5 Free Software You Probably Didn’t Know Existed (2026)

Five free Windows tools that solve common problems most users never realise have a free fix: HiBit Uninstaller for force-removing stubborn programs, WizTree for visualising what’s actually filling up your drive, SyncBackFree for scheduled local backups, LibreOffice Draw for free PDF editing, and ShareX for screen capture and screen recording. Each is actively maintained, has a portable version, and replaces a paid tool that costs $20-$80 per year.

Applies to: Windows 10 (22H2) and Windows 11 (23H2, 24H2, 25H2) | Last updated: April 30, 2026

Key Takeaways

• HiBit Uninstaller force-removes programs that refuse to uninstall and includes a registry cleaner, startup manager, and Windows Store apps manager — features that overlap with my own Winhance utility.
• WizTree scans an entire NTFS drive in under 2 seconds by reading the master file table directly, far faster than alternatives like WinDirStat or TreeSize.
• SyncBackFree handles scheduled local backups to external drives, network shares, and cloud sync folders — no subscription, no upload limits.
• LibreOffice Draw is the easiest free PDF editor: open the PDF, edit text and images directly, save back as PDF.
• ShareX replaces Snagit for screenshots, OBS for quick screen recording, and includes built-in upload to imgur, Dropbox, FTP, and over 80 other destinations.

1. HiBit Uninstaller — Force-Remove Stubborn Software

HiBit Uninstaller is what I keep on every PC for software cleanup. It hooks the program’s own uninstaller, runs it, then scans the registry and file system for everything that uninstaller missed — much like Revo Uninstaller, but free without limits and with a tighter UI.

The standout feature for daily use is Force Uninstall, which removes programs that no longer appear in Apps & Features (broken installs, half-updated apps, abandoned trials). Beyond uninstalling, HiBit bundles a Registry Cleaner, Junk Cleaner, Startup Manager (with VirusTotal scores per entry), Browser Extensions Manager, and Windows Store Apps Manager — five separate tools rolled into one.

1. Download the portable version (no installer, no admin needed).
2. Right-click any program and pick Force Removal.
3. After removal, run the leftover scan to delete files and registry keys the original uninstaller left behind.

2. WizTree — Disk Space Analyser That Finishes in Seconds

WizTree reads the NTFS master file table directly, so a 1 TB drive scans in 1-3 seconds — orders of magnitude faster than WinDirStat or TreeSize. The treemap view at the bottom makes the biggest files obvious at a glance.

Use it to find the surprise space-eaters: a forgotten 60 GB OneDrive cache, an old game install you forgot about, an Outlook PST that grew to 30 GB, or a pagefile/hibernation file you can shrink. For the actual cleanup workflow, see my clean C drive guide.

1. Download the portable version, run WizTree.exe.
2. Pick the drive (C: by default), click Scan.
3. In the file tree, sort by size descending. Right-click anything you no longer need to delete it.

Warning: Never delete files inside C:\Windows or C:\Program Files directly. Use Apps & Features or HiBit Uninstaller for installed programs.

3. SyncBackFree — Scheduled Local Backups

SyncBackFree handles the kind of “back up my Documents folder to an external drive every night at 2 am” task that Windows’ built-in File History does badly. Profiles can be Backup (one-way copy), Sync (two-way), or Mirror (one-way exact replica), and every profile supports filtering, compression, and encryption.

1. Install SyncBackFree and create a new Backup profile.
2. Set source (e.g., C:\Users\<you>) and destination (an external drive or network share).
3. On the When tab, schedule daily, weekly, or on-event runs.
4. Click Run Now for the first backup, then let the scheduler handle subsequent runs.

Pair SyncBackFree with a privacy-friendly cloud option like Proton Drive for off-site backups (see my local account vs Microsoft account guide for why I avoid OneDrive’s auto-sync).

4. LibreOffice Draw — Free PDF Editor

Adobe Acrobat costs $19.99/month for what most people use it for: editing a couple of words on a PDF or filling in a form. LibreOffice Draw, included free with the LibreOffice suite, opens any PDF, makes text and images directly editable, and exports back to PDF when you are done.

1. Install LibreOffice if you do not already have it.
2. Right-click the PDF → Open with → LibreOffice Draw.
3. Click any text frame to edit. Move or resize images by clicking and dragging.
4. File → Export As → Export as PDF when done.

For scanned PDFs (image-based), Draw cannot OCR the text — it just lets you overlay new text on top. For real OCR, use a free tool like Foxit Reader‘s text recognition or run the PDF through OnlineOCR first.

5. ShareX — Screen Capture, Recording, and More

ShareX is free, open source, and replaces a stack of paid tools: Snagit (screenshots), Loom (quick screen recordings), Greenshot (annotation), and the auto-uploader features of Cloudapp/Droplr. The only thing it does not do well is real broadcast streaming — for that, use OBS.

The killer feature is the post-capture pipeline. Configure ShareX to: capture a region → annotate it → save to a folder → upload to Imgur → copy the URL to your clipboard. All triggered by one keyboard shortcut. Once you set this up, every screenshot you take is one keystroke away from being shareable.

1. Install ShareX from the Microsoft Store, or via WinGet: winget install ShareX.ShareX.
2. Press Print Screen for a region capture, or Shift+Print Screen for screen recording.
3. Configure post-capture actions under Task settings → Screenshots → After capture tasks.

Frequently Asked Questions

Is HiBit Uninstaller safe?

Yes. HiBit Uninstaller is signed, has been around since 2018, and is detected as clean by Windows Security. It modifies the registry during force-uninstall — that is the whole point — but only inside the keys associated with the program being removed.

Can WizTree delete important system files by mistake?

WizTree never deletes anything automatically — every delete is an explicit right-click action. The risk is if you delete files inside C:\Windows or C:\Program Files manually. If unsure, leave anything in the Windows folder alone and use Disk Cleanup or Storage Sense instead.

Does SyncBackFree support cloud destinations?

The free version backs up to local folders, external drives, and network shares. To back up to OneDrive, Dropbox, or Proton Drive directly, point the destination at the local sync folder of those services — they upload automatically. For native cloud (FTP, SFTP, AWS S3) without a sync app, you need SyncBackPro (paid).

Is LibreOffice Draw a real Adobe Acrobat replacement?

For routine PDF edits — fixing a typo, replacing a logo, signing a form, redacting text — yes. For complex form workflows, OCR, redaction with full audit trails, or commenting at scale, Acrobat Pro still wins. But the routine edits cover 90% of why people pay for Acrobat.

Can ShareX record screen with audio?

Yes. Configure audio under Task Settings → Screen recording → Screen recording options — pick the audio source (microphone, system audio, or both) and the codec. The default H.264 + AAC settings are fine for sharing on Slack/Discord/email.
