Four years ago, I set up my new PC and made a basic image with Macrium. No security software except Microsoft Defender. Every 2-3 months, I update or upgrade that image. Last week I upgraded to Windows 21H1 and updated Macrium. I keep 5 basic images. I can use F-Secure for many months, but this software is not a part of my basic images. Only Microsoft Defender. And Configure Defender.
This week, I use Microsoft Defender with Configure Defender and Voodooshield 6.50. In the last 4 years, I had to go back twice 6 months earlier to get rid of a bug but, most of the time, my PC stays very stable.
