How to clean your Windows 10 or 11 system disk

    These days, a comparatively clear and uncomplicated Windows 10 or 11 system disk is likely to be dwelling to greater than 250,000 recordsdata and 90,000 folders. A extra advanced, application-heavy system disk would possibly comprise between half 1,000,000 and 1,000,000 recordsdata. My Windows 11 manufacturing PC has over 970Ok recordsdata and 275Ok folders, for instance. That’s numerous stuff!Indeed, all these recordsdata needn’t essentially be saved round. That’s why it’s a good suggestion to apply common disk hygiene. This is strictly what’s defined and explored right here, with loads of examples and display pictures for instance the cleanup course of. Best of all, the instruments that provide help to tidy up gained’t price you a dime.Step 1: Run built-in Windows disk cleanup toolsFrom time immemorial, Windows has included a utility for cleansing up disk area — particularly, Disk Cleanup, also called cleanmgr.exe. In Windows 10, customers gained a second methodology to wash up disk area: the “Free up space now” possibility is a part of its Settings-based “Storage Sense” facility aimed toward optimizing storage. In Windows 11, this exhibits up as “Cleanup recommendations.”There has been hypothesis that Disk Cleanup would possibly disappear as Settings takes over Windows administration and controls. Even so, the Disk Cleanup utility stays prepared, keen, and capable of work in Windows 11 22H2 as I write this story. Either the Settings or Disk Cleanup method supplies an effective way to excise extraneous and unneeded Windows recordsdata (for Windows 10 and 11 variations throughout the board).To launch Disk Cleanup, sort disk clear or cleanmgr.exe into the Start menu search field. The Disk Cleanup desktop app ought to seem on the prime of these search outcomes. If you’ll be able to, choose Run as administrator from the ensuing choices menu. Why? Only then does it provide to wash up redundant or outdated OS recordsdata (comparable to previous OS recordsdata after an improve, or previous updates) in addition to different Windows leftovers.After Disk Cleanup scans your system, Figure 1 exhibits an affordable facsimile of what you’ll see in Windows 11.

    Figure 1: When you run Disk Cleanup as an administrator, you’ll be able to take away “Previous windows installation(s)” and different OS recordsdata.

    Scroll by means of the checkbox objects within the pane labeled “Files to delete” and choose stuff you’d prefer to lose. The numbers in the appropriate column point out how a lot disk area every merchandise occupies. Don’t delete previous OS variations or updates when you assume you would possibly wish to roll again to an earlier model. Note additionally that the Downloads merchandise represents the contents of your private Downloads folder, so don’t delete it until you’re certain you don’t want something it holds.Figure 1 features a earlier Windows 11 set up, for a complete restoration of 12.7GB. That’s a large chunk of disk area. In Windows 10, the Settings-based cleanup possibility is on the market by means of Settings > System > Storage > Configure Storage Sense or run it now > Free up area now. On the “Free up space now” pane, click on the Clean now button. This cleans up storage in a lot the identical manner as when you’d run Disk Cleanup and clicked all obtainable containers — eradicating momentary recordsdata, replace or improve recordsdata, supply optimization recordsdata (designed for sharing in your native community however seldom used), out of date system driver packages, and extra. It may even empty the recycle bin.This course of can — and infrequently does — take a number of minutes to finish. While it’s operating, it seems like what’s proven in Figure 2. Ed Tittel / IDG

    Figure 2: In Windows 10, it’s important to click on quite a few choices to get to “Free up space now.” After that, it really works silently to wash issues up.

    Windows 11’s “Cleanup recommendations” function is on the market by means of Start > Settings > System > Storage > Cleanup suggestions. On the “Cleanup recommendations” pane, click on Advanced choices. These choices seem in Figure 3, with checkboxes to pick (or keep away from) their contents for deletion. Ed Tittel / IDG

    Figure 3: The following objects are checked for cleanup in Windows 11: recycle bin, suggestions hub logs, supply optimization recordsdata, improve logs, non-critical Defender recordsdata, momentary web recordsdata, Windows error reviews and diagnostics, momentary recordsdata, DirectX Shader cache recordsdata, and person file historical past.

    The whole disk financial savings from this specific cleanup choice in Windows 11 come to simply beneath 3.5GB, much like what you’d get from Disk Cleanup. It takes a little bit of time to learn by means of and choose what you need, nevertheless it’s fairly straightforward to make use of. Some could discover it preferable to Disk Cleanup, in actual fact. Step 2: Run UnCleaner to catch what built-in instruments missJosh Cell is a Francophone developer in Canada who’s constructed a peachy and free utility known as UnCleaner. It can ferret out and take away momentary and out of date log recordsdata that even Windows’ built-in utilities don’t catch and kill. You can obtain the most recent model of UnCleaner (1.7) from Major Geeks. Don’t fear that this instrument exhibits a 2012 date: I can attest it nonetheless works effective on Windows 10 and 11 techniques in mid-2023.Running on the identical manufacturing PC upon which I simply ran Disk Cleanup, UnCleaner finds practically 400MB of recordsdata to wash up regardless of a notionally clear standing, as proven in Figure 4. Ed Tittel / IDG

    Figure 4: UnCleaner finds 594 further recordsdata to wash after Disk Cleanup is completed.

    Simply click on the Clean button (decrease left) to excise these recordsdata. You’ll by no means get this instrument to delete the whole lot it reviews, as a result of a few of these recordsdata are locked by Windows runtime constraints. But generally you’ll see a message that claims, “Good. Your system is very clean.” ‘Nuff said!Step 3: Use DriverStore Explorer to dismiss obsolete device driversDriverStore Explorer (RAPR.exe) is a free, open-source tool that you can download from GitHub. Always be sure to grab the most current release (0.11.92 as of this writing). Unless you’re an actual Windows driver wizard, you want solely click on two buttons to make RAPR do its factor: Select Old Driver(s) and Delete Driver(s). You should, nonetheless, run RAPR in administrator mode (right-click its icon and choose Run as administrator). When you begin it up, you’ll see a listing of put in drivers with checkboxes. Click the Select Old Driver(s) button on the prime proper of the display, and this system will routinely examine the containers for the older driver variations it finds. They’re highlighted with blue checkmarks in Figure 5. Ed Tittel / IDG

    Figure 5: Click Select Old Driver(s) to focus on objects for deletion, then click on Delete Driver(s). (Click picture to enlarge it.)

    When you click on Delete Driver(s), RAPR will try and take away all highlighted objects. It gained’t really take away any it finds in use, so it is a surprisingly protected operation. Power customers and specialists can discover much more for RAPR to do (see “How to reduce Windows driver bloat” for particulars), however most common customers will merely get pleasure from its potential to wash up previous, outmoded drivers.Notice in Figure 5 {that a} raft of Intel Bluetooth drivers is among the many objects focused for deletion. That’s as a result of the Intel Driver & Support Assistant retains on putting in Bluetooth drivers (month-to-month, if no more usually). This makes for many duplicates. The present alternatives will get well 635MB of disk area.I’ve seen some RAPR runs get well a number of gigabytes, however area financial savings are seldom bigger than that. First-time customers could get well 3 to 5GB when cleansing up quite a few driver recordsdata. (Graphics drivers usually exceed 1GB in measurement; these add up shortly.)Step 4: Use DISM to wash the Component StoreMost Windows OS recordsdata reside within the WinSxS folder, also called the Component Store. After you put in a cumulative replace, and generally after different updates, the Component Store could comprise duplicate, out of date, or orphaned components. You can use the Deployment Image Servicing and Management (DISM) instrument on the command line to examine the Component Store now and again. Such checks will inform you if a cleanup is required.To get began, you’ll must open an elevated PowerShell or Command Prompt window. On the Windows desktop, press the Windows key and X, then choose Windows PowerShell (Admin) from the ensuing pop-up menu. (Alternatively, you’ll be able to sort powershell into the Start menu search field, then right-click Windows PowerShell and choose Run as administrator from that pop-up menu.) In the Administrator: Windows PowerShell window that seems, sort this string and hit Enter:dism /on-line /cleanup-image /analyzecomponentstoreYou’ll see one thing like what’s proven in Figure 6. Ed Tittel / IDG

    Figure 6: DISM /analyzecomponentstore finds one package deal for cleanup (reclamation).

    As I wrote this story, I had simply put in a Cumulative Update and different replace objects earlier that week. Sure sufficient, /analyzecomponentstore reported that there was one reclaimable package deal prepared for cleanup. Notice that the response textual content reported “Yes” within the area labeled “Component Store Cleanup Recommended.” That’s your clue that DISM has one thing it may well clear up in your behalf.To make that occur, within the Administrator: Windows PowerShell window, enter this string:dism /on-line /cleanup-image /startcomponentcleanupThe outcomes seem in Figure 7, with an additional /analyzecomponentstore to point out the outcomes of the cleanup. Ed Tittel / IDG

    Figure 7: The cleanup operation completes. (The first 10% completion line is a recognized Windows bug.)

    When the numbers for the second /analyzecomponentstore operation get in comparison with the primary, we see the next numbers:
    Size of element retailer: 10.26GB vs. 7.35GB (diff: 2.91GB)
    Actual measurement of element retailer: 9.81GB vs. 7.18GB (diff: 2.63GB)
    Shared with Windows: 6.10GB vs. 6.07GB (diff: 0.03GB)
    Backups and disabled options: 3.70GB vs 1.11GB (diff: 2.59GB)
    If you add the financial savings for “Shared with Windows” and “Backups and disabled features,” you get 2.62GB, which is sort of the financial savings within the precise measurement of the element retailer (2.63GB) — simply appropriately. Recently up to date techniques could get well as much as 3 and even 4GB utilizing this system. (Actual outcomes rely upon the quantity and measurement of reclaimable packages eliminated.)For extra extremely helpful issues you are able to do with DISM, see “Why DISM is the Swiss Army knife of Windows maintenance.”Step 5: Inspect the system drive utilizing WizTreeOnce all previous cleanups are full, it’s a good suggestion to examine the system drive to see the place the massive recordsdata are. I take advantage of the free, donation-ware WizTree program, however TreeSize Free is a worthy various. Both applications produce treemap diagrams — graphical renderings of disk contents that make it straightforward to identify huge recordsdata and folders.Figure 8 exhibits the C: drive from my Lenovo X12 Hybrid pill. Ed Tittel / IDG

    Figure 8: WizTree shows the disk contents in a treemap diagram, the place field measurement exhibits how file (and folder) sizes evaluate to at least one one other. (Click picture to enlarge it.)

    Remember, you’re searching for huge recordsdata, as a result of eliminating them supplies helpful, fast wins within the disk area restoration recreation. Right right here, I see that the most important recordsdata are those you’d anticipate to see­ — particularly, the system hibernation file (hiberfile.sys) and the system web page file (pagefile.sys), in inexperienced at higher proper.After these behemoths (6.3 and a pair of.4GB, respectively), the following largest recordsdata seem in OneDrive (picture folders in greenish-yellow and purple, middle) and within the Windows Recovery agent ($WinREAgent, royal blue at decrease proper). All is as I’d anticipate. If I wanted to save lots of area, although, I’d see about pruning the pictures and movies in OneDrive.By clicking different “big blocks” within the treemap, you’ll be able to shortly determine the place your largest potential area restoration alternatives lie. You gained’t be capable of do away with all of them — the paging and hibernation recordsdata should keep, for instance — but when a few of them can go, huge area financial savings may result.Practice makes goodIf you carry out such cleanups periodically (I shoot for a minimum of as soon as a month), you’ll be capable of hold your area consumption beneath significantly better management. Try this routine out for your self and also you’ll quickly see what I imply. And don’t neglect to slog by means of the Users folder (particularly your account subfolder) now and again, too, as a result of junk too usually tends to build up there.Then, you’ll be able to blissfully get pleasure from your clear machine!This article was initially printed in January 2019 and up to date in September 2023.
