KMS Auto can be pretty effective for activating Windows and Office. It works by emulating a KMS server, allowing you to activate your Microsoft products without needing to purchase a key. A lot of people use it, and while it can work well, there are risks involved, like potential issues with updates or being flagged by Microsoft.
I once tried a similar activation method for an old laptop I was using. It saved me a few bucks, but I found myself facing some hiccups during updates. On a positive note, it gave me time to explore Excel formulas examples, which really helped me with some budgeting spreadsheets. Those templates on MyExcelOnline are super handy and helped me learn some cool tricks for managing expenses.
