My Lenovo Windows laptop was purchased around 2 years ago. Even then, I barely used it. It is essentially a glorified hard drive that I use to answer stupid emails.
This laptop contains data I have had for over 10 years. Family photos, bank statements, executable files that are for old games, emulated game file save files...I moved so many over. 10 years of files without checking where they're from. Let's fast forward to last month:
In my opinion, you have already made a mistake at this stage, namely, you decided to install the bitcoin wallet on a laptop that was used for everyday tasks (no matter how often you do it). This creates potential risks.
I would recommend separating the laptop for everyday tasks (surfing, movies, games, etc.) with the laptop for bitcoin. It is not necessary to have 2 laptops. It is enough to have a 2nd hard drive (HDD, not SSD for reliability reasons), on which the Linux distribution will be pre-installed (a priority over Windows) and install the bitcoin wallet on this OS. In the future, only under this OS interact with cryptocurrencies (purchase, sale, exchangers, etc.). Such HDDs can be connected via external USB ports (for the duration of operation). And if you add a hardware wallet to the bundle, it will be better from a security point of view.
You can perform all the other listed points on the Linux OS.
