1. Remote Desktop without password. You will be able to login, but kick out randomly.

2. Smart switching when more than one IME installed. Example, I have English, Chinese and Japanese installed. But mostly switching between Chinese, and English (using Shift+Alt). In Windows 7, it is smart enough to switch between the two most recently used IME, but in Windows 10, it cycle through the list.

3. Remember most frequently used characters in IME, and move it to the default selection. Not all IME are working (compared to Win 7), especially the MS Changjie.

4. IME Wildcard character in Changjie. Use 'Z' key as wildcard was missing after win7.

5. Disable address bar search in EDGE all together. When I type www.google.com, I mean I wish to goto google, not asking BING (or any other search engine) to search for google.

6. Ability to right click and select Save As location in Edge when downloading files.

7. Ability to scroll back multiple pages in EDGE. There are many web sites doesn't allow us to scroll back, but we will be able to do the trick if we scroll back multiple pages. Instead of starting all over again.
8. USB drive / Thumb Drive (some random brand, random model) will goes into sleep mode after idle and unable to recover without a restart.

9. Stop the annoying tiles from updating themselves and waste my bandwidth.

10. ... Will add more later ...
