hi,
couple years back, i used Tweaking to ''fix'' my Win7 after YouTube videos keep stuttering..............problem solved but my anti-malware (Malwarebytes) then no longer work (doesn't matter)............recently, i cloned my HDD to SSD and following problems came about..............
1) the PC would freeze if my mouse is connected to the USB port at rear of PC......only working when connected to the front's USB port
2) my Realtek audio software disappeared but i got it back........but the Equalizer Settings would not save my settings
3) all the saved Log-in passwords needed to be keyed in again at websites (email, facebook, etc)
lastly, did Tweaking Win7 disabled the TRIM command for Win7 (IDE mode) ?
