IMO, no, but I tell those that insist to use only Custom Clean and definitely don't use the Driver feature.

 

This used to be a useful app back in the day, but not so much anymore.

We do not suggest any Registry Cleaners/Optimizers like that option in CCleaner. This usually causes more problems than it solves.
The Temp file cleaner part in that app is still good, but Windows has the same built in apps with Storage Sense and Disk Cleanup that are just as good.

 

TBH I wouldn't and haven't bothered with it.

 

Full disclosure...I'm just remembering an issue I recently had with a corrupt Windows 10 user profile (that was unrecoverable). Had to setup a new one and lost a lot of system stuff (super annoying). And this was in/around the time I was running CCleaner scans.

I didn't consider it at the time, but possibly related?

 

The only program I allow to delete anything is Firefox, deleting its history cache and cookies when I tell it to.
Maybe there are some files that are sufficiently expendable to allow some program to delete them, but why take the risk? Machines and storage today are so fast and large, just ignore "optimization" and "speedup", unless you're running a huge, active database. Even finite element analyses on the ocean or hydrogen bombs need not concern themselves with idle files and storage fragmentation.
An exception to keeping unused files is that those files might be private. E.g., I prefer that my old tax returns reside on removable storage, so that I can take the machine to the shop without revealing my financial secrets, boring though they be.
And I do not allow God to touch my Windows Registry, whack-doodle though it be.

 

And I do not allow God to touch my Windows Registry

Quite right. The Registry is both very forgiving, and very unforgiving. It will happily co-exist with any number of orphans, and yet the removal of a single essential setting can cause an absolute catastrophy.

Never, ever, use "Registry Cleaners", "Registry Optimisers", or anything that tells you that it can automatically improve the performance of your machine, or automatically resolve Registry conflicts. In almost all cases running one of these tools will cause you more problems than they resolve.

If you are ever foolish (or desperate enough) to be tempted to use one of these tools, then please think it over, and reconsider your decision, but if not, please, please, backup your Registry before proceding.

 

I'd imagine then that this applies to Glary Utilities Registry Repair?

Let's just say it's not something I'd ever use myself, or recommend to others either.

With the Registry, the old adage of ... "if you don't know what you're doing, leave it alone" ... was never more appropriate.

I haven't used something like that in a very long time. I also haven reinstalled windows in a very long time. So from a longevity standpoint I would say you don't need it (I do make backups, which I have had to use here and there but that was either due to user error or hardware failure). I feel like we're talking win xp era where such actions still could be useful, but since win 10 things have been pretty darn stable. I'm on 10, I don't think I even reinstalled with my latest PC, just used a clone I think (I did that to a second pc on the same network but that did cause some issues, had to use "SIDCHG - SID changer utility" to fix it).
