Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Disk bloat in Windows 10 Fall Creators Update

Is it my imagination, or does the Windows 10 Fall Creators Update consume an additional 20-30GB of disk space over the previous Creators Update release? Unfortunately, I didn't log my disk usage before the upgrade, but now my C: drive has 56GB of stuff, and I know it wasn't anywhere near that full before. I've run "Disk Cleanup -> Clean up system files" and selected everything on the list, including remove previous version of Windows. I also emptied my Recycle Bin, my Temp folder, \Windows\Temp folder, and \Windows\SoftwareDistribution\Download folder. Finally, I ran Wise Disk Cleaner to delete assorted application garbage.

Has anyone else noticed the bloat in Fall Creators Update?

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
