Sorry, I was thinking you were needing to choose between installing W10 or W11. You already have W11 installed... so you can just do an update/upgrade. Windows Update will likely ask you if you want to do that and you just click yes. (Might be automatic update also... MSFT presumes you intend...
You will need MSFT's "Media Creation Tool". You can look that up. All you'll need to get started is a flash drive of at least 16GB (the media creation tool will erase everything on the drive and reformat before installing files for the fresh OS install). It doesn't take very long. I don't...
IMV, it's that $5T Covid stimmy + another $4T Dem deficit spending.. $9T of EXCESS money sloshing around in the system. It keeps changing hands for new buyers to buy again and again. Fed never drained excess reserves, so we're likely locked into high inflation until Fed does something about...

As to the notion of a "false upside breakout", we all just have to cope with it. Suggest playing the breakout level to be a pivot... so that however it plays out, you can't get hurt much.
As for rate cuts... IMV, rates were never high enough. Neither was excess money in the system from covid...
If SP breaks above, holds, and follows through, it's a buy/long indication. If this level fails, it's a sell/short indication. (Not a specific "price to the tic", but rather a small zone... you'll likely need to use some judgement on this play.... but up to this second, this high has backed...
Slippage is still a concern. I define slippage as the price differential between the time when I "decide to make a play" and when it gets executed... even with today's market in the SPY or other, you still have to "construct" an order on your computer and then submit it to the market. How much...
Electronic markets evolved to replace "open pit outcry markets" like in the old days. The primary benefit was reducing the overall transaction cost of trading.. primarily slippage.
