Windows 11 includes several built-in tools to help keep storage usage under control on your computer. Features like Storage Sense, the Temporary Files settings page, and Storage Recommendation can help you reclaim storage with ease, making third-party cleanup utilities less essential than they once were.

However, those features don't clean everything. If you want more control over temporary files, browser data, app caches, and privacy-related files, BleachBit is one tool you have to try. It's free, open source, and, unlike many PC "optimizer" apps, it focuses on cleaning unnecessary files rather than promising unrealistic performance improvements.

In this how-to guide, I'll explain what BleachBit does, how to use it on Windows 11, which settings I recommend, and which features you should avoid unless you understand exactly what they do.

What is BleachBit?

BleachBit is a free and open-source cleanup utility for Windows 11 that removes temporary files, caches, logs, browsing data, and other unnecessary files created by the operating system and many third-party apps.

Unlike many commercial cleanup tools, BleachBit doesn't include advertisements, bundled tools, or premium features. Instead, it gives you complete control over what gets removed and explains every cleaning option before you run it.

Rather than replacing the built-in cleanup tools available on Windows 11, I see BleachBit as an additional utility for users who want more control over what gets cleaned.

Why use BleachBit?

Although Windows 11 already provides several storage management tools, BleachBit adds several more capabilities.

For example, cleaning the system's temporary files as well as those junk files created by third-party apps. You can also use the tool to clean temporary browser data, such as cache, history, and downloads.

In addition, BleachBit provides secure file shredding to make recovery more difficult and wipes free storage space on supported drives.

Finally, the tool offers command-line support for scripting and automation, and there's a portable version that you can use without installation.

The biggest advantage is flexibility. Instead of cleaning everything automatically, BleachBit lets you decide exactly what should (and shouldn't) be removed.

Install BleachBit on Windows 11

Installing BleachBit is straightforward. You can download either the standard installer or the portable version, then launch the application. However, the quickest way to install the app is by running the winget install --id BleachBit.BleachBit command in Command Prompt (admin).

For most cleanup tasks, running it in normal mode is enough. Some system cleaning options may require administrator privileges.

Once opened, you'll notice a list of apps and cleaning categories on the left, along with a brief description of each option as you select it.

Always run Preview first

One feature I recommend using every time is Preview. Instead of immediately deleting files, the "Preview" option scans your system, estimates how much storage space can be reclaimed, and shows exactly what BleachBit intends to remove.

Even if you've used BleachBit before, I still recommend running the Preview option first.

Recommended cleanup options

For routine maintenance, I recommend starting with categories that are generally safe to remove.

For example, from the "System" section, some good choices include:

• Temporary files.
• Logs.
• Clipboard.
• Recycle Bin.
• Update uninstallers.

Usually, these items consume storage over time without affecting your daily workflow.

For browser cleaning, I suggest being more selective. Clearing cached files occasionally is perfectly reasonable, but deleting cookies will sign you out of websites, and removing session data will close saved browsing sessions.

Unless you're troubleshooting a browser issue or intentionally clearing your browsing activity, I usually leave those options unchecked.

The same advice applies to app caches. While they're generally safe to clear, some apps may take longer to launch the next time because they'll need to recreate those files.

As mentioned above, cleaning actions may require using the tool in Expert mode. If you receive the prompt, open the BleachBit main menu, select "Preferences," and choose the "Expert mode" option located in the "General" tab.

Securely delete sensitive files

BleachBit includes a built-in file shredder for permanently deleting sensitive files (and folders).

Unlike sending a file to the Recycle Bin (or even deleting it permanently with the "Shift + Delete" shortcut), secure shredding overwrites the file's contents before removing it, making recovery using standard data recovery tools much more difficult.

If you want to use this feature, open the BleachBit menu (the first icon at the top-left), choose the "Shred Files" option, then select the file to delete.

This feature is useful when you're deleting confidential content, financial records, or other sensitive files you don't want recovered later.

Wipe free disk space

The open-source tool can also overwrite unused space on a drive to remove traces of files that were previously deleted through the Recycle Bin.

This feature is intended primarily for drives before selling, donating, or retiring a computer, or for secondary drives.

The feature is available from the BleachBit main menu by selecting the "Wipe Empty Space" option and choosing the drive you want to clean.

I don't recommend running free-space wiping as part of regular maintenance because it takes time and provides little benefit for everyday use.

If you're preparing a device for resale, the Reset this PC feature is generally the better approach.

One feature you won't find

One thing that BleachBit doesn't offer is a Registry cleaner.

I actually consider that an advantage. For years, Registry cleaners have been marketed as a way to improve performance in the operating system, but in practice, they rarely provide measurable benefits. Worse, removing the wrong Registry entries can cause apps or the system itself to behave unexpectedly.

Microsoft doesn't include a Registry cleaner on Windows 11, and I don't think most users should use one.

By focusing on cleaning unnecessary files instead of modifying the Registry, BleachBit avoids one of the biggest sources of risk associated with older computer optimization suites.

Does BleachBit make Windows 11 faster?

Not directly. When you delete temporary files, you can free up storage space and occasionally resolve issues caused by bad caches, but it won't make your computer faster.

If Windows 11 feels sluggish because your drive is nearly full, cleanup may help. However, performance issues are usually caused by factors such as not enough memory, older hardware, too many startup apps, malware, or software conflicts, not because your temporary files folder is too large (at least not the majority of the time).

Should you use BleachBit?

If you're comfortable with the built-in cleanup tools available on Windows 11, you may never need another maintenance utility.

However, if you want additional control over browser data, temporary files, app caches, privacy-related cleanup, secure file shredding, and other advanced maintenance tasks, you may benefit from BleachBit.

The open-source nature, easy-to-use interface, and decision to avoid questionable features like Registry cleaning make it one of the few utilities for cleaning up Windows 11 and one of the few alternatives to CCleaner.

Windows Central's Take

In the many years I've used the desktop version of Windows, I've tested and relied on countless cleanup utilities. Some of them were genuinely useful at the time, but many were eventually discontinued, acquired by other companies, or changed so much that they no longer offered the same experience.

Over time, I've become much more selective about the tools I recommend, especially when it comes to software that makes changes to the operating system.

More often than not, I recommend learning and using the built-in tools. However, BleachBit takes a different approach, and that's why I think it stands out. It focuses on cleaning files, not "fixing" the operating system, and I appreciate that it skips gimmicks like Registry cleaning that can do more harm than good.

If you decide to use it, my advice is not to treat it like a one-click optimization tool. Take advantage of the Preview feature, understand what each option does, and only clean what you actually need. If you use it that way, I think BleachBit is one of the few maintenance utilities that still deserve a spot in your toolkit.

You can now provide feedback about the Microsoft Rewards Program through a new feedback portal. Similar to the new Xbox Player Voice forum, the Microsoft Rewards Feedback portal lets you suggest features, vote on feedback, and track the progress of changes.

The Microsoft Rewards Program has been around in some form for years, though it used to be under the Bing brand. You can earn points by using Microsoft services that you can then exchange for various rewards.

If you're deeply entrenched in the Microsoft ecosystem, you can earn a lot of points quickly. Over the years, I've used points to build up a library of movies. I value gift cards over other rewards, but you can also use your Microsoft Rewards points to enter sweepstakes and make donations.

I don't spend as much time earning points anymore because of the changes Microsoft rolled out this year.

Microsoft rolled out major changes to its rewards program in May, and some were received poorly. Those changes paired with the increase of the Xbox gift card cost have left plenty of room for feedback.

Generally speaking, points are less valuable than they used to be and there are fewer options for redemption. It's also harder to earn points in several ways.

I think there's a limit to how much we should complain about getting free things, but I think for many the effort to earn points is no longer worth it.

Most requested improvements to Microsoft Rewards

The Microsoft Rewards Feedback portal only launched yesterday, but a theme is already emerging. Several of the top pieces of feedback center around delivering more value to users.

"Redeem points for Game Pass subscriptions," reads the most upvoted piece of feedback. "Bring back Value for money gift cards for redemption," says another suggestion.

Other entries focus on community features, like creating a reward for people who complete 100% of a game or showing a badge on Xbox Live profiles that's related to Microsoft Rewards.

I predict requests to improve value will dominate the top of the Microsoft Rewards Feedback portal once it's given time to mature.

Microsoft finds itself on the receiving end of a lawsuit about "unreasonable and excessive noise" allegedly emitting from the tech giant's Fairwater datacenter in Mount Pleasant, Wisconsin. The suit seeks compensation for damages, though the amount asked for is unspecified.

The Fairwater datacenter was unveiled in September 2025. At the time, it was the largest and most advanced datacenter. The site launched with NVIDIA’s GB200 GPUs. Each rack can process 865,000 tokens per second.

Running those GPUs makes a lot of noise. Microsoft states that the noise levels meet levels required by local ordinances, but the company has taken additional steps to reduce noise.

Microsoft shared the following update on June 18, 2026:

"Our engineering team and consultants on-site investigated the source of the sound, conducted tests, and put noise mitigations in place. Several neighbors confirmed what our independent monitoring showed: that these mitigations fully resolved the issue. We continue to work on short-term mitigation, and over the next several months, we will also install additional sound reduction components and continue to monitor sound at the site."

Despite the measures taken by Microsoft, the lawsuit about the noise from the datacenter was filed on July 1, 2026.

The lawsuit claims that Microsoft has not taken the proper steps to reduce noise in the surrounding area:

"Defendant has failed to follow proper industrial practices to prevent the offsite emission of noise, and has failed to absorb, capture, mitigate, and/or prevent noise from escaping its Data Center, thereby invading the homes and properties of Plaintiffs and the Class."

The plaintiffs of the suit claim that a "low hum" of infrasound emits from the datacenter and that the sound cannot be measured easily on the decibel scale. Our colleagues at PC Gamer highlighted that one plaintiff claimed "the constant noise [affected] his sleep." The filing states that the noise is "not only excessive, but consistent and pervasive."

Since the lawsuit was just filed within the last week, it will likely be a while before we see it reach a conclusion.

A bizarre Windows 11 issue is causing a single, bloated folder to swallow massive amounts of storage. In extreme cases, the folder can balloon up to 500GB. Others have seen dozens of gigabytes eaten up by the folder.

A file called "CapabilityAccessManager.db-wal" is the culprit. Windows Latest took a deep dive into the situation and Microsoft has addressed that file with a recent update.

Capability Access Manager is related to granting apps permissions, such as letting an app know your location or giving an app permission to use your PC's camera. The CapabilityAccessManager.db-wal file can grow to be large, though eating up 500GB of storage is not an intended behavior. That's the size of that file for one Reddit user. Others have lost a similar amount of storage to the bloated file.

It appears that Windows 11 is wrongfully logging repeated events for access and then storing that information. Capability Access Manager is supposed to store large amounts of data, but it should store items more efficiently.

July's Patch Tuesday update should fix the issue. You can push the fix right away by installing an optional update.

A Microsoft support document outlines all the improvements rolling out normally (emphasis added):

• [Secure Boot] With this update, Windows quality updates include additional high confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. Devices receive the new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout.
• [Authentication] This update improves Netlogon secure channel connections between domain controllers, enabling successful connections from member servers to domain controllers set up before 2025.
• [Emoji Panel Update] The emoji panel (Windows key + period (.)) now uses GIPHY for GIF content following the deprecation of Google’s Tenor API. Starting June 30, 2026, install the latest Windows update to continue using GIFs in the Emoji panel. If you don’t update, you will see a "GIF service is not available" error in the panel. Installing the latest Windows update will restore access to GIFs.
• [Networking] This update improves how your device connects to shared network resources. Connections used by apps and system features, such as the NetUseAdd function, now work more reliably, including unauthenticated (null session) connections.
• [Recycle Bin (known issue)] Fixed: This update addresses an issue where the confirmation dialog might display an internal Recycle Bin file name instead of the original file name when permanently deleting a file. This issue might occur after installing the June 2026 security update (KB5094126).
• [Storage] This update improves disk space usage for the CapabilityAccessManager.db-wal file.
• [Taskbar] This update improves notification badge display across your apps. Notification counts and badge visuals now update correctly, helping you stay up to date with new activity.

The change log notes the issue related to the CapabilityAccessManager.db-wal file, but it does not go into much detail.

It is possible to delete the folder containing the CapabilityAccessManager.db-wal file, but you have to be careful. If you delete just the file or erase the wrong item, you could break your PC's Wi-Fi connectivity.

A Reddit user deleted the file and was no longer able to connect to Wi-Fi. In their case, removing the folder and restarting their PC fixed the issue.

If your PC works well and you have enough space for your everyday workflow, you don't have to do anything right away. You can simply wait for the fix to roll out next month.
