I updated my drivers of a Lenovo P520 Intel Xeon W2025, win 11, with the driver updater of CCleaner. The computer rebooted and then it could not get started, no matter what I deactivated in the UEFI . The system was totally broken, and I had to reset the system, losing all my apps including the paid ones like Office 365 and CCleaner licence.
what a Cluster**** .
how can this happen and why does CCleaner changes drivers with incompatible ones. Dangerous program
My question : How can I know what driver I can update and which ones I should not even when CCleaner recommends it?? Who knows the answer ?
I updated automatically the drivers on my Lenovo P520 Intel Xeon W2025, Win 11 desktop.
Then I rebooted, and then the computer did not reboot. none of the recoveries, changing of UEFI etc repaired the problem. I had to reset completely, losing all apps including paid ones! ( I though when everything is updated, then I make my system back-up. I should have back upped, before trusting CCleaner to do the driver updates.
Beside making a total system update, what else can I do to select which of the recommendations of CCleaner is compatible with my computer and what is not !! CCleaner does not know is proven by now.
I honestly wouldn’t use a driver updater ccleaner or other.
Two cases for driver updater
Self-built computer. Though if you know enough to self-build you know your hardware and can get the updated drivers with a little legwork (go to offical sites for all pieces).
EOL computer OS. Windows eight doesn’t get updates (and I’d assume driver updates) through Windows update. But still do at your own risk.
My Logic: while a piece of hardware may use a certain driver and that driver (the software) may have a newer version that does not mean that the revision of the hardware you have will work with it. For the most part windows update takes that into consideration while driver updaters (including ccleaner’s) don’t tend to.
Of Note: I disagreed with this tool’s inclusion in ccleaner but i’m but one voice amongst many who are (for what reason IDK) wary of using windows to keep their drivers updated.
Threads merged please only open one thread per issue 
I apologize. I did not know about hiding and unhiding of a post, so I thought the post was lost and i had to redo it. Sorry
no worries, one of yours was flagged by bots as “typed too fast” so the fault was ours 
Any and all Driver Updaters can be dangerous.
I never update a driver if the one I already have is working OK.
Updating drivers when not needed can cause problems.
Drivers most usually get updated to suit new hardware.
You do not have that new hardware, you have older hardware and the new driver version may not suit it.
The Driver Updater just tells you that there is a ‘newer’ version than the one that you currently have, but it doesn’t, it can’t, tell you if the ‘newer’ driver is suitable for your hardware or not.
(Well it could do - if it was a bigger more sophisticated app it could do a lot more checking - but that’s harder to do. and more costly).
So each time that you use a Driver Updater, any Driver Updater, you run the risk of updating to an unsuitable driver and causing problems.
As you have already found out to your cost.
So did I, so did all the mods here, we knew that in the end we would have to deal with the fallout when people started to break their machines by updating drivers to ‘newer’ but incompatible-with-their-computer ones.
Dear Nergal and Nukecad. Thanks for the clear answers. If the mods can not convince their managers and marketing colleagues to hide the driver-updater, then at least CCleaner should add a warning text. And/or a possibility to exclude the driver from the updater, in combination with a recommendation: use the updater only to inform you to search for update-installers from the hardware-producer. If that install-program of the hardware producer does not use the newer version, than it is incompatible to your machine, exclude it from the updater of CCleaner.
I consider the question as closed. All the best Mayke
This is why I use disk imaging software - any problems with driver updates or anything I can roll back using the image.
