How to Uninstall Quick CPU Completely
Removing it is the standard Windows uninstall path, nothing custom — no separate uninstaller to hunt for, no leftover service to stop first. Here is exactly where to click, plus what a clean removal actually clears versus what sticks around for a reinstall.
Removing it, start to finish
- 1
Open Windows Settings
Settings → Apps → Installed apps (Windows 11) or Settings → Apps → Apps & features (Windows 10).
- 2
Find Quick CPU x64 in the list
Search "Quick CPU" if the list is long — it registers under that exact name, the same one shown in its own About dialog.
- 3
Click Uninstall and confirm
Windows runs the same installer package in reverse. Confirm the UAC prompt — removing a machine-wide app needs admin rights, just like installing it did.
- 4
Restart if you plan to reinstall
Not required to finish the removal, but worth doing before a fresh install if you're troubleshooting rather than just uninstalling for good.
That's the whole process — there's no separate uninstall wizard bundled with the app, no "are you sure you want to leave" survey, and nothing that tries to talk you out of it. Windows' own uninstaller handles the file removal, the Start Menu shortcut, and the registry entry that listed it as an installed program in the first place.
What gets removed, and what doesn't
A standard uninstall removes the program files, the Start Menu shortcut and the registry entry that made it show up in the installed-apps list in the first place. Any Windows power plan settings you changed while it was running — core parking, turbo behaviour, the active power plan — stay exactly as you left them. Uninstalling Quick CPU doesn't put Windows back to factory defaults; it just stops the app itself from being able to change those settings anymore.
What can survive a standard uninstall are your own custom profiles and a few app preferences, stored per-user rather than alongside the program files. That's usually convenient — reinstall later and your saved profiles are still there — but it's worth knowing if your goal is a genuinely clean slate rather than a quick removal, since it means "uninstalled" and "no trace left" aren't quite the same thing here. Deleting the leftover app-data folder manually after the standard uninstall is the only way to close that gap completely.
Confirm what you're removing
If more than one version has ever been on this machine, the About dialog (Help → About) is the fastest way to confirm exactly which build Windows is about to uninstall before you commit — useful if you're mid-troubleshooting and about to reinstall a specific release.
Common uninstall problems
A clean removal usually goes without a hitch, but these three cover almost everything that trips people up.
- It's not in the Installed apps list.Search by "Quick" rather than scrolling — Windows sorts alphabetically but sometimes groups differently than expected. If it genuinely is not there, it may have been run portably rather than installed; check for a folder under Program Files instead.
- Uninstall fails partway through.Make sure Quick CPU itself is closed first, including any instance minimised to the system tray — an app can't remove files it still has open.
- Settings come back after reinstalling.Custom profiles and some preferences are stored per-user rather than removed by a standard uninstall. If you want a genuinely clean slate, check the app data folder under your user profile before reinstalling.
Uninstalling Quick CPU: quick answers
Does uninstalling Quick CPU require administrator rights?
Yes. Removing a machine-wide app needs admin rights, just like installing it did — confirm the UAC prompt when Windows' own uninstaller asks for it.
Will uninstalling reset my Windows power plan settings?
No. Any power plan settings you changed while it was running — core parking, turbo behaviour, the active power plan — stay exactly as you left them. Uninstalling only stops the app from being able to change those settings anymore.
Do I need to restart my PC after uninstalling?
No, not to finish the removal. It's only worth doing first if you're about to reinstall a specific build while troubleshooting, rather than uninstalling for good.
Will my saved profiles be deleted when I uninstall?
Not by a standard uninstall — custom profiles and a few preferences are stored per-user rather than alongside the program files, so reinstalling later brings them back. Delete the app-data folder manually first if you want a genuinely clean slate instead.
