Who is a power user? According to Google:

Power user: a knowledgeable and sophisticated user of computers.

If you consider yourself a sophisticated computer user, then you should know the following Windows commands:

• Device Manager: devmgmt.msc
• Disk Management: diskmgmg.msc
• Certificates Current User: certmgr.msc
• Services: services.msc
• MMC Console: mmc
• Programs and Features: appwiz.cpl
• Network Connections: ncpa.cpl
• Sign out: logoff
• Shutdown: shutdown /s /t 0
• Restart: shutdown /r /t 0
• Paint: mspaint
• Calculator: calc
• About Windows: winver
• File Explorer: explorer
• Task Manager: taskmgr
• Remote Desktop Connection: mstsc

So, you won’t have to click through dozens of windows again to open the Network Connections dialog. Hit Win+R and type ncpa.cpl. And your done.

You want the old Programs and Features back, but Windows 10 is showing you the new UWP style feature-less unfinished App & features window? You don’t even find the Control panel anymore? Don’t worry. Run appwiz.cpl. Here you go. Thank me later.
