That source came from dogecoin/peercoin price ticker extension and yeah if you have some free time and there's no important stuff, you can do a reinstall. Don't forget to take back of imp documents,downloaded files,desktop data (whatever comes in c drive).
no, of course i wont forget to backup. but i have a 4tb d drive so thats no problem, i have 2tb spare space left.
i'm an engineer myself, i just hate cleaning up desktops :p especially my own. I prefer linux servers to work on, u just need windows for tons of stuff impractical on linux! damn commercial crap.
the installation is straightforward, i have build an unattended install, its just every little piece of software that you need to install after the os is ready.
