Yesterday Microsoft released the new version of the TFS Power tools.
See what Brian Harry blogged about it here.
First of all, the installation made simpler since you don’t have to
uninstall previous version, just install new version over the old one.
Only one thing – the installation prompts that Windows Explorer
process should be close.

If you press Ignore reboot will be required.
Anyway, if you kill the mentioned processes through Task manager,
no need to reboot.
Here some of the new Features in this release:

- Rollback on Changeset from history

- Rollback from Source Control Explorer

Grab it from here.
Take a look also at the updated Build Extensions.
Enjoy !
