Reinstall Windows
Every time I reinstall Windows, it seems like I have to deal with reactivating everything all over again. This time, Office refused to accept my original activation. It was frustrating because I had important Excel spreadsheets I needed access to. After trying every fix I could find, I landed on kms pico. Their guide explained why this happens and how to reactivate Office using a KMS method. It worked instantly, saving me hours of stress. Now, I always bookmark activation guides before reinstalling anything.
