    Reduce Windows size in HDD

    Hi ,
    sorry for my poor English.

    Windows is tkaing around 20GB on my PC, and my HDD is only 32GB has 8GB free.

    What and how can I reduce its size to a minimum size?

    Windows 10 no longer automatically reduces the size of a photo to attach in an email. WHY

    The only way to reduce the size of a photo is to reduce the number of pixels in the image, which reduces the quality of the image. But when an image is visually smaller, you don't notice the degradation. Take a reduced size image and compare it to the original
    when both are at the same size visually, e.g. both are 4x6 or 5x7 and you'll notice the difference.

    Therefore, if you're reducing a photo to include it in an email or a Word document, for example, make sure to reduce a
    copy of the original photo. If you reduce the original, it's reduced forever.

    Someone had to tell the software how much in size to reduce the picture (e.g., 75%, 50%.) Windows can't make that decision on its own. If you don't recall telling the software what size to use, it was probably using a default value programmed by the developer.

    Going forward, attaching a photo to an email just to get it reduced in size is a convoluted method, no? No need for that when there are so many good (and free) photo resizers available for download. Just be sure that when you install a photo resizer, that's
    the only thing you're getting, i.e., no viruses or add-on programs you didn't ask for.

    Reduce Windows size in HDD

    Bear in mind that Windows creates a copy of the Windows folder when either
    - there's a major upgrade build
    - you do an in-place upgrade install repair

    That is, you need 20Gb free for that.

    That begs the question as to where you put your personal data and installed programs.

    It is possible to shrink windows significantly- hopefully someone who's familiar with that may help- I've only read about it in passing.

    Is that a SSD and do you have another disk in your laptop?

    Thank you .
    Sorry for my mistake, it is a eMMC storage not a "real" HDD.
    I can not upgrade, neither use more than 32GB SD-CARD.

    @NaviLCDR - Thank you for the info. Disk Cleanup I use it since ages regulary.
    Good point that with "Compression", I will try it.

    Reduce Windows size in HDD

    Windows 10 uses a compressed OS on tablets. By default it is normally on.

    From an admin command prompt, type

    Compact.exe /CompactOS:query

    Windows 10 Feature Focus: CompactOS

    When you run disk cleanup, select to delete old system files, and tick all boxes in popup list.

    Assuming you can put an sd card in, you can change your user directories, and apps to use sd card (settings, sytem, storage).

    Hi cereberus,
    Thank you.
    I cheked it with the CompactOS and is enabled.
    I did clean the Drice C: and there not that much to win.
    I there a way to uninstall Windows Native App´s. This is a very small laptop and space is required and I do not need / use a lot of that App´s
    Adalwar, May 17, 2016
  10. But do you use the full one or the standard one?
    cleanmgr /sageset:65535 & cleanmgr /sagerun:65535

    To decresse size of WinSxS's folder:
    Dism /Online /Cleanup-Image /StartComponentCleanup /ResetBase

    To remove all system restore points (disable system restore completely, if you do not use it)
    vssadmin delete shadows /for=c: /all /quiet

    Additionally, you can use CCleaner + WiseCare, to free a few more hundreds MBs, like those 3 settings:

    Make sure to move your library folder location to a different storage drive if you have any. Don't save your data on the same drive as the OS.
    I have an ASUS T-100 10" Windows tablet and as much as possible, I use portable apps instead of full programs that requires installation.

    I have a Dell Venue 8 8" tablet that came with Win8.1 and now has Win10. It came with a 32GB SSD/Solid State Drive and used about 19GB of the space so I added a 64-bit MicroSDXC card for storage, probably will get a 128GB when prices drop a bit more. To save space I installed LibreOffice instead of Microsoft Office, not only free but a smaller footprint.

    Reduce Windows size in HDD

    You should also see if there are duplicate drivers you can eliminate from your DriverStore folder. I recommend the MS Codeplex project (free, open source software) tool named RAPR.exe aka DriverStore Explorer. If you've updated drivers and your current config is stable, you can often free up 2-5 GB of disk space by flushing out obsolete, no-longer-used drivers. I've written about this repeatedly for publication. Here's a link to a story I wrote last year for entitled "How to reduce unnecessary drivers in Windows 10." HTH and good luck with your pruning efforts!
