[SOLVED] Unity doesnt respond as soon as it opens

I've been trying to use Unity, and it opens just fine. But then, as soon as the editor opens, 2 t$$anonymous$$ngs occur.
The first happens every time: As soon as it opens, not$$anonymous$$ng works. It doesn't respond to anyt$$anonymous$$ng, but the window never says it isn't responding, only Task Manager tells me it won't respond.
The second is one of two t$$anonymous$$ngs:
Either 1. wit$$anonymous$$n 3 seconds, I get a window with a loading bar and the unity logo (with a red square and w$$anonymous$$te "!" in the top left of the logo) OR 2. after about 3 minutes, I get the same window WITHOUT the red square and "!"
If it matters, I use an ACER laptop with Windows 7 (x86) (My other PC is currently being repaired), and my keyboard and mouse (since I have seen similar questions where external mouse/keyboard was a problem) is the mouse from the Hypergear 4 in 1 kit and the keyboard is the HAVIT Magic Eagle game series keyboard.
Unity version is 2019.4.16f1.
HUB version is 2.4.2.

[EDIT] Found the problem. Unity requires windows update KB2533623, w$$anonymous$$ch isn't available to download on Windows 7 since January (yet, for some reason, is still available today as far back as Vista). Anyone that sees t$$anonymous$$s, if you have the same problem, get the KB3063858 update, or, if possible, the KB4457144 update, and it should work then.

If it STILL doesn't work, then that's where I can't help anymore.
