Things seem pretty good for my thinkpad since reinstalling windows.
I will say (and I've seen this before) that reinstalling windows always produces some minor differences that can be annoying. For instance, I don't use cortana and I disable that, yet when I've done that in the past the circle cortana turns into a magnifying glass icon. Not so this go around, I had to go into the registry to add a key. Conversely, the default weather app showed me Washington DC in the live tile on my original build, but its now working fine on the reinstall - ahh windows
I may be overly sensitive but my fans seem a tad more aggressive then before. To that end, I did install the Thermal solutions from the vantage app.
