Trying to remove bloatware.

Factory OEM can be reinstalled using the retail installer since Vista.

Manufacturers no longer provide clean-copy install DVD's in order to enforce their sponsor's bloatware since it provides most of their thin profit margin.

Many tech enthusiasts find a clean-copy DVD of their OS version and reinstall using the OEM Product Key on the COA sticker on machine. Any installer can also have all versions unlocked by extracting the ISO using ImgBurn then using the ei.cfg removal tool.

Make your Recovery DIsks or save a Win7 backup image of the entire HD first so you have a path back to factory condition. Then wipe the HD clean of factory code since links to useless factory utilties will be lost anyway: https://www.sevenforums.com/tutorials...tallation.html

The installer is mostly driver-complete, with newer arriving quickly via optional Windows Updates. Any drivers then missing in Device Manager can be found on the Support Downloads webpage for your model computer or device. Don't change drivers given by installer/Updates unless performance dictates.

Install programs slowly over time to gauge performance after each. Don't let any programs write themselves into msconfig>Startup as they become freeloaders on your RAM/CPU and can spy on you. I only allow AV and gadgets.

Use a lightweight free AV like MS Security Essentials which works perfectly with Windows 7 Firewall.

When it is finished, clean and order the HD perfectly using state-of-the-art free CCleaner then Auslogics Disk and Registry defraggers monthly.

Then save a Win7 Backup image externally so you never have to reinstall again, just reimage the HD or replacement using DVD or Repair CD.
