Windows 10: After reinstallation W10 Disk clean-up indicates suddenly ''22,4 GB Previous Windows...

Only to check a back-up issue on my pc OS W10 vs 1809 x64 Microsoft helpdesk reinstalled W10 October 2018 update recently. The day after a full memory test had been completed successfully by the helpdesk as well.

However, today I noticed disk clean-up indicates that 22,4 GB of previous Windows installations can be cleaned.

This popped up just now so can I delete 22,4 GB safely? Kindly support.

'Clean' reinstall of W10

Hi all,

I am updating both of my W10 computers with SSD's and am wanting to 'reinstall' windows along the way, and with the very excellent and immediate phone support from MS, have just completed on both of these machines what they seem to call a 'Repair Reinstall'
of W10 that reinstalls the OS and retains all files programs and apps, which is great.

While upgrading both machines to an SSD primary drive, I am also retaining the original hard drive within the machine, which comes up as Drive J. I run these machines very cleanly, and personal files I need to retain are very minimal and easily saved to
a USB drive (or Drive J).

I would like to do a 'Clean' Reinstall of W10 that will wipe my machine 'clean' of virtually everything and reinstall the OS on a perfectly clean system, essentially bringing the unit back to as much of an 'as new' condition as possible; my concern is in
retaining and / or reinstalling my versions of MS Office and my Adobe programs.

I'm wondering if, before I begin the 'Clean' reinstall I were to disconnect my HDD (which is what my SSD was cloned from, so retains all my programs such as Office and my Adobe stuff), and then after having done a clean reinstall with my SSD, could I somehow
easily reinstall MS Office and my Adobe stuff from a freshly re-connected Drive J, or not?

I guess my question is this: With primary goal of having freshest, cleanest unit when done, what steps do I need to take to be able to reinstall my Office and Adobe programs after completing the clean reinstall of Windows 10?

Thanks for any assistance you can offer!

Reinstalling Windows (what drive)


It may be possible to troubleshoot and fix the boot problems and operating system/registry problems.
Sometimes access denied can be fixed.
Sometimes missing dll files can be fixed.

If you clean install, it can be performed in the shortest time however the files will be cleaned.
If you boot rescue the files can be backed up to another drive.

If you troubleshoot these are the initial steps.
The next steps will be based on the results displayed from these commands.

Perform the following steps:

1) Find a flash drive that you can format: ( > or = 8 GB)
2) Create a bootable Windows 10 iso (now Windows 10 build 1803)
Download Windows 10
3) Insert the bootable Windows 10 iso flash drive into any USB port
4) Power on the computer and click the applicable keyboard key or modify the BIOS boot order so that the USB external HD is on top

5) It may take 5 - 10 minutes for the iso to load while viewing the Microsoft Windows icon
6) Select the language, time, currency, and keyboard, or click next
7) Click troubleshoot
8) Click command prompt > Administrator: X:\Windows\System32.cmd.exe > X:\Sources>

Why 2.66 GB usable in 4 GB ram?

Thanks to everyone for their valuable suggestions. I guess the problem was with the OS.Because after increasing my ram from 4 gb to 8 gb still the usable memory was 2267 mb out of 8 gb, then I did a clean install of Windows 7.Now everything is fine and smooth, and usable memory is 7.9 gb out of 8 gb.
