XFast PC Optimizer: Download, Install & Use Correctly [Guide]
Is your Windows PC running slowly, using too much memory, or taking longer than usual to launch applications? A PC optimization tool can help you monitor system resources, manage background activity, and perform routine maintenance.
XFast: PC Optimizer, RAM Booster & FPS Enhancer is a Windows utility available through the Microsoft Store. It offers features related to memory management, system monitoring, startup management, gaming optimization, and storage cleanup, although some tools require a paid plan.
In this guide, you’ll learn how to download and install XFast, check its availability on Windows 11 and Windows 10, and use its main features correctly.
Important: PC optimization software cannot guarantee faster performance or higher gaming frame rates. Results depend on your hardware, Windows configuration, and the applications running on your computer.
XFast PC Optimizer File
XFast is a Windows application designed to bring several PC maintenance and monitoring tools together in one interface. Instead of manually checking every resource in Windows, you can use its dashboard to review system information and access supported optimization features.
The application is listed on the Microsoft Store under the name XFast: PC Optimizer, RAM Booster & FPS Enhancer. Its developer is associated with the ArkiByte website.
Its feature set includes memory usage monitoring, system information, memory cleanup, startup management, junk-file cleanup, and gaming-related controls. Availability depends on the edition, and several advanced tools are listed as premium features.
Because XFast is a Windows application distributed through the Microsoft Store, you generally do not need to search for a separate EXE installer on third-party download websites.
The safest approach is to open its official Store listing, verify the application name, and install it from there.
XFast PC Optimizer: Download & Install
You can install XFast through the Microsoft Store or open its developer’s website to locate the official download information.
The Microsoft Store is the recommended starting point because it provides a direct listing for the application.
Step 1: Check Your Windows Version
Before installing XFast, confirm which version of Windows your computer uses.
Press Windows + I to open Settings. Select System, then select About. Under Windows specifications, check whether you are running Windows 11 or Windows 10.
Also check that your PC has enough available storage for the application and its updates. If you’re using a work computer, your administrator may restrict Microsoft Store installations.
Step 2: Open the Official Microsoft Store Listing
Open the link provided above in your web browser. Verify that the application name is XFast: PC Optimizer, RAM Booster & FPS Enhancer.
Select the option to open the application in Microsoft Store if Windows offers it. You can also open the Microsoft Store app from the Start menu and search for the complete application name.
Make sure you select the correct app rather than another utility with a similar name.
Step 3: Download XFast
On the Store listing, select Get, Install, or the equivalent option shown on your screen. The wording may vary depending on your Windows version and Store interface.
If prompted, sign in with your Microsoft account. Follow the on-screen instructions to begin downloading the application.
The listing identifies XFast as a free download with in-app purchases, so downloading the app does not mean every feature is free.
Step 4: Complete the Installation
Wait for the download and installation process to finish. If the Store displays an Open button, select it to launch XFast.
If installation fails, check your Internet connection, available disk space, and Microsoft Store updates. You can also restart your PC and try again.
Avoid downloading an unfamiliar EXE file from a third-party website simply because the Store installation fails.
Step 5: Launch XFast and Review Its Settings
After installation, open the Start menu and search for XFast. Select the application to launch it.
Review the initial permissions, settings, and any license or trial prompts. If a premium trial is offered, read its duration and purchase terms before accepting.
Once the application opens, take a few minutes to explore the dashboard before running any cleanup operation.
How to Use XFast PC Optimizer on Your PC?
XFast includes several optimization and monitoring features.
The exact tools available depend on your installed version and whether you have the free or premium edition.
1: Check Your PC’s System Health
Start with the System Dashboard or equivalent overview screen.
Review the available information about your RAM usage, CPU, operating system, and storage. Some versions also provide a system health score and recommendations.
Use these figures to understand your computer’s current condition. For example, if memory usage remains high while you have several applications open, check which programs are consuming the most RAM before deciding whether cleanup is necessary.
Remember that high memory usage is not automatically a problem. Windows uses available RAM to improve performance, and clearing memory does not necessarily make a PC faster.
2: Monitor and Clean Memory
Open the Memory Cleaner or memory optimization section, depending on your version.
Review the displayed memory usage and available cleanup options. If your computer is struggling because several nonessential applications are running, close applications you do not need before attempting a memory cleanup.
If XFast offers a quick memory-cleaning function, use it only when you understand what it does. Memory-cleaning operations may reclaim some resources temporarily, but they cannot replace adding more RAM when your computer regularly runs out of memory.
Avoid repeatedly cleaning RAM just to keep the usage percentage low. Windows normally manages memory automatically.
3: Use Deep Memory Cleaning Carefully
If your edition includes Deep Memory Cleaning, open the feature and review its available categories or presets.
Depending on the version, the tool may target reclaimable memory, browser working sets, and selected caches. Some advanced cleanup options require premium access.
Read the cleanup description before proceeding. Save open documents and pause any important downloads before cleaning browser-related data.
If the feature offers separate options, select only the categories you understand.
Avoid aggressive cleanup settings when you are unsure whether an application depends on the affected cache or temporary files.
4: Optimize Startup Applications
Open Startup Manager if it is available in your edition.
Startup applications launch automatically when Windows starts. Too many unnecessary startup programs can increase boot time and consume resources in the background.
Review the listed applications and identify programs you recognize but rarely need immediately after signing in. Disable only those you are comfortable starting manually later.
Do not disable security software, essential device utilities, or unfamiliar system components without researching them first. If Startup Manager is unavailable in your free edition, Windows provides a similar option under Settings > Apps > Startup in Windows 11 or through the Startup tab in Task Manager.
5: Clean Unnecessary Files
If your edition provides Junk Cleaner, open it and run a scan.
Review the results before deleting anything. Pay particular attention to browser caches, temporary files, and any categories that may contain information you want to retain.
Do not remove Downloads, personal documents, saved work, or application data simply because a cleanup tool labels them as unnecessary. If the tool identifies a file you do not recognize, leave it alone until you understand its purpose.
Keep in mind that some cleanup features may require premium access.
6: Use Gaming Mode
If you have access to Gaming Mode, open the feature before launching a game.
Review which background processes, services, notification settings, or priority options the mode may change. Close applications you do not need and save your work before starting an optimization session.
Some gaming tools can temporarily stop selected background services or close processes. This may affect applications that you expect to keep running, such as cloud synchronization tools or communication apps.
When you finish gaming, turn Gaming Mode off and check that your normal applications work as expected. Gaming Mode may reduce background activity, but higher FPS is not guaranteed.
7: Review Storage and Installed Applications
If Storage Analyzer is available, use it to identify folders or categories consuming significant disk space.
Review the results before deleting files. Large videos, old installers, and duplicate downloads may be good candidates for manual cleanup, but confirm that you no longer need them.
If you use Advanced Uninstaller, review the installed application list and select only programs you recognize and no longer use. Read any residual-file or force-removal warnings carefully because these operations can remove application files and registry entries.
8: Use Registry Cleaner With Caution
If your version includes Registry Cleaner, begin by scanning the registry and reviewing the reported results.
Do not automatically fix every entry just because the application identifies it as an issue. Incorrect registry changes can affect installed programs or Windows behavior.
If you choose to use this feature, create a suitable backup or restore point first, and use the application’s backup option if available. Select only fixes you understand.
For most everyday performance issues, you should troubleshoot the underlying problem before attempting registry cleanup.
9: Configure Automatic Optimization
Some editions include Performance Guardian or scheduled cleaning options. These tools can monitor memory pressure or run selected maintenance tasks automatically.
If you enable automatic optimization, start with conservative settings. Review the thresholds, cooldown periods, battery-related options, and notifications available in your version.
Avoid scheduling frequent deep cleanups without a specific reason. Monitor how your computer behaves and disable automation if it interrupts your work or causes applications to behave unexpectedly.
Additional Tips
Keep Windows updated. Install appropriate Windows updates and hardware drivers rather than relying entirely on an optimization utility.
Check Task Manager first. Press Ctrl + Shift + Esc to identify applications using excessive CPU, memory, or disk resources. This can help you find the actual cause of slow performance.
Create a restore point before advanced changes. This is especially useful before making registry changes or modifying system services.
Understand the free and premium editions. XFast’s listed free edition includes basic memory cleaning, a system dashboard, RAM monitoring, and system information. Several advanced features require premium access or an eligible trial.
Do not expect miracles. An optimizer cannot reliably solve hardware faults, malware infections, a failing drive, overheating, or insufficient system memory. Address the underlying cause instead of repeatedly running cleanup tools.
