My sister got my windows computer after I got my mbp. I clean installed windows 10 for her and after a year, she was experiencing so many problems. Opening the start menu took literally 4-5 seconds after you pressed it, blue screened practically twice a day, etc. I suspect its more her fault because it was running completely fine for me for 3 years. So I decided to install the original software that came with it, windows 7. It took me four whole days (I didnt have work those days). What I am about to tell you literally surpasses any sense.
On the first day, I couldnt download windows 7 from microsoft because it told me that I had a Lenovo windows 7 key and I had to download from lenovo itself. Lenovo didnt have windows 7 at all. Therefore, I had to download windows 7 off of a torrent site (rip KAT). Download takes 3 hours. Then I had to burn the iso to a flash drive which took 30 min. I plug it in, and guess what? The entire os is in German and there is no option to change to English. f**k me.
So I searched for a new windows 7 download. Finally I find the right download. However, this already took me an entire day and I had to wait till tomorrow. I wake up tomorrow thinking it would be smooth sailing from here. Little did I know, it was just the beginning.
On the second day, I install windows 7 on her lenovo desktop using the key from the back (turns out my lenovo key does work with any windows 7 download, f**k you microsoft). This takes a good hour to install. After it is done, I install chrome and start installing back applications. Standard stuff. I go into the control panel and check for updates because I know there is going to be a lot. 10 min go by, nothing. 30 min go by, still nothing: says its still checking for updates. 2 hours go by nothing. I leave it over night checking for updates: STILL NOTHING.
Turns out this is a common problem installing windows 7 ever since windows 10 has come out. On the third day, I had to update "windows update" manually. S**t how is this "user-friendly"? If my dad or basically 70% of the population were faced with this problem, they would have never noticed this and would have been running windows 7 with no updates forever. Finally installed the update and after a couple reboots I was presented with all the updates. I had around 200-300 updates to go; around 2.5gb. Thats amost the same size as the original windows 7 installation iso. Now I was really starting to get pissed off. I click download and install all updates and leave it overnight.
Wake up on the fourth day, turns out the windows update stalled overnight and didnt installing any updates. I was about to just leave her computer the way it was and never touch it again. Instead I spent the entire day, installing every single update one-by-one. After this whole ordeal, I will never touch a windows computer ever again.
