Does anyone know why Windows 10 installation grows so large? I installed Windows 10 (Clean install) on my desktop about 6 months ago and I always disable restore points after install. Only thing I have installed is Winrar, Office 2015 (Only Word, about 500mb), AMD drivers and Avast. I remember it was about 20GB after install and now 6 months later it's again over 50GB. Same thing with laptop. I have OS X Yosemite on another laptop and if I remember correctly it was about 10GB after install and has been like that ever since.

 

I have done all the disk cleanup steps and Windows has cleaned everything it can, there are no temporary install files or anything left. For example C:\Windows is 22GB.

How much RAM do ya got (didn't see it in your specs) ... you know your pagefile is going to match that.  So if you have 16GB RAM...you have a 16GB pagefile.  hiberifl.sys will also be big if you have hibernation enabled.  You can turn off hibernation by admin CMD prompt and entering ...  powercfg -H off

 

You could also have a lot of restore points (I know you said you disabled it) ... but to double check ... you can run the following from elevated CMD prompt

 

Vssadmin List ShadowStorage

 

Which would give you something like this....

 

Shadow Copy Storage association
   For volume: (C:)\\?\Volume{b91283c4-7b61-11e4-88e9-806e6f6e6963}\
   Shadow Copy Storage volume: (C:)\\?\Volume{b91283c4-7b61-11e4-88e9-806e6f6e6963}\
   Used Shadow Copy Storage space: 1.21 GB (1%)
   Allocated Shadow Copy Storage space: 1.67 GB (1%)
   Maximum Shadow Copy Storage space: 5.93 GB (5%)

 

How big is the WinSXS folder within the Windows directory?  If it is huge (mind you the size shown is deceptive), you can read the following....

https://msdn.microsoft.com/en-us/windows/hardware/commercialize/manufacture/desktop/clean-up-the-winsxs-folder

 

Lastly, when you are doing Disk Cleanup ... you are also selecting "Clean up system files" .. right?  Also, under Disk Cleanup you can "clean up" the system restore and shadow copies under "more options".

 

As @Ilysmentioned ... you can use a tool like Folder Size to find out which folders are using the most space ... and investigate from there.  

 

Anyway...hard to really tell you why you installation is taking up so much space without actually being at your computer.

Your WinSxS folder is probably ballooning due to cached install files, libraries/dlls and what not. You can also take a look at your software distribution folder for updates. Both these are common reasons as to why your Windows install grows. I wouldn't mess with WinSxS, at least unless you know your way around with DISM, and even then it can be quirky, but you can probably clean up your software distribution folder. Another area that grows frequently is your AppData folder in your profile. Your internet cache and program customizations all take up space.

    • Free Software Foundation Europe pushes EU to force Google to allow AI uninstalls on Android

      Free Software Foundation Europe pushes EU to force Google to allow AI uninstalls on Android by Paul Hill Credit: Pexels Users should be able to fully uninstall AI-based features from Android devices and be able to access interoperability functions, free from Google’s verification requirements, the European Commission has heard as part of an Android interoperability consultation under the Digital Markets Act. These measures were proposed by the Free Software Foundation Europe (FSFE) last week when it submitted its documentation. The FSFE noted that Google had started silently installing AI models without telling users. It noted that the EU’s DMA requires companies like Google to allow users to uninstall pre-loaded software from their devices, but in the case of the AI models Google is installing, they reinstall if you delete them, contravening the DMA. To get Google back under control, the FSFE has told the European Commission that there needs to be improvements within the Android Open Source Project (AOSP). First, it said that users should be able to fully remove pre-loaded AI components from their devices, with companies being prohibited from silently reinstalling or reactivating them. Second, access to Android interoperability features should not be contingent on registration, authorization, or contractual relationships with Google. This pertains to Google’s attempt to force developers to register with Google, even to publish apps to alternative app stores like F-Droid. Discussing its submission, Lucas Lasota, FSFE Legal Programme Manager, said: Google is planning to roll out its Android Developer Certification in September 2026. This will force every Android app developer to register with Google before their software can be installed on certified Android devices, but it should affect those who have removed Google Apps from their device. The program is controversial because it entails the signing of contracts and payment of account fees to Google, as well as the handing over of the identities of developers. It said: The FSFE said that if the Commission’s draft measures remain unchanged, then Google will be allowed to make developers verify their identity. The FSFE believes that asking developers to register is contrary to the text and spirit of the law. In summary, the FSFE has told the Commission that no developer should need a Google account, a Play Store presence, or any agreement with Google to access Android’s interoperability features.
