Windows NTFS Compression and Native Boot VHD/ VHDX? Issues or Conflicts? 
I am currently cleaning out my Windows 7 x64 Ultimate SP1 for a 2 step upgrade > Win 8 > Win 8.1 and then will convert it to VHD. 
I have this \Windows\Installer folder that is taking a lot of space and seems to be unused mostly. 
Eventually, I wish to clean it out/ delete it or major stuff inside it. 
But, till then I was considering "compressing" option it as suggested here instead of delete/ remap right now. 
If I do this right now (during Win 7 > 8 > 8.1) I am wondering this will cause any issues creatingin or running the VHD? 
I googled around for VHD and NTFS compression and did not find anything good or bad either way (with exception that Windows XP and VHD had some issues)

Be forwarned that I haven't used any of these and therefore do *not* endorse their usage. It's up tp you.



There also appears to be a Win7 Update that will CleanUp unused stuff. I haven't fully updated any Win7 OS as-of-yet, so...

Also, backup, backup, backup in case something flubs you up.


As for your initial Q about "compressing" I'm not really sure what that will do for you since mostly that Folder contains MSI/MSP files anyway. You *may* gain somewhat but I'm really unsure how much. I'd recommended downloading 7-Zip and (using it) create a ".ZIP" file (not a ".7z" file) of the folder to see if there's any gain to be had (ZIP file size vs Folder size). If not, then it would be pointless anyway. See comments here (even one about Installer folder) -



After all, a Compressed Folder is just a ".ZIP" file anyway. Whether the OS would "recognize" it for any future Installs and use that instead of the "actual" (physical) Folder I have no clue.




edit - Most references are about an SSD. Can I assume that's your case?
