Put Windows Services back to their factory defaults when a tuning guide, "optimizer," or malware has broken them.
Services are tiny background programs Windows uses to run essential things like networking, printing, and Windows Update. Each service has a Startup Type (Automatic, Manual, Disabled) and a logon identity (Local System, Network Service, etc.). If those settings get changed — by a "tweaking" guide, malware, or an uninstaller that didn't clean up after itself — Windows can misbehave in confusing ways: the printer stops, searches return nothing, updates never install.
Service Repair knows the correct default values for hundreds of Windows services and can restore them one-click at a time.
Big buttons that restore whole families of related services at once:
Fixes wuauserv, BITS, Cryptographic Services, and others. Pair with Windows Update Repair when updates are broken.
Restores DHCP Client, DNS Client, Network Connections, Network Location Awareness, and WLAN AutoConfig. Use when the network works sometimes but not always.
Windows Defender, Security Center, Firewall, Base Filtering Engine. Start here if your antivirus won't open or Windows keeps complaining your PC is unprotected.
Critical services that almost everything depends on: RPC, Plug and Play, Task Scheduler, Windows Event Log. Use cautiously — only if the PC is obviously broken.
Restores the Print Spooler service and clears the stuck print queue. The universal fix for "my printer was working yesterday and now it isn't."
Sometimes the service isn't broken — the permissions on it are. Malware and buggy installers sometimes lock services so even administrators can't modify them. The Permission Repair buttons reset the security descriptor on a service back to its out-of-box ACL.
Chrome, Edge, and some third-party browsers install their own auto-update services. These buttons fix those services if they've been disabled or corrupted (a common symptom is "Chrome can no longer update itself").
Below the grouped buttons is a detailed list of every service currently on your PC. For each one, TuneBit shows:
Select a row that's out of spec and click Reset Selected to restore just that service. Handy when you know exactly which service has been messed with.
