That's why one should switch to e.g. Tweaking Registry Backup.
I disagree. It is just another reason to not use 3rd party tools.
(Disclosure: I have helped the author of the TWEAKING programs (Tweaking.com) to get rid of A LOT OF bugs in those programs. That's why I am a bit "pushy" to promote those (Truly Excellent) programs).
That explains a lot.
A false sense of "I have all under control".
I am glad you admit that but IMO, it just illustrates my point further. Again this tool is not needed.
It is critical to
accept that Microsoft has every incentive to ensure Windows and our computers work optimally. Regardless what we may think and feel about some of the business and marketing decisions and policies at Microsoft, the developers are some of the world's best with PhDs and top computer scientists on staff with decades of experience and exabytes of empirical data to draw from and supercomputers for testing and simulations to ensure Windows runs at peak performance. If compressing the Registry was a needed task, Microsoft would put it in Windows - just as they have done with defragging, TRIM, Updates, and more. If compressing the Registry was that beneficial, then certainly other 3rd party apps would be available too and it would be something widely recommended. As seen
here it isn't. Note how old most of those articles are.
FTR, I am not saying all of Tweaking.com should be avoided. They do have some decent tools. I am just saying there is no need or benefit to compressing the Registry. If you
need the couple 100 megabytes of disk space you
might recover, then you have other issues and priorities you should be addressing that don't risk corrupting your operating system.
- Just being curious, please do the following: Install & run Tweaking's Registry Backup (on a win 10 or win 8 system) and see how large such a backup is before & after compressing the registry with e.g. Eusing's Registry Defrag
My advice is
DO NOT do this! If you, Willy, want to test such features on your own personal systems, that's just fine. But since any dinking with the Registry can result in an unbootable system (that might not be restorable via a Registry backup), please do not recommend others do it with their systems here. Thanks.
