Hi, my name is Claudeir. I'm an Independent Advisor and a Microsoft user like you.
Windows+R, type: control userpasswords2, select your user, Properties, group membership, check administrator, apply and Ok.
If it doesn't solve the problem, it could be a problem with the user:
-New user account.
Your user profile is a set of settings that make your computer look and work the way you want it to. It contains your desktop background settings, screen savers, pointer preferences, sound settings, and other features. Due to this variety of personal settings and changes caused by other programs can cause corruption of your user profile and malfunction in system usage hence the need for a new profile.
On the Desktop, press the Windows + R keys simultaneously to open Run;
In Run type control userpasswords2 and click OK; (There is a space after the control)
On the Add tab, and Sign in without a Microsoft account (not recommended).
Click to create a Local Account.
Enter a username and password, add a password hint and click Next and then Finish.
In the Users tab select the name of the new user click Properties;
On the Group Membership tab check the Administrator option, click Apply and OK;
Restart the computer and login to the new user account and see the behavior.
If it solves the problem, you can transfer the data to the new user:
In the admin user you created, press the Windows+R keys, type: %systemdrive%\users (in English and without spaces)
and click Ok. Check your previous user's folder and click the left mouse button, it may take a while to process the data, in a few minutes access to your files will be released, select the folders you want to move, to copy them press (CTRL+C), to cut them press (CTRL+X) and to paste press (CTRL+V) in your new user.
After migrating your data, delete your previous user: Press the Windows+R keys, type netplwiz and click OK. Select your previous user and click Remove.
Feel free to leave your opinion, marking it as answered if the answer helped, or leaving more details so we can continue the service, this is very important to us.
Sincerely,
Claudeir
