What this section changes
Work Windows starts on its own and never shows anywhere. None of these lowers a buffer or a timeout Windows provides; each either turns a switch off or raises a restriction.
| Setting | What it does | Registry path |
|---|---|---|
| Stop the telemetry trace sessions that start at boot | Windows starts a set of event tracing (ETW) sessions at boot and they collect until the machine shuts down. Turning off the telemetry service does not stop them — they are a separate mechanism, started by the kernel. Only telemetry and diagnostic sessions are stopped; Defender, the event log and ReadyBoot, which learns the boot sequence, are left alone. A session this machine does not have is never created. | HKLM\SYSTEM\...\Control\WMI\Autologger\<session>\Start |
| Stop Windows learning from what you type | Windows collects the text you type and your pen strokes to train its own suggestion model. This is not a scheduled task — it is work attached to input itself, running whenever you use the keyboard, including in game. The touch keyboard and pen keep working; only suggestion quality degrades over time. | HKCU\...\InputPersonalization + Input\TIPC\Enabled |
| Stop downloading device icons and details when hardware is plugged in | When new hardware is connected Windows tries to fetch an icon and description package from the manufacturer, and device installation waits for that request. It is a common cause of the few-second stall after plugging in a USB device. Driver installation is unaffected — what is skipped is the icon and description package. | HKLM\...\Device Metadata\PreventDeviceMetadataFromNetwork |
| Stop scanning USB sticks and external drives on insertion | When a drive or stick is connected Explorer scans it to classify the media, which on a large drive is seconds of disk and CPU. The value rises from 145 to 255 — each bit is a block, so the number goes up and protection increases. Side benefit: AutoPlay is the classic entry route for malware spread on removable media, and this closes it too. | HKLM\...\Policies\Explorer\NoDriveTypeAutoRun |
| Turn off Storage Sense | The job that scans temporary folders and the recycle bin in the background when the disk fills up or its own schedule comes round. It decides when to run — which can be mid-match. Once off the disk no longer clears itself; manual clean-up stays where it was. | HKLM\...\Policies\...\StorageSense\AllowStorageSenseGlobal |
| Turn off the pen workspace | The interface layer that waits for pen support. On a machine with no pen it does nothing but stays loaded. If you do have a pen, applying this stops the pen button and the Windows Ink tools working — the Fix page card turns it back on. | HKLM\...\Policies\...\WindowsInkWorkspace\AllowWindowsInkWorkspace |
Applying it
- Open w0a
- Go to the Regedit Tweaks page in the left menu
- Find this section, tick the settings you want, apply
Every setting is individually selectable — you are not required to apply a whole section.
Undoing it
Two ways, both of which work:
- Backups & Restore — puts back the checkpoint written before the change was applied. It
reverts what that group changed and touches nothing else.
- The Fix page — searched by symptom, writes the Windows default unconditionally. It does not
read a backup, so it works even if w0a's own backup file is gone.
The undo log lives at %ProgramData%\w0a\backup.json, outside your user profile.
The risk
Everything here is a documented value Windows supports; none of it is kernel-level and none of it is irreversible. The honest sentence is still this: a setting may have no measurable benefit for you. If you apply a change and feel no difference, you are probably right — these pages are not selling you a feeling, they are telling you what was changed.
If you want to measure it, the rule from reading the benchmark applies: change one thing at a time, and read the lows rather than the average.
