Choose the right tool#
| I want to… | Use |
|---|---|
| Prepare a recovery option before changes | System Restore Point |
| Check Windows system files | SFC & DISM Scan |
| Free space on drive C: | Disk Cleanup |
| Review disconnected device entries | Old Devices Cleanup |
| Undo supported TinyBoost changes | Reset All Settings |
System Restore Point#
Create a Windows restore point on C: before making changes
A restore point is a snapshot of your Windows settings that you can go back to later. It doesn't touch your personal files.
Click Create Restore Point. You'll see "Creating restore point…" and then "Restore point saved successfully!".
If Windows System Restore was switched off on your PC, TinyBoost switches it on for you and says so.
Tip
TinyBoost attempts automatic restore-point creation periodically. Before a significant change, create one here and check for the success message.
SFC & DISM Scan#
Scan and repair Windows system files
This asks Windows to check its own files for damage and repair anything it finds. It's the standard fix for a Windows install that's behaving oddly.
Click Run Scan. A full-screen progress panel opens with a timer and a list of steps.
Allow time for the scan
A scan and repair can take 30 minutes or more. Watch the current step and let it finish. Use Cancel if you need to stop, then wait for the app to finish cleanup.
Disk Cleanup#
Scan drive C: and free up space
Deletes junk files to free up hard drive space. It's a two-step process and nothing is deleted until you say so.
Do this
- Click Scan Drive C:. You'll see the progress and which category it's measuring.
- A checklist appears with every category and exactly how much space it's using, plus a Total to clean figure.
- Untick anything you want to keep.
- Click Clean Selected.
What each category is#
| Category | What gets deleted | Worth knowing |
|---|---|---|
| Downloaded Program Files | Old browser add-on leftovers | Review the category before deleting |
| Temporary Internet Files | Your browser and system web cache | Websites may load slightly slower once |
| DirectX Shader Cache | Pre-processed graphics data | Games may take longer to load or stutter while this rebuilds |
| Delivery Optimization Files | Cached Windows update data | Review the category before deleting |
| Recycle Bin | Everything in your Recycle Bin, permanently | Not ticked by default: tick it only if you're sure |
| Temporary files | Windows scratch files | Review the category before deleting |
| Thumbnails | Small preview images for your photos and videos | Picture folders feel slow once while they rebuild |
| Windows Update Cleanup | Old downloaded Windows updates | Review the category before deleting |
| Microsoft Defender Antivirus | Antivirus scan history | You lose your past scan and quarantine history |
| Windows upgrade files | Leftovers from a Windows version upgrade | Can stop you rolling back a recent big Windows update |
This cannot be undone
Deleted files are gone permanently. There's no recycle bin for them. Check the list before you click Clean Selected.
Anything currently in use is skipped rather than forced. At the end you'll see something like "Freed 4.2 GB", or "Freed 4.2 GB (17 items skipped)" if some files were locked.
Review the selected categories before cleaning. In particular, Recycle Bin can contain personal files you still want to recover.
Old Devices Cleanup#
Scan disconnected device entries and remove safe ghost devices
Over the years Windows keeps a record of every USB stick, headset, monitor and printer you've ever plugged in. Old entries for things you no longer own are called "ghost devices". They do no harm but they clutter Windows up.
Click Scan Old Devices, then Review Devices to see what was found. Tick the ones to remove (or Select All) and remove them.
If your Windows version is too old, the card says "Requires Windows 10 version 2004 or newer" and the button is disabled.
If nothing is found, you'll see "No safe old devices found": that's a good result.
GPU Update#
Clean install your NVIDIA driver
Also appears on the GPU tab, which is where it's fully explained.
The status line tells you Update available (yellow) or Driver is up to date (green). Click Check for Updates to look, or Manage once a check has run.
Reset All Settings#
Reset TinyBoost's settings to default
Use this to reset supported TinyBoost changes and saved performance profiles. It cannot recover deleted files or every removed app. For a single change, try that tool's own undo first.
Do this
- Click Reset Everything.
- The button is replaced by Are you sure? with Cancel and a red Reset Everything.
- Click the red one.
When it's finished you'll see "Restart your PC for the reset to take effect." Please do restart.
It cannot run while optimizations are active (the card says "Disabled while optimizations are active"), during the CS2 benchmark, or during a graphics card stress test. Finish those first.
