My C:\Windows\Installer\Razer? is over 13GB. I’ve read from others that it can be unsafe to delete this. Is there a good way to reclaim this space? Is it actually safe to delete?

Hi Michell!
On my machine, RazerInstaller.exe exists in the App folder itself. Otherwise, there were 397 exe files there. Removing those took the C:\windows\installer\razer folder size from 13.3GB to 180mb. If I experience any issues with updating the Razer software, I’ll update this thread. Thanks!

My folder is at 5.6 GB. That’s insane. Why is this happening? Can you please release a fix so that Razer doesn’t take over my whole storage??
In the meantime I’ll try the steps above, but the fact that we would have to manually check it and manually delete the bloatware is really unprofessional.

They just seem to be update-files that Razer's update-method seems to refuse to clean up after itself. - I've also had this issue, having built up tens of Gigs of Razer-files over the span of a few years on the same Windows-installation, and wondering where my drive-space went. - I had to find out with one of those drive-space-analyzers, because these are basically "hidden" files. Or at least they're not in a location you tend to go and see, and they're also not put there with the user's permission.
And, no, removing those files (with the longer names) generally shouldn't cause any issues, because they're basically just update-files that Razer's updater runs, but doesn't remove when there are new ones. - You could leave the newest ones to be safe, as perhaps they might be used or something. But the user shouldn't be expected to manage these files. Razer should program it to clean up after itself if those files are old and won't be used anymore.
This is really bad practice and shouldn't happen. I can't believe this still happens, as I complained about it at least half a year ago and I know it had been noticed back then.
