browser history only goes back a few days

Which browser? Chrome itself keeps around 90 days, so a week means something is clearing it. Things to check: - Edge has Settings > Privacy, search, and services > Choose what to clear every time you close the browser. If browsing history is ticked there, it goes every time you close it - some browsers have their own history length setting, Vivaldi does - a cleaner app like CCleaner running on a schedule - if it's a work machine, a policy can do it too
