What is the approximate installation size of a "clean" Windows 10 Upgrade, post install and cleanup?
I'm interested in the installation size of Windows 10 when it has been installed on an existing, clean, Windows 7 or Windows 8 installation. By "clean" I mean only a standard non-OEM OS and critical drivers, and updates.
For example:
- A computer is installed with a typical Windows 7 Ultimate x64 OS
- Critical updates are applied to the point that the Windows 10 Upgrade tool is installed
- Disk cleanup is executed to recover as much space as possible
- The upgrade tool is used to perform the OS upgrade
- After the upgrade is complete Disk Cleanup is again performed to recover space
How many GB would this occupy? Would there be a significant difference if upgrading from Windows 7 vs. Windows 8?
Microsoft says 20 GB for 64-bit OS.
I did a clean install, 12GB. Then added office, 16GB.
Then after a couple of days of windows update 50GB + 10GB in Recycle. 31 Gig in C:\Windows, 5 gig page and hibernate files.
And it grows substantially over time. 120Gig minimum.
This is for a clean install onto a new disk, keeping nothing. You are braver than I am to try an upgrade. My previous Win 7 install had suffered from windows rot (degeneration of the registry over the years) so needed blasting anyway.
(I use a Gargoyle router to throttle the windows update downloads from killing the internet for everyone.)
Today (2018-03-30) I did a clean* install of Windows 10 Pro with 23 GB.
* For me, this includes deleting all unnecessary pre-installed programs (for instance games, OneDrive, Weather, News, etc.), getting the newest updates, and running Window's Disk Clean-Up tool afterwards.
I did a clean install of Windows 10 Enterprise LTSC N from official iso file that had been published by microsoft itself
at first it was 16.1 GB and after installing updates and driver of my laptop its 28 GB now
Depending on the size of the drive, after Disk Cleanup, and the size and number of System Restore Points, you can expect a footprint of from around 22gig to as large as 35 gig. This is assuming the Documents folder and Pictures folder do not hold much data.
