The control software itself probably served its purpose. In recent years, she has my tax return always halfway hammer out, though not always intuitive (even in the Child Tax Credit). Therefore really 4 stars. Two star deduction is available for a system service that runs continuously in the background after you install the software. Normal software you can start and stop again. Most will be searched automatically at startup for updates. The tax-saving explanation, however, automatically installs a system service that runs continuously after installing in the background and must be uninstalled separately (see "Update Manager AAV", ie alphabetically in the list also nice separate from the tax savings declaration). This is a reputable software simply not worthy: Once installed this system service runs continuously in the background and consumes resources (albeit few) - even after uninstalling the tax-saving explanation. I do not know what's driving the whole time. The part just did not.
