Usually never. I will list a few systems that are there in my home:
1. My personal laptop: I did an Windows 10 erase and install when I purchased it to get rid of the junk, and split the hard drive for a dual boot. I also installed Fedora initially, but a month later shifted to Debian 11, and have not touched that since. It has been 6 months.
2. My wife's laptop: It is very old - maybe 10 years. It used to run Windows till 2017. Then it fell into disuse due to a hard drive failure. I revived it with an SSD around the time Linux Mint 20 released, installed it, and it has never been erased since.
3. My father's and father-in-law's computers: These aren't in my home, but I manage them. They are also a few years old. They run Debian. Started with 9 I think. I updated them to 10 and then to 11. They work flawlessly too.
4. Phones: I erased my phone (Oneplus 6) only once after Oneplus stopped updates to install LineageOS. Others haven't been erased since they've been bought. All are over 3.5 years old.
