I had a period where I _did_ reimage my machine every week. Keeping it running productively wasn't that bad - data was kept on a separate drive from the OS, and a script was used (as a post-reimage step) to reinstall all the apps I used and link all the data folders (and config files and profiles) into place. For me for Windows, that meant having a powershell script that used a combination of chocolatey (to install what was available via package manager in that way) and saved installers run from the command line in quiet mode (plus a bunch of link commands). The only real drain is that you need to remember when you install a new app that you need to add it to your script. Beyond that, simply keeping most non-application data on a drive that didn't get reimaged with the OS (and could store things that could be linked into the system drive) handled a lot.
