Fixed my Windows Update
Wasn't able to complete Windows updates for a few days, kept getting stuck at 90%. Looked it up online and came across this Windows Repair tool and gave it a try. I used the free version and ran the Windows Update option in Repairs and it worked! The updates didn't get stuck again.

Great support for solving my computer issue
I had for a long time a Kernel-Power 41 error on my Windows 11 laptop. Several blue screens on a day and I had tried many things. I tried Tweaking and it didn’t solve my issue on the first try, so I contacted the support team and they gave me a specific answer to solve it.

Check before you tweak
Most of the items tweaked are not that important, but if you put all things into perspective, it’s a software that does exactly what it says.
