My windows 10 120Gb SSD drive (C:) Has an installation folder c:/windows/installer which has become huge at 40.6 Gb. I have always understood these files to be undeleteable but not wanting to spend $ on a larger drive at this stage, I'm wondering if there is a safe way to regain some room. I have tried disk cleanup.

Use ccleaner / do a custom install. See if it removes the junk files etc

As well as Ccleaner, try running JRT.

Did you choose to cleanup 'system files' when you ran disk cleanup, and made sure to select anything substantial?

Its time to seriously consider a bigger HD.
Your lack of HD space will just become a never ending issue with one temp 'fix' after the other, freeing less and less space each time.

Some have suggested compressing that folder , havnt tried so dont know if its even do-able

IF it's the only drive I agree with 1101, 120G is just too small by itself.
If you also have a data drive however it's entirely possible to avoid these issues, my windows installation < 45G and I've had windows 10 running on a 32G tablet (don't do that - seriously)

Cleaning up old system files, installers, junk etc should help. You can also move any large data files elsewhere and consider moving the swap file (again if you have a second drive)
Do you have a windows.old directory at all? that can be removed via windows cleanup - CCleaner etc as suggested above.

Thanks all,
I had tried Ccleaner & JRT but no luck. However I did regain almost 8 Gb by turning off hyberfil.sys as I don't really need it but I'd still like to reduce the size of the install dir if I can safely.

Seems very strange that yours is 40GB. I have checked three here. Main comp 1.2GB/539 files with largest file 210MB, other two, around 650MB.

How is yours made so big. Large no. of files or several very large files?

PatchCleaner downloadable from Majorgeeks is supposed to fix these issues. You can choose to copy, rather than delete, for safety sake.
