Well ,since after I activated Office 2016 with the Microsoft Toolkit my notebook is creating some strange files. I tried deleting, but they keep getting created. My notebook always had Windows 10 and I never tried to install another one. Sorry for any mistakes, english is not my native tongue.
#1. MTK was downloaded from the thread here at MDL? #2. Did you upgrade from Anniversary to Creators Update? #3. To avoid recreation, use diskcleanup (like Enth already suggested) to purge the old install files.
#1. Yes, the torrent one #2. My Windows 10 is the Creators Update for quite some time, since May #3. I tried using the cleanmgr.exe as an Administrator and the store settings
You could try to use a program called RKILL, then run virus scan to see if it is a virus, The behaviour of what you describing could be a virus or malware. For malware you could use a program call Malwarebyes which is completely free program to use or Glary Utilities which is completely free to use. The programs have limited abilities because your using the free versions but able to remove some of the most annoying malware and answer the question as to if that is whats happened. Something is telling your files system or os to put Windows.old back into the directory after being removed which is got me curious. Rkill of course is completely free.
If i was right and you are able remove the virus or malware then repeat again what Slave77 suggested and you should hopefully be good. Good Luck!!!
Sorry s1ave77 i should call you by your proper name, Problem with me is sometimes i get typing to fast.
