpad (got it really cheap) running WebOS. Supposedly there will be an Android version worked up for the Touchpad sometime, at which point I will probably switch to that, since I have an Android phone.
I still think back with great memories of the 4 years I worked at Skyline Microsystems....that's where I got 99% of the knowledge I use now in my work.
