I use Glary Utilities. I've also used CCleaner and others. Glary Utilities is on my computers
. In particular, I look at the startup manager and disable most things (Apple MobileDocuments, iTunesHelper, AppleSyncNotifier, ApplePhotoStream, ) Google
Update, FlashPlayerUpdate, SunJavaUpdateSched, QuickTime Task, Skype... and others that I don't want/need to run at startup. The less crap running at startup (in my opinion) the better.
I also use Glary Utilities Registry cleaner - run this several times to remove dependencies. So far, it has not caused any problems that I'm aware of.
Depending on the OS (WinXP, Vista, Win7).... I've gone through and disabled several of Microsoft Services. There are some comparisons on the Internet
talking about which services you can safely disable. You probably don't need Bluetooth, Certificate/Security, Distributed Transactions, Fax, HomeGroup, IKE/AuthIP, ICS, IP Helper, Net.Msmg, Net.Pip, Net.TCP, NetLogin, Offline Files, Parental Controls, Peer Name Resolution, Peer Networking, Performance Logs
, Portable Device, Problem Reports, Remote
Access, Remote Desktop
, Remote Registry, Secondary Logon, Secure Socket, Smart Card, Software
Protection, SPP Notification, Storage
Devices, Tablet PC, Telephone, Thread Ordering Server, TPM Based Services, UPnP Device Host, Virtual Disk, VOlume Shadow Copy, Windows Activation Technologies, Windows Biometric Service
, Windows CardSpace, WIndows Color System, WIndows Defender (?), Windows Error Reporting Service
, Windows Event Collector, Windows Installer, Windows Media*, Windowsd Remote Management, Windows Time, Wired AutoConfig, WLAN AutoConfig, WMI Performance Adapter, WWAN AutoConfig... I'm sure there are others that I should disable too!
When disabling services (Control Panel - Administration - Services), shut them off and set them to Manual, one or two at a time. Keep track of what you've changed. Run the PC for a while, do things you normally do. If all works, move to the next batch. Be careful with this.
Lastly, with Win7, there are several scheduled tasks that I don't need/want, so I've disabled them too.
To me, less is better. I want to keep my several year old Dell PC running. When it slows down, I become concerned about programs running at startup and unnecessary services. If you compare Linux
to Windows, considerably less hardware
is required for the same functionality. It is all the Microsoft, Adobe, Apple and now Google
consuming our machines!
