  > you specifically said No, you communicated before with somebody else. > still leaves up to 5GB of redundant garbage No, if you read that example, there is less than 1 GB which is stale (the diff between the first and the third number): >> Windows Explorer Reported Size of Component Store : 4.98 GB >> Actual Size of Component Store : 4.88 GB >> Shared with Windows : 4.38 GB As I've said, you intentionally didn't quote your machine's third line but I'm sure it's not a 5 GB difference. Moreover, that difference can be purged if necessary. Which you can also do on your machine with just a single command, per link on the same page: https://technet.microsoft.com/en-us/library/dn251565.aspx https://technet.microsoft.com/en-us/library/dn251565.aspx There is a trade-off, the probable case why nobody does it unless really necessary: "All existing service packs and updates cannot be uninstalled after this command is completed"
