Hi I just created an account here because there seems to be a number of interesting threads and such that all required registration to see, but I also had a problem that I figured i'd post since it seems uncommon. I had a PROPERLY PAID FOR Windows 10, by which I mean I originally bought at full price a Windows 7 retail key which has migrated with hardware to a registered Windows 10. (this hasn't been cracked or 'activated' or any kind of work around) It wasn't OEM or such because I paid for all my software back when I got it and I had more than one key at the time even. (I cant 100% remember if it was home or professional or what, i think professional because I was using it with again properly paid for adobe creative cloud at college and then for freelance) Since installing it to some other older hardware (clarksdale dual core with 4gig ram, would be 8gig but i cant make it see more than 3gig despite being 64bit windows for reasons i cant diagnose) with a fresh Windows 10 install and the properly recognized key from the win 7 era the computer I put it on has run horrible due to all the background crap constantly going. Cortana sucking ram, unwanted search indexing, Error Reporting thrashes the drive at least a dozen times a day to upload all my private in-RAM data to microsoft i'm sure, and so forth. So I tried several of the decrapifier programs like O&O Shut Up 10 and similar - but none of them EVER makes or saves any changes no matter what I do. Nor can I seem to disable most services or tasks, it's like my version of W10 is locked down somehow. I don't know if this is uncommon or rare or what but in frustration I finally ended up back on Windows 7 because the computer became completely unusable. (simply browsing firefox would go to 100% ram usage, then hardlock and hard drive thrash without even the mouse moving for at least 5-10 minutes usually with me shutting off in the middle of it in frustration) Does anyone have any suggestions on how I could narrow down why my W10 is locking out changes or is this something that has happened to others?
