Chrome 37 UI got larger and became blurry on 125% DPI  http://superuser.com/questions/803710/chrome-37-ui-got-larger-and-became-blurry-on-125-dpi

Hiding the tool bar / showing page thumbnails by default
Go to the install directory, i.e." C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroApp\ENU". Create a new subfolder (I used "Disabled"). Move 3 files from the "ENU" folder into the new "Disabled" folder: AppCenter_R.aapp & Home.aapp & Viewer.aapp. Open a PDF and no more Tool Pane!  I originally moved just the "Viewer" file but if you clicked on "Home" or "Tools" on the toolbar you couldn't go back to the "Document." Moving all 3 files takes care of that issue. Like a lot of people I don't and won't ever use any of the tools. I just want a reader. Let me know if this works for you.

MBRFix工具修复MBR很方便，打开cmd命令窗口，进入mbrfix工具所在的目录（比如c：/），然后输入命令 mbrfix /drive 0 fixmbr （注意drive 0根据您安装grub之前windows操作系统的启动分区位置而定的），再确认一下就行了。重启以后就ok了，直接可以进入Windows了。使用”高级启动“-》”启动修复“ -》命令行-》运行 Bootrec.exe
But sometimes I can't rebuildbcd(because it complain it can't find database or storage. same issue when run "bcdedit"). To fix it, run "robocopy" & "bcdedit /store" as this article.
