Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →gamebooster.exe is not a unique Windows component. It is a filename used by more than one program, including a documented 360 Game Booster component associated with QIHU 360 SOFTWARE CO. LIMITED. Whether a particular copy is safe depends on its complete path, digital signature, parent application, origin, and current security scan—not on the filename alone.
Use the checks and repair sequence below before launching, deleting, or allowing the file. They apply to Windows 11, 10, 8.1, and 7, although menu names can differ slightly by edition.

What gamebooster.exe is—and why the name is ambiguous
Windows does not reserve gamebooster.exe for one operating-system service. Any software publisher can choose that filename. A documented sample belongs to 360 Game Booster, published by QIHU 360 SOFTWARE CO. LIMITED, and normally installed under C:Program Files (x86)360Total Security. FreeFixer’s analysis of that particular sample reported a valid digital signature from the publisher and no detections from the antivirus scanners listed on its page at the time of analysis.
Recommended Free Tools
Those observations identify one sample; they do not certify every file called gamebooster.exe. A malicious program, an unwanted bundle, or an unrelated game utility can use exactly the same name. Treat the filename as a clue that needs verification.

The full path is especially informative. A copy inside the recognized publisher folder and installed with a program you intentionally chose is less suspicious than a copy in %Temp%, a random folder under your user profile, a startup directory, or an unknown download location. Location is evidence, not proof: malware can imitate a legitimate directory, and legitimate software can be installed elsewhere.
Is gamebooster.exe safe?
There is no universal yes-or-no answer. Establish the identity of your copy using all of these attributes:
| Check | Lower-risk result | Higher-risk result |
|---|---|---|
| Publisher and signature | Properties shows a valid signature from the publisher that made the parent application; the certificate chain is valid. | No signature, an invalid signature, an unknown signer, or a signer unrelated to the software you installed. |
| Full path | The expected installation directory for a program you recognize, such as the documented 360 Game Booster location. | A temporary folder, browser-download folder, random user-profile directory, or an unexpected startup location. |
| Installation source | You downloaded the parent application from its verified publisher or the Microsoft Store. | The file arrived in a bundled installer, an unsolicited download, a crack, or a pop-up. |
| Parent application | Installed software lists a game utility you recognize and can remove normally. | No corresponding application, or an installer that added other programs without clear consent. |
| Security scan | Microsoft Defender is updated and reports no threat. | Defender detects the file, or the file is excluded from scanning without a documented reason. |
| Startup behavior | It starts only with the game utility you chose. | It creates unexplained startup entries, repeatedly relaunches, or changes browser or Windows settings. |
| Removal | The parent program uninstalls from Windows Settings. | Removal is blocked, the program reinstalls itself, or deceptive warnings pressure you to keep it. |
Microsoft describes unwanted software as software that can be difficult to uninstall, change browser settings, display excessive health messages, or install other software without clear consent. A suspicious result in one row does not prove malware, but several together justify isolating the file and investigating before you run it.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Verify the file without launching it
1. Record the exact path and parent program
- When an error names
gamebooster.exe, note the complete path shown in the dialog. If no path appears, open Task Manager, right-click the related process, and choose Open file location. Do not double-click the executable. - In File Explorer, right-click the file, choose Properties, and record the General tab’s location, file size, and creation date.
- Open Settings > Apps > Installed apps (called Apps & features on some Windows 10 builds) and look for the application that installed it. Write down its publisher and install date.
If there is no parent application, or the location does not match anything you installed, keep the file closed while you complete the security checks.

2. Check the digital signature
- In the file’s Properties, select Digital Signatures. Select a signature and choose Details.
- Confirm that Windows says the digital signature is valid. Open the certificate details and check that the signer matches the parent application’s publisher and that the certificate chain is trusted and current.
- Remember what a signature proves: it helps establish who signed the binary and whether it changed after signing. It does not guarantee that the software is desirable, bug-free, or safe in every context.
A missing signature is a reason for additional caution, not an automatic malware verdict. Conversely, a stolen or abused certificate can sign harmful software, so always combine the signature result with the path, origin, and scan.
3. Scan with Microsoft Defender
- Open Windows Security > Virus & threat protection.
- Install the latest security-intelligence updates. Under Scan options, choose Custom scan, select the folder containing
gamebooster.exe, and start the scan. - If the file was unexpected, follow with a Full scan. A clean custom scan is useful evidence but does not explain an unknown installer or persistent startup behavior.
Do not add the file to Defender’s exclusions merely to stop an alert. First determine why it was detected and which application placed it there.
4. Respond to a detection or suspicious origin
If Defender reports a threat, or the file arrived through a bundled or deceptive installer, disconnect the computer from sensitive accounts while you investigate. Do not sign in to banking, email, or work services on that machine until the scan and cleanup are complete. In Windows Security, allow the recommended quarantine or removal action, then remove the associated application from Settings.
If the file keeps returning, the browser changes unexpectedly, or Windows remains unstable, run Microsoft Defender Offline. The offline scan restarts the computer and checks before normal Windows processes load, which can reveal software that attempts to hide during a regular scan.

How to remove gamebooster.exe safely
When you recognize and no longer need the parent application
- Open Settings > Apps > Installed apps (or Apps & features).
- Find the game-booster or security application that owns the file, select the three-dot menu, choose Uninstall, and complete its wizard.
- Restart Windows. Check the original folder and Task Manager’s Startup apps list. Remove only leftover files that clearly belong to the uninstalled program; do not delete shared Windows files or an unknown executable merely because its name looks familiar.
- Run another Defender scan after the restart.
Uninstalling the parent program is safer than deleting the executable first. Deleting only gamebooster.exe can leave services, scheduled tasks, registry entries, or a broken installation behind, and a legitimate program may recreate the file.
When uninstall fails
Restart and try the Settings removal path again. If Windows reports that the program is running, close its game utility and end the related, verified process in Task Manager. If the entry is corrupted or the uninstaller is missing, use the publisher’s documented removal utility or contact the publisher rather than downloading a random “fixer.” Microsoft notes that unresolved unwanted-software cases may require contacting the publisher or resetting Windows while keeping personal files.
When malware is detected
Let Windows Security quarantine or remove the detected item, then remove the application that installed it. Do not restore a quarantined copy simply because a game stops launching. Run a full scan and, if symptoms continue, Microsoft Defender Offline. Review recently installed applications and startup entries for other items added at the same time.
Never download a replacement gamebooster.exe, DLL, or “gamebooster.exe fixer” from a random website. If the legitimate application is damaged, reinstall it only from its verified publisher or the Microsoft Store after the system is clean. Keep Windows and Defender updated before reinstalling.

Fix gamebooster.exe launch and crash errors
Capture the error before changing anything
Write down the exact message, any hexadecimal error code, the executable path, publisher, and the name of a faulting module if Windows displays one. Note when the problem started and what changed immediately beforehand: a driver, Windows update, game, peripheral, or security product. This information distinguishes an application fault from a wider Windows or hardware problem.
Repair the verified application
- Complete the malware checks above. Do not troubleshoot a potentially harmful executable by granting it permissions or adding exclusions.
- In Settings > Apps > Installed apps, select the recognized parent application. If Advanced options offers Repair or Reset, try Repair first; Reset may remove that app’s local settings.
- If no repair option exists, uninstall the parent application, restart, and reinstall a current copy from the verified publisher or Microsoft Store.
- Test the program before restoring optional overlays, mods, or bundled components. A crash that disappears after a clean reinstall points to damaged application files or configuration.
Check drivers and recently added hardware
A crash can originate in a graphics, audio, network, Bluetooth, USB, or other device driver rather than in the executable itself. If the issue began after connecting hardware or installing a driver, disconnect the newly added device when practical and test again. Roll back the changed driver when the hardware vendor provides that option, or install the current driver from the hardware or software vendor. Do not use an unverified driver package.
Use Safe Mode when normal Windows is unstable
- Open Settings > System > Recovery on Windows 11 or 10 and choose Restart now next to Advanced startup. On older systems, hold Shift while selecting Restart.
- Choose Troubleshoot > Advanced options > Startup Settings > Restart.
- Press 4 for Safe Mode or 5 for Safe Mode with Networking when network access is necessary.
- In Safe Mode, uninstall the verified parent application, remove a recently added driver, or run Defender Offline as appropriate. Restart normally and retest.
Safe Mode loads a limited set of drivers and startup programs. If the crash disappears there, a startup item, driver, or third-party component is more likely than the basic Windows environment to be responsible.

If Windows displays a blue-screen stop code or names a faulting module, record it exactly. Microsoft’s troubleshooting sequence is to remove newly added hardware, use Safe Mode when necessary, and use the displayed stop code or module name to narrow the cause. Search the code in Microsoft’s support documentation or the hardware/software vendor’s support channel rather than downloading an unverified repair utility.
When Windows remains unstable
After scans, application repair, driver checks, and Safe Mode troubleshooting, use Windows’ supported recovery options. Choose the least disruptive option that addresses the cause, such as System Restore when an appropriate restore point exists. If the program cannot be removed and Windows continues to malfunction, Microsoft identifies reset options that can keep personal files; back up important data first and follow the on-screen explanation of which applications will be removed.
Startup entries, pop-ups, and other warning signs
Review Task Manager > Startup apps and disable only entries you can identify. A legitimate game utility may start with Windows, but unexplained persistence, repeated relaunches, or a file in a temporary directory deserves investigation. Also check Settings > Apps > Installed apps for software added on the same date as gamebooster.exe.
A browser page or pop-up that says “gamebooster.exe is infected” and instructs you to call a phone number is not a normal Microsoft error. Microsoft states: “Microsoft error and warning messages never include phone numbers.” Do not call the number, install remote-access software, provide payment details, or disclose passwords. Close the page, run Defender from Windows Security, and use official Microsoft or software-publisher support channels.

Can you delete gamebooster.exe?
Delete it only after you have identified the owning application and decided that the application should be removed. If it is part of a program you still use, deleting the executable can break that program and cause repeated repair prompts. If it is a detected threat, use Windows Security’s quarantine or removal action instead of manually forcing deletion. If it is an unexplained leftover, document its path, scan it, uninstall any associated program, restart, and then reassess the remaining file.
Do not delete files from C:Windows, C:WindowsSystem32, or another shared location solely because the filename resembles a game utility. Confirm the publisher, path, and parent application first.
Optional shortcut
Outbyte PC Repair is an optional shortcut after you have completed the manual checks. It can address more than 100 common Windows issues where possible, including broken system elements and shared DLL problems, and offers settings tweaks, temporary and cache cleanup, privacy tools, vulnerability checks, a real-time boost, file shredder, and app-crash log. It runs on Windows 11, 10, 8, and 7; its free trial is available by category for at least two days before a paid subscription. It complements antivirus software rather than replacing it, results vary, and no tool repairs every crash.
Bottom line
gamebooster.exe is a generic filename, not a safety certificate. One documented copy is associated with 360 Game Booster and QIHU 360 SOFTWARE CO. LIMITED, but your file must be judged by its path, signature, parent application, installation source, startup behavior, and current Defender scan. Scan before launching, uninstall the parent application instead of blindly deleting the executable, repair or reinstall a verified copy for legitimate crashes, and use Safe Mode, Defender Offline, or Windows recovery when the problem persists. Treat phone-number warnings as scams and never use an unverified replacement executable or DLL.
